  • Regex and PHP for extracting contents between tags with several line breaks

    - by John
    How can I extract the content between tags with several line breaks? I'm a newbie to regex, who would like to know how to handle unknown numbers of line break to match my query. Task: Extract content between <div class="test"> and the first closing </div> tag. Original source: <div class="test">optional text<br/> content<br/> <br/> content<br/> ... content<br/><a href="/url/">Hyperlink</a></div></div></div> I've worked out the below regex, /<div class=\"test\">(.*?)<br\/>(.*?)<\/div>/ Just wonder how to match several line breaks using regex. There is DOM for us but I am not familiar with that.

  • Why unsigned int contained negative number

    - by Daziplqa
    Hi All, I am new to C, What I know about unsigned numerics (unsigned short, int and longs), that It contains positive numbers only, but the following simple program successfully assigned a negative number to an unsigned int: 1 /* 2 * ===================================================================================== 3 * 4 * Filename: prog4.c 5 * 6 * ===================================================================================== 7 */ 8 9 #include <stdio.h> 10 11 int main(void){ 12 13 int v1 =0, v2=0; 14 unsigned int sum; 15 16 v1 = 10; 17 v2 = 20; 18 19 sum = v1 - v2; 20 21 printf("The subtraction of %i from %i is %i \n" , v1, v2, sum); 22 23 return 0; 24 } The output is : The subtraction of 10 from 20 is -10

  • What can I access in Androids Native libraries? And How?

    - by Donal Rafferty
    I am completely new to the NDK. I have done a couple of the tutorials including the hello from jni one and another one that calculates the sum of two numbers. They involved using cygwin and the ndk to create the library so file and I have a bit of a grasp on how to insert my own libraries into the libraries layer of Android. I have now been asked to access the native libraries on Android and see what I can use them for. My question is can I do this? The STABLE-APIS.txt document is a bit vague and mentions the following as Stable C++ API's in Android 1.5 cstddef new utility stl_pair.h Does that mean I can access them? If so then how do I go about it? I dont think that following the tutorials I have already done would be any help? Any pointers on how to do this or links to tutorials etc.. would be greatly appreciated

  • Add a custom compiler to XCode 3.2

    - by racha
    I have a working gcc 4.3.3 toolchain for an ARM Cortex-m3 and would like to integrate it into XCode. Is there a way to set up XCode (3.2) to use this gcc toolchain instead of the built-in GCC 4.2? What I've tried so far: I've added a modified copy of the GCC 4.2.xcplugin and changed the name, version and executable path. It shows up in XCode but whenever I set the "C/C++ Compiler Version" to the custom compiler it fails with Invalid value '4.3.3' for GCC_VERSION It seems like the valid version numbers are hardcoded somewhere else because even when I remove the original GCC 4.2.xcplugin, the value 4.2 remains valid (but is not visible in the "C/C++ Compiler Version" drop down anymore).

  • ruby on rails, searchlogic and refactoring

    - by JohnMerlino
    Hey all, I'mt not too familiar with searchlogic plugin for rails (I did view the railscasts but wasn't helpful in relation to the specific code below). Can anyone briefly describe how it is being used in the three methods below?

  • PHP: Alternative to SESSIONS

    - by iamjonesy
    Hi, I have a PHP application that relies on session variables quite a lot. After login the user get redirected to a page that executes code to set up a load of session variables depending on who the user is. The application is using data from different sources and the sessions are used to store ID numbers to query the databases. So when the user goes to a page that will query their asset management system their ID for that particular database is called via the session. I've had a LOT of problems with session variables recently. Sometimes only one session file is created during the lifetime of the app, and sometimes each session request results in a new session id (still haven't managed to find out why!). My question is this. Is there an alternative to using session variables for this? Like globals or some other way? Any help most appreciated! Regards, Jonesy

  • Python Random Question

    - by coson
    Good Day, I am using Python 2.6 and am trying to run a simple random number generator program (random.py): import random for i in range(5): # random float: 0.0 <= number < 1.0 print random.random(), # random float: 10 <= number < 20 print random.uniform(10, 20), # random integer: 100 <= number <= 1000 print random.randint(100, 1000), # random integer: even numbers in 100 <= number < 1000 print random.randrange(100, 1000, 2) I'm now receiving the following error: C:\Users\Developer\Documents\PythonDemo>python random.py Traceback (most recent call last): File "random.py", line 3, in <module> import random File "C:\Users\Developer\Documents\PythonDemo\random.py", line 8, in <module> print random.random(), TypeError: 'module' object is not callable C:\Users\Developer\Documents\PythonDemo> I've looked at the Python docs and this version of Python supports random. Is there something else I'm missing? TIA, coson

  • Higher than high-level web frameworks or CMS's?

    - by Ben
    I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

  • Are government programming jobs good?

