  • Selecting a specific div from a extern webpage using CURL

    - by Paulo
    Hi can anyone help me how to select a specific div from the content of a webpage. Say i want to get the div with id="body" from webpage http://www.test.com/page3.php My current code looks something like this: (not working) //REG EXP. $s_searchFor = '@^/.dont know what to put here..@ui'; //CURL $ch = curl_init(); $timeout = 5; // set to zero for no timeout curl_setopt ($ch, CURLOPT_URL, 'http://www.test.com/page3.php'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); if(!preg_match($s_searchFor, $ch)) { $file_contents = curl_exec($ch); } curl_close($ch); // display file echo $file_contents; So i'd like to know how i can use reg expressions to find a specific div and how to unset the rest of the webpage so that $file_content only contains the div.

  • How to replace for-loops with a functional statement in C#?

    - by Lernkurve
    A colleague once said that God is killing a kitten every time I write a for-loop. When asked how to avoid for-loops, his answer was to use a functional language. However, if you are stuck with a non-functional language, say C#, what techniques are there to avoid for-loops or to get rid of them by refactoring? With lambda expressions and LINQ perhaps? If so, how? Questions So the question boils down to: Why are for-loops bad? Or, in what context are for-loops to avoid and why? Can you provide C# code examples of how it looks before, i.e. with a loop, and afterwards without a loop?

  • scala REPL is slow on vista

    - by Jacques René Mesrine
    I installed scala-2.8.0.RC3 by extracting the tgz file into my cygwin (vista) home directory. I made sure to set $PATH to scala-2.8.0.RC3/bin. I start the REPL by typing: $ scala Welcome to Scala version 2.8.0.RC3 (Java HotSpot(TM) Client VM, Java 1.6.0_20). Type in expressions to have them evaluated. Type :help for more information. scala> Now when I tried to enter an expression scala> 1 + 'a' the cursor hangs there without any response. Granted that I have chrome open with a million tabs and VLC playing in the background, but CPU utilization was 12% and virtual memory was about 75% utilized. What's going on ? Do I have to set the CLASSPATH or perform other steps.

  • Permanently write variables to a php file with php

    - by Oliver
    I need to be able to permanently change variables in a php file using php. I am creating a multilanguage site using codeigniter and using the language helper which stores the text in php files in variables in this format: $lang['title'] = "Stuff"; I've been able to access the plain text of the files using fopen() etc and I it seems that I could probably locate the areas I want to edit with with regular expressions and rewrite the file once I've made the changes but it seems a bit hacky. Is there any easy way to edit these variables permanently using php? Cheers

  • Regex to match CSV file nested quotes

    - by user361970
    Hi, I know this has been discussed a million times. I tried searching through the forums and have seen some close regex expressions and tried to modify them but to no avail. Say there is a line in a csv file like this: "123", 456, "701 "B" Street", 910 Is there an easy regex to detect "B" (since its a non-escaped set of quotes within the normal CSV quotes) and replace it with something like \"B\" ? The final string would end up looking like this: "123", 456, "701 \"B\" Street", 910 Help would be greatly appreciated!

  • C# Lambda Problem

    - by Chris Klepeis
    Probably something simple, but as I'm new to lambda expressions, the problem evades me: m => m.contactID == contactID && m.primaryAddress == true && (m.addressTypeID == 2 || m.addressTypeID == 3) I tried to use that lambda expression but I receive an invalid operator. Is there a way to simplify this so that it would work? Edit: The equivolent sql query would be: SELECT * FROM Contact WHERE contactID = 3 AND primaryAddress = 1 AND (addressTypeID = 2 OR addressTypeID = 3) I have a repository function defined like so: public E Single(Expression<Func<E, bool>> where) { return objectSet.Single<E>(where); } I'm passing the lambda expression above into this function. Invalid operator error.

