  • Converting paragraph tags with RegEx

    - by Joel
    I need to replace all <p> tags with <br /> tags within a string. The problem is that the <p> tag can have attributes in it , such as <p align="center"> so I want to delete all occurrences of an opening tag of a paragraph, no matter what attributes are in it, and replace them with <br />. I am using PHP and had no success getting to the right expression with the preg_replace function. Any help would be appreciated! Joel

  • Convert Json date string to JavaScript date object

    - by dagda1
    Hi, I have the following JSON object which has a date field in the following format: { "AlertDate": "\/Date(1277334000000+0100)\/", "Progress": 1, "ReviewPeriod": 12 } I want to write a regular expression or a function to convert it to a javascript object so that it is in the form: { "AlertDate": "AlertDate":new Date(1277334000000), "Progress": 1, "ReviewPeriod": 12 } The above date format fails validation in the JQuery parseJSON method. I would like to convert the 1277334000000+0100 into the correct number of milliseconds to create the correct date when eval is called after validation. Can anyone help me out with a good approach to solving this? Cheers Paul

  • boost timer usage question

    - by stefita
    I have a really simple question, yet I can't find an answer for it. I guess I am missing something in the usage of the boost timer.hpp. Here is my code, that unfortunately gives me an error message: include <boost/timer.hpp> int main() { boost::timer t; } And the error messages are as follows: /usr/include/boost/timer.hpp: In member function ‘double boost::timer::elapsed_max() const’: /usr/include/boost/timer.hpp:59: error: ‘numeric_limits’ is not a member of ‘std’ /usr/include/boost/timer.hpp:59: error: ‘::max’ has not been declared /usr/include/boost/timer.hpp:59: error: expected primary-expression before ‘double’ /usr/include/boost/timer.hpp:59: error: expected `)' before ‘double’ The used library is boost 1.36 (SUSE 11.1). Thanks in advance!

  • Regexp in iOS to find comments

    - by SteveDolphin23
    I am trying to find and process 'java-style' comments within a string in objective-C. I have a few regex snippets which almost work but I am stuck on one hurdle: different options seem to make the different styles work. For example, I am using this to match: NSArray* matches = [[NSRegularExpression regularExpressionWithPattern:expression options:NSRegularExpressionAnchorsMatchLines error:nil] matchesInString:string options:0 range:searchRange]; The options here allow me successfully find and process single line comments (//) but not multiline (/* */), if I change the option to NSRegularExpressionDotMatchesLineSeparators then I can make multiline work fine but I can't find the 'end' of a single line comment. I suppose really I need dot-matches-line-separators but I need a better way of finding the end of a single line comment? The regexp I have so far are: @"/\\*.*?\\*/" @"//.*$" it's clear to see if dot matches a line separator then the second one (single line) never 'finishes' but how do I fix this? I found some suggestions for single line that were more like: @"(\/\/[^"\n\r]*(?:"[^"\n\r]*"[^"\n\r]*)*[\r\n])" But that doesn't' seem to work at all! Thanks in advance for any pointers.

  • Exclude subexpression from regexec in c++

    - by wyatt
    Suppose I was trying to match the following expression using regex.h in C++, and trying to obtain the subexpressions contained: /^((1|2)|3) (1|2)$/ Suppose it were matched against the string "3 1", the subexpressions would be: "3 1" "3" "1" If, instead it were matched against the string "2 1", the subexpressions would be: "2 1" "2" "2" "1" Which means that, depending on how the first subexpression evaluates, the final one is in a different element in the pmatch array. I realise this particular example is trivial, as I could remove one of the sets of brackets, or grab the last element of the array, but it becomes problematic in more complicated expressions. Suppose all I want are the top-level subexpressions, the ones which aren't subexpressions of other subexpressions. Is there any way to only get them? Or, alternatively, to know how many subexpressions are matched within a subexpression, so that I can traverse the array irrespective of how it evaluates? Thanks

  • Regex for zeroing in on build output text error

    - by Mike Atlas
    I'd like to quickly hone in on what failed in a build log output that is nearly 5k lines long, using Notepad++ as my editor for the file. Notepad++ has the nice ability to specify regular expressions, so I am wondering if there is a way to not match: Compile complete -- 0 errors, 0 warnings but to match, for example: Compile complete -- 1 errors, 0 warnings Compile complete -- 100 errors, 0 warnings where the match would be (1 or more) errors. If this isn't possible, I will probably just write a quick line-by-line parsing tool instead, but I was hoping someone on StackOverflow could whip out a regular expression in the same amount of time - I'm definitely not proficient enough with regular expressions to be able to write one for my needs in a short amount of time.

  • In Silverlight, what structures, aside of the ListBox, can be used for binding?