    - by Absolute0
    I am a passionate software developer and greatly enjoy programming. However I was recently contacted regarding a developer lead position for a government job at NYC for the fire department. The pay is pretty good, and I would assume the position has good job security and stability. But I am hesitant to even go for an interview as it seems like an exaggerated version of Office Space with a lot of Bureaucracy and mindless paper work. The description is as follows: The Lead Applications Developer, supporting the Programming Group, will be responsible for all phases of the system development life cycle including performing system analysis, requirements definition, database design, preparation of scopes of work, and development of project plans. Supervise programming staff and manage projects involving the design, implementation, maintenance, and enhancement of complex Oracle based user applications using Oracle Development tools. Applications will be deployed using Oracle Application Server utilizing programming languages such as JAVA, JSF, JSP, Oracle ADF, PL/SQL, and XML with J2EE and EJB technology. Anyone with previous government experience can share their two cents on this? Thank you.

  • how to profile silverlight mvvm application with a lot of custom controls

    - by tomo
    There is a quite big LOB silverlight application and we wrote a lot of custom controls which are rather heavy in drawing. All data is loaded by RIA service, processed and bound (using INofityPropertyChanged interface) to the view. The problem is that first drawing takes a lot time. Following calls to the service (server) and redrawing is quite fast. I used Equatec profiler to track the problem. I saw that processing takes a couple of miliseconds only so my idea is that the drawing by SL engine is slow. I'm wondering if it is possible to profile somehow processes inside SL to check which drawing operations are taking too much time. Are there any guidelines how to implement faster drawing of complex custom controls?

  • strchr in objective C?

    - by Brian Postow
    I'm trying to write the equivalent of strchr, but with NSStrings... I've currently got this: Boolean nsstrchr(NSString* s, char c) { NSString *tmps = [NSString stringWithFormat: @"%c", c]; NSCharacterSet *cSet = [NSCharacterSet characterSetWithCharactersInString: tmps]; NSRange rg = [s rangeOfCharacterFromSet: cSet]; return rg.location != NSNotFound; } This seems needlessly complex... Is there a way to do this (preferably, one that doesn't involve turning the NSString into a cstring which doubles the run time, or writing it myself using characterAtIndex:... Am I missing some obvious method in the NSString description?

  • Is there an extensible SQL like query language that is safe for exposing via a public API?

    - by Lokkju
    I want to expose some spatial (and a few non-spatial) datasets via a public API. The backend store will either be PostgreSQL/PostGIS, sqlite/spatialite, or CouchDB/GeoCouch. My goal is to find a some, preferably standard, way to allow people to make complex spatial queries against the data. I would like it to be a simple GET based request. The idea is to allow safe SQL type queries, without allowing unsafe ones. I would rather modify something that is off the shelf than doing the entire thing myself. I specifically want to support requesting specific fields from a table; joining results; and spatial functions that are already implemented by the underlying datastore. Ideas anyone?

  • Using SharePoint user profiles to build a company phone directory

    - by Jonathan
    I'm working on a Sharepoint 2007 (MOSS Std) intranet implementation right now, and one of the things we'd like to do is replace the manually-maintained phone directory with the profile information we're importing from AD. People search is great, but I want to have a big page with all the names and phone numbers of the 150 or so people that work at the company (which means using the People Search webpart with a query hard-coded to return everyone won't work). A few quick searches haven't turned up anything, but this seems like a really common request. Can anyone help me out? I'm not opposed to buying a reasonably-priced webpart to solve this or writing some custom code, but both seem like they shouldn't be required for such a simple request.

  • How to keep views free of authorization logic in mvc?

    - by David Lay
    I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?

  • Navigate touch-tone menus via modem

    - by Kongress
    I have a system that I need to programmatically interface with that requires a set of numbers to be dialed after the phone line is picked up, like a standard automated phone answering system. For instance, dial the number 123-456-7890, wait for the line to be answered, wait 15 seconds for the voice prompt, dial 1234#, hang up. The question is, can I and how do I do that through a modem? I know how to dial a number through a modem, it's simply ATDT[phone number], but that will attempt to initiate a data connection which will not allow touch-tone number entry. Would a voice modem provide the necessary capability? If so, could anyone provide example commands to accomplish this?

  • Staging database good practices

    - by Tom
    Hi, I'm about to deploy to production a fairly complex site and for the first time need a staging environment where I can test things in a more realistic environment, especially with regard to some external services that cannot be run locally. My general plan is to develop & test first locally, push simple changes (small bug fixes, HTML/CSS, JS, etc) direct to production, and for larger changes, push first to staging subdomain for thorough testing and then to production. I don't think that I need to keep the staging and production databases in sync (occasional manual updating would do) but I'm wondering if there are any general good practices with regard to maintaing a staging environment in relation to a production environment, especially when it comes to databases. Any general thoughts/advice/experience would be appreciated.