  • Struts/JSP/J2EE performance and memory profiling and issues

    - by Berlin Brown
    We are using Struts and having performance issues. And making heavy use of jsp includes, tiles, EL expressions. I am sure this is eating up a lot of memory and processing time. What are some approaches to profile the JSP page? What tools could I use? What should I look for when profiling? I have seen the code generated JSP Java Servlet Code and I see the bottlenecks but would rather measure it more accurately. This is under JDK1.5 and IBM Websphere 6.1 (RAD7)

  • Algorithm to match natural text in mail

    - by snøreven
    I need to separate natural, coherent text/sentences in emails from lists, signatures, greetings and so on before further processing. example: Hi tom, last monday we did bla bla, lore Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua. list item 2 list item 3 list item 3 Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquid x ea commodi consequat. Quis aute iure reprehenderit in voluptate velit regards, K. ---line-of-funny-characters-####### example inc. 33 evil street, london mobile: 00 234534/234345 Ideally the algorithm would match only the bold parts. Is there any recommended approach - or are there even existing algorithms for that problem? Should I try approximate regular expressions or more statistical stuff based on number of punctation marks, length and so on?

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

  • More HtAccess Rewrite Rules

    - by pws5068
    Greetings all, I need help combining some htaccess rewrites, these crazy regular expressions screw with my head. So I have a folder structure something like this: /www/mysite.com/page/member/friends.php /www/mysite.com/page/video/videos.php /www/mysite.com/page/messages/inbox.php The URLs get rewritten to this: mysite.com/member/friends.php mysite.com/video/videos.php mysite.com/messages/inbox.php (Notice the /page/ folder is hidden in the url, but I keep it on the server for better file organization) The rewrite rules look something like this: (I'm new so correct me if they are flawed) RewriteRule ^video/(.*)$ /page/video/$1 [NC] RewriteRule ^member/(.*)$ /page/member/$1 [NC] RewriteRule ^messages/(.*)$ /page/messages/$1 [NC] Now, I also need to do a completely different rewrite to a file called lobby.php inside of the member folder: After the original rewrites, a sample url looks like: mysite.com/member/lobby.php?member=pws5068 I need a new rewrite to make it look like this: mysite.com/pws5068 Thank you for bearing with my super-long question here. How can I make this happen?

    I'm trying to solve DCG grammar in prolog and succeeded upto a point, i'm stuck in evaluating the expressions involving braces like these. expr( T, [’(’, 5, +, 4, ’)’, *, 7], []), expr(Z) --> num(Z). expr(Z) --> num(X), [+], expr(Y), {Z is X+Y}. expr(Z) --> num(X), [-], expr(Y), {Z is X-Y}. expr(Z) --> num(X), [*], expr(Y), {Z is X*Y}. num(D) --> [D], {number(D)}. eval(L, V, []) :- expr(V, L, []).

  • Using a Resource as an Attribute to a HTML Element in ASP.net

    - by Michael Stum
    I would like to have this piece of code in my .aspx file: <input class="ms-ButtonHeightWidth" type="button" name="BtnOK" id="Button2" value="Close" onclick="javascript:HandleOKButtonClick()" accesskey="<%$Resources:wss,okbutton_accesskey%>" /> Unfortunately, ASP.net doesn't seem to like that: An error occurred during the processing of /_layouts/MyPage/Info.aspx. Literal expressions like '<%$Resources:wss,okbutton_accesskey%>' are not allowed. Use <asp:Literal runat="server" Text="<%$Resources:wss,okbutton_accesskey%>" /> instead That doesn't work in this situation as that would mean nesting the Literal between the quotes of the accesskey attribute, which causes a "The tag contains duplicate 'ID' attributes" error. Is there a way to use a string from a resource without having to change the input to an asp:Button? I guess there has to be a way using <%=, but I don't know how I would address the resource itself?

  • Regex for Searching for Text Not Preceeded By a Specific String

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

    I want to evaluate one expression in C++. To evaluate it, I want the expression to be converted to prefix format. Here is an example wstring expression = "Feature1 And Feature2"; Here are possible ways. expression = "Feature1 And (Feature2 Or Feature3)"; expression = "Not Feature1 Or Feature3"; Here And, Or, Not are reserved words and parentheses ("(", )) are used for scope Not has higher precedence And is set next precedence to Not Or is set to next precedence to And WHITE SPACE used for delimiter. Expression has no other elements like TAB, NEWLINE I don't need arithmetic expressions. I can do the evaluation but can somebody help me to convert the strings to prefix notation?