    - by Aidenn
    I need to simply provide the content of a property to a custom User Control in Silverlight. My control is something like this: <UserControl x:Class="SilverlightApplication.Header" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="300" d:DesignHeight="120"> <Grid x:Name="Header_Layout"> <StackPanel x:Name="hiHeaderContent" Width="Auto" Margin="73,8,8,8"> <TextBlock x:Name="User:" Text="{Binding name}" /> </StackPanel> </Grid> I try to use this User Control from another control where I try to pass the parameter "name" to the previous UserControl ("Header"). I don't need to create a "ListBox" as I will only have 1 header, so I try to avoid doing: <ListBox x:Name="HeaderListBox" Grid.Row="0"> <ListBox.ItemTemplate> <DataTemplate> <SilverlightApplication:Header/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> in order to send the "User" account using: HeaderListBox.ItemsSource = name; Is there any other structure I can use instead of the ListBox to pass the parameter just once? It won't be a list, it's just a header... Thank you!

  • Using Regular Expressions

    - by bebeTech
    I am having problems trying to use the regular expression that I used in JavaScript. On a web page, you may have: <b>Renewal Date:</b> 03 May 2010</td> I just want to be able to pull out the 03 May 2010, remembering that a webpage has more than just the above content. The way I currently perform this using JavaScript is: DateStr = /<b>Renewal Date:<\/b>(.+?)<\/td>/.exec(returnedHTMLPage); I tried to follow some tutorials on java.util.regex.Pattern and java.util.regex.Matcher with no luck. I can't seem to be able to translate (.+?) into something they can understand?? thanks, Noeneel

    I have a table with a schema of Table(number, ref, ref, varchar2, varchar2,...). How would I insert a row of data into this table?

  • How can a class's memory-allocated address be determined from within the contructor?

    - by Jim Fell
    Is it possible to get the memory-allocated address of a newly instantiated class from within that class's constructor during execution of said constructor? I am developing a linked list wherein multiple classes have multiple pointers to like classes. Each time a new class instantiates, it needs to check its parent's list to make sure it is included. If I try to do something like this: MyClass() // contructor { extern MyClass * pParent; for ( int i = 0; i < max; i++ ) { pParent->rels[i] == &MyClass; // error } } I get this error: error C2275: 'namespace::MyClass' : illegal use of this type as an expression Any thoughts or suggestions would be appreciated. Thanks.

  • C# Regex: only letters followed by an optional .

    - by TheDude
    Hello, I am looking for a way to get words out of a sentence. I am pretty far with the following expression: \b([a-zA-Z]+?)\b but there are some occurrences that it counts a word when I want it not to. E.g a word followed by more than one period like "text..". So, in my regex I want to have the period to be at the end of a word zero or one time. Inserting .? did not do the trick, and variations on this have not yielded anything fruitful either. Hope someone can help!

  • Is allocating a dynamic array without specifying size well formed code?

    - by Als
    The following simple program snippet gives compilation errorswith gcc-4.3.4. Program: int main() { char *ptr = new char[10]; char *ptr1 = new char[]; return 0; } Compilation errors: prog.cpp: In function ‘int main()’: prog.cpp:4: error: expected primary-expression before ‘]’ token prog.cpp:3: warning: unused variable ‘ptr’ prog.cpp:4: warning: unused variable ‘ptr1’ But the same compiles cleanly with MSVC without any diagnostic message. So my question is: Does the Standard allow an new [] to be called without specifying the size? Or this a bug in MSVC? Can someone provide a reference from the standard which will conclusively say that the above code example is ill-formed or well-formed? I have had a look at: 5.3.4 New [expr.new] & 18.4.1.2 Array forms [lib.new.delete.array] but couldnt find any conclusive evidence about the behavior.

  • Accessing 'data' argument of with() function?

    - by Ken Williams
    Is it possible, in the expr expression of the with() function, to access the data argument directly? Here's what I mean conceptually: > print(df) result qid f1 f2 f3 -1 1 0.0000 0.1253 0.0000 -1 1 0.0098 0.0000 0.0000 1 1 0.0000 0.0000 0.1941 -1 2 0.0000 0.2863 0.0948 1 2 0.0000 0.0000 0.0000 1 2 0.0000 0.7282 0.9087 > with(df, subset(.data, select=f1:f3)) # Doesn't work Of course the above example is kind of silly, but it would be handy for things like this: with(subset(df, f2>0), foo(qid, vars=subset(.data, select=f1:f3))) I tried to poke around with environment() and parent.frame() etc., but didn't come up with anything that worked. Maybe this is really a question about eval(), since that's how with.default() is implemented.

  • What is wrong with my SQL syntax for an UPDATE with a JOIN?

    - by Phil H
    I have two tables, related by a common key. So TableA has key AID and value Name and TableB has keys AID, BID and values Name, Value: AID Name 74 Alpha AID BID Name Value 74 4 Beta Brilliance I would like to update the TableB Value here from Brilliance to Barmy, using just the Name fields. I thought I could do it via an UPDATE containing a JOIN, but Access (I know...) is complaining with 'Syntax error (missing operator) in query expression ' and then everything from 'Barmy' here: UPDATE tB SET tB.BValue='Barmy' FROM TableB tB INNER JOIN TableA tA ON tB.AID=tA.AID WHERE tB.Name='Beta' AND tA.Name='Alpha'; What is my heinous crime? Or is it just Access not conforming?