  • Calculating a range of an exact number of values in Python

    - by Einar
    Hello, I'm building a range between two numbers (floats) and I'd like this range to be of an exact fixed length (no more, no less). range and arange work with steps, instead. To put things into pseudo Python, this is what I'd like to achieve: start_value = -7.5 end_value = 0.1 my_range = my_range_function(star_value, end_value, length=6) print my_range [-7.50,-5.98,-4.46,-2.94,-1.42,0.10] This is essentially equivalent to the R function seq which can specify a sequence of a given length. Is this possible in Python? Thanks.

  • Pass elements of a list as arguments to a function in python

    - by Wilduck
    I'm building a simple interpreter in python and I'm having trouble handling differing numbers of arguments to my functions. My current method is to get a list of the commands/arguments as follows. args = str(raw_input('>> ')).split() com = args.pop(0) Then to execute com, I check to see if it is in my dictionary of command- code mappings and if it is I call the function I have stored there. For a command with no arguments, this would look like: commands[com]() However, if a command had multiple arguments, I would want this: commands[com](args[0],args[1]) Is there some trick where I could pass some (or all) of the elements of my arg list to the function that I'm trying to call? Or is there a better way of implementing this without having to use python's cmd class?

  • PyQt: How to keep QTreeView nodes correctly expanded after a sort

    - by taynaron
    I'm writing a simple test program using QTreeModel and QTreeView for a more complex project later on. In this simple program, I have data in groups which may be contracted or expanded, as one would expect in a QTreeView. The data may also be sorted by the various data columns (QTreeView.setSortingEnabled is True). Each tree item is a list of data, so the sort function implemented in the TreeModel class uses the built-in python list sort: self.layoutAboutToBeChanged.emit() self.rootItem.childItems.sort(key=lambda x: x.itemData[col], reverse=order) for item in self.rootItem.childItems: item.childItems.sort(key=lambda x: x.itemData[col], reverse=order) self.layoutChanged.emit() The problem is that whenever I change the sorting of the root's child items (the tree is only 2 levels deep, so this is the only level with children) the nodes aren't necessarily expanded as they were before. If I change the sorting back without expanding or collapsing anything, the nodes are expanded as before the sorting change. Can anyone explain to me what I'm doing wrong? I suspect it's something with not properly reassigning QModelIndex with the sorted nodes, but I'm not sure.

  • What to look for in estimating a PowerBuilder Conversion Project?

    - by tekiegreg
    Hi there, I've been trying to do a spec for a PowerBuilder 9 to 11.5 migration of a relatively complex application. Granted PowerBuilder is not really my specialty I'm having issues trying to justify an estimate for this part of the project (and the PowerBuilder people I've been talking with have had some personal issues lately and are out of communication). These are some of the metrics that we have seen and can evaluate: -PBL Files -Main Windows -Data Windows -Functions (no we don't have the source available on this project) What metrics in particular are helpful and how long would any given "unit" such as a Data Window take?

  • Junit vs TestNG

    - by Sam Merrell
    At work we are currently still using Junit3 to run our tests. We have been considering switching over to Junit4 for new tests being written but I have been keeping an eye on TestNG for a while now. What experiences have you all had with either Junit4 or TestNG and which seems to work better for very large numbers of tests. Having flexibility in writing tests is also important to us since our functional tests cover a wide aspect and need to be written in a variety of ways to get results. Old tests will not be re-written as they do their job just fine. What I would like to see in new tests though is flexibility in the way the test can be written, natural assertions, grouping, and easily distributed test executions.

  • How do I make "simple" throughput servlet-filter?

    - by Tommy
    I'm looking to create a filter that can give me two things: number of request pr minute, and average responsetime pr minute. I already got the individual readings, I'm just not sure how to add them up. My filter captures every request, and it records the time each request takes: public void doFilter(ServletRequest request, ...() { long start = System.currentTimeMillis(); chain.doFilter(request, response); long stop = System.currentTimeMillis(); String time = Util.getTimeDifferenceInSec(start, stop); } This information will be used to create some pretty Google Chart charts. I don't want to store the data in any database. Just a way to get current numbers out when requested As this is a high volume application; low overhead is essential. I'm assuming my applicationserver doesn't provide this information.

  • convert string to float without silent NaN/Inf conversion

    - by Peter Hansen
    I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf'. Before 2.6, float("NaN") would raise a ValueError. Now it returns a float for which math.isnan() returns True, which is not useful behaviour for my application. Here's what I've got at the moment: import math def get_floats(source): for text in source.split(): try: val = float(text) if math.isnan(val) or math.isinf(val): raise ValueError yield val except ValueError: pass This is a generator, which I can supply with strings containing whitespace-separated sequences representing real numbers. I'd like it to yield only those fields which are purely numeric representations of floats, as in "1.23" or "-34e6", but not for example "NaN" or "-Inf". Test case: assert list(get_floats('1.23 -34e6 NaN -Inf')) == [1.23, -34000000.0] Please suggest alternatives you consider more elegant, even if they involve "look before you leap" (which is normally considered a lesser approach in Python).