  • Anonymous types based in Interface

    - by Bhaskar
    Can I create anonymous implementations of an interface , in a way similar to the way delegate() { // type impl here , but not implementing any interface} Something on the lines of new IInterface() { // interface methods impl here } The situations where I see them to be useful are for specifying method parameters which are interface types, and where creating a class type is too much code. For example , consider like this : public void RunTest() { Cleanup(delegate() { return "hello from anonymous type"; }); } private void Cleanup(GetString obj) { Console.WriteLine("str from delegate " + obj()); } delegate string GetString(); how would this be achieved if in the above code , the method Cleanup had an interface as a parameter , without writing a class definition ? ( I think Java allows expressions like new Interface() ... )

  • Split string on non-alphanumerics in PHP? Is it possible with php's native function?

    - by Jehanzeb.Malik
    I was trying to split a string on non-alphanumeric characters or simple put I want to split words. The approach that immediately came to my mind is to use regular expressions. Example: $string = 'php_php-php php'; $splitArr = preg_split('/[^a-z0-9]/i', $string); But there are two problems that I see with this approach. It is not a native php function, and is totally dependent on the PCRE Library running on server. An equally important problem is that what if I have punctuation in a word Example: $string = 'U.S.A-men's-vote'; $splitArr = preg_split('/[^a-z0-9]/i', $string); Now this will spilt the string as [{U}{S}{A}{men}{s}{vote}] But I want it as [{U.S.A}{men's}{vote}] So my question is that: How can we split them according to words? Is there a possibility to do it with php native function or in some other way where we are not dependent? Regards

  • How would you parse the location text from Twitter to get the latitude/longitude in Objective-C?

    - by Brennan
    The location text from Twitter could be just about anything. Sometimes Twitter clients set the location with the user's latitude and longitude in the following format. "\U00dcT: 43.05948,-87.908409" Since there is no built-in support for Regular Expressions in Objective-C I am considering using the NSString functions like rangeOfString to pull the float values out of this string. For my current purpose I know the values with start with 43 and 87 so I can key off those values this time but I would prefer to do better than that. What would you do to parse the latitude/longitude from this string?

  • problems with url and email regex when searching text

    - by Grant Collins
    Hi, I'm having problems with regular expressions that I got from regexlib. I am trying to do a preg_replace() on a some text and want to replace/remove email addresses and URLs (http/https/ftp). The code that I am have is: $sanitiseRegex = array( 'email' => /'^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/', 'http' => '/^(http|https|ftp)\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*$/', ); $replace = array( 'xxxxx', 'xxxxx' ); $sanitisedText = preg_replace($sanitiseRegex, $replace, $text); However I am getting the following error: Unknown modifier '/' and $sanitisedText is null. Can anyone see the problem with what I am doing or why the regex is failing? Thanks

  • Regex and unicode

    - by dbr
    I have a script that parses the filenames of TV episodes (show.name.s01e02.avi for example), grabs the episode name (from the www.thetvdb.com API) and automatically renames them into something nicer (Show Name - [01x02].avi) The script works fine, that is until you try and use it on files that have Unicode show-names (something I never really thought about, since all the files I have are English, so mostly pretty-much all fall within [a-zA-Z0-9'\-]) How can I allow the regular expressions to match accented characters and the likes? Currently the regex's config section looks like.. config['valid_filename_chars'] = """0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@£$%^&*()_+=-[]{}"'.,<>`~? """ config['valid_filename_chars_regex'] = re.escape(config['valid_filename_chars']) config['name_parse'] = [ # foo_[s01]_[e01] re.compile('''^([%s]+?)[ \._\-]\[[Ss]([0-9]+?)\]_\[[Ee]([0-9]+?)\]?[^\\/]*$'''% (config['valid_filename_chars_regex'])), # foo.1x09* re.compile('''^([%s]+?)[ \._\-]\[?([0-9]+)x([0-9]+)[^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.s01.e01, foo.s01_e01 re.compile('''^([%s]+?)[ \._\-][Ss]([0-9]+)[\.\- ]?[Ee]([0-9]+)[^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.103* re.compile('''^([%s]+)[ \._\-]([0-9]{1})([0-9]{2})[\._ -][^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.0103* re.compile('''^([%s]+)[ \._\-]([0-9]{2})([0-9]{2,3})[\._ -][^\\/]*$''' % (config['valid_filename_chars_regex'])), ]

