• HTML Scraping in Php.

  - by tsellon

  I've been doing some html scraping in PHP using regular expressions. This works, but the result is finicky and fragile. Has anyone used any packages that provide a more robust solution? A config driven solution would be ideal, but I'm not picky.

• asp.net c# ip address lost after postback?

  - by Mark

  Hi all, One of my functions in a class is called GetIpAddress() which returns the following string: System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"] This all works well in regular page loads and gets my ip address, but when i for example let a user place a comment, then the ip address is lost after postback and i get an empty string returned. Am I missing something here maybe? Kind regards, Mark

• Lisp's "some" in Python?

  - by Mark Probst

  I have a list of strings and a list of filters (which are also strings, to be interpreted as regular expressions). I want a list of all the elements in my string list that are accepted by at least one of the filters. Ideally, I'd write [s for s in strings if some (lambda f: re.match (f, s), filters)] where some is defined as def some (pred, list): for x in list: res = pred (x) if res: return res return False Is something like that already available in Python, or is there a more idiomatic way to do this?

• Rewrite URL, regex help...

  - by Tony

  Hello, I am using the following Rewrite URL: RewriteRule /([^/?.]+) /somedir/somefile.aspx\?Name=$1 [NC,L] which works great for my use, but I need to restrict it to only act on text that does not contain a filename... for example, if I use the url www.somedomain.com/SomeName it works fine, but it also fires if I use www.somedomain.com/TestPage.aspx So I am not sure if I need an additional Rewtire rule, or if the current one can be modified to disallow any text with an extension, for example. Any help with this regular expression would be greatly appreciated.

• Unicode Regex; Invalid XML characters

  - by Ambush Commander

  The list of valid XML characters is well known, as defined by the spec it's: #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] My question is whether or not it's possible to make a PCRE regular expression for this (or its inverse) without actually hard-coding the codepoints, by using Unicode general categories. An inverse might be something like [\p{Cc}\p{Cs}\p{Cn}], except that improperly covers linefeeds and tabs and misses some other invalid characters.

• Is there an easy method to combine two relative paths in C# ?

  - by Ioannis

  I want to combine two relative paths in C#. For example: string path1 = "/System/Configuration/Panels/Alpha"; string path2 = "Panels/Alpha/Data"; I want to return string result = "/System/Configuration/Panels/Alpha/Data"; I can implement this by splitting the second array and compare it in a for loop but I was wondering if there is something similar to Path.Combine available or if this can be accomplished with regular expressions or Linq? Thanks

• Automatically copy files without overwriting, but creating numbered ones instead

  - by user1688322

  I need to copy files at a regular interval, eg once an hour so I tried setting up an xcopy batch saying it should copy the files it needs to copy to another folder. Now when it copies, it overwrites the files which is not what it is supposed to do. When a file is copied, it should create a new file instead, named something like File.txt, File-COPY1.txt, File-COPY2.txt or something like that. Any way to do that? Thanks in advance.

• Powder Physics Games

  - by frinkz

  Does anyone have any experience with this sort of thing? I'm talking about applets like this http://dan-ball.jp/en/javagame/dust/ I'm really interested in how they work, it seems more like fluid-dynamics than regular game physics. Does anyone know any open source variations, or any hints on how they might work? I think it would be really fun and challenging to work on something like this, but I'm not sure where to start researching... Thanks :)