  • How do I programmatically set property of control in aspx file ?

    - by Thomas Wanner
    This may be a very dumb question but I can't seem to get it working. I use at many places the following syntax for dynamically binding a property of a control in aspx file to the resource entry, e.g. <SomeFunnyControl Text="<%$ Resources : ResClass, ResEntry %>" /> I want to do a similar thing with a class containing some constants, something like <SomeFunnyControl Text="<%= MyConstantsClass.MyStringConstant %>" /> But this doesn't seem to work, it simply sets the text to the exact expression without evaluating it. I am using ASP.NET 3.5 btw. I have tried the databinding approach but I get an HttpParseException saying Databinding expressions are only supported on objects that have a DataBinding event.

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

  • does a switch idiom make sense in this case?

    - by the ungoverned
    I'm writing a parser/handler for a network protocol; the protocol is predefined and I am writing an adapter, in python. In the process of decoding the incoming messages, I've been considering using the idiom I've seen suggested elsewhere for "switch" in python: use a hash table whose keys are the field you want to match on (a string in this case) and whose values are callable expressions: self.switchTab = { 'N': self.handleN, 'M': self.handleM, ... } Where self.handleN, etc., are methods on the current class. The actual switch looks like this: self.switchTab[selector]() According to some profiling I've done with cProfile (and Python 2.5.2) this is actually a little bit faster than a chain of if..elif... statements. My question is, do folks think this is a reasonable choice? I can't imagine that re-framing this in terms of objects and polymorphism would be as fast, and I think the code looks reasonably clear to a reader.

  • Effecient data structure design

    - by Sway
    Hi there, I need to match a series of user inputed words against a large dictionary of words (to ensure the entered value exists). So if the user entered: "orange" it should match an entry "orange' in the dictionary. Now the catch is that the user can also enter a wildcard or series of wildcard characters like say "or__ge" which would also match "orange" The key requirements are: * this should be as fast as possible. * use the smallest amount of memory to achieve it. If the size of the word list was small I could use a string containing all the words and use regular expressions. however given that the word list could contain potentially hundreds of thousands of enteries I'm assuming this wouldn't work. So is some sort of 'tree' be the way to go for this...? Any thoughts or suggestions on this would be totally appreciated! Thanks in advance, Matt

  • Regex expression with leading zero

    - by user1874087
    I'm rather new to regex expressions and need help with a simple expression. I'm using Pentaho for ETL (Replace in String transformation) and I have column values that I need to add leading zeros to and parse out text as part of the database import. So far I have been unable to add the leading zero. The column is called Region and the values are "region 8", "region 10", "region 11". My regex expression is ['Region'] which will eliminate the region text but produces results = "8", "10", "11". I need values to produce "08", "10", "11". So all the single digit numbers must have leading zeros.

  • Sql Server Where Case Then Is Null Else Is Not Null

    - by Fabio Montezuma
    I have a procedure which receive a bit variable called @FL_FINALIZADA. If it is null or false I want to restrict my select to show only the rows that contain null DT_FINALIZACAO values. Otherwise I want to show the rows containing not null DT_FINALIZACAO values. Something like this: SELECT * FROM ... WHERE ... AND (OPE.DT_FINALIZACAO = CASE WHEN (@FL_FINALIZADA <> 1) THEN NULL END OR OPE.DT_FINALIZACAO IS NOT NULL) In this case I receive the message: None of the result expressions in a CASE specification can be NULL. How can I achieve this? Thanks in advance.
