• Best way to get all digits from a string with regex

  - by Chris Marisic

  Is there any better way to get take a string such as "(123) 455-2344" and get "1234552344" from it than doing this: var matches = Regex.Matches(input, @"[0-9]+", RegexOptions.Compiled); return String.Join(string.Empty, matches.Cast<Match>() .Select(x => x.Value).ToArray()); Perhaps a regex pattern that can do it in a single match? I couldn't seem to create one to achieve that though.

• perl regex escape characters

  - by freshWoWer

  I have heard perl is a good language at doing regex but i am a bit confused at the characters that requires escaping I tested the code on http://regexlib.com/RETester.aspx and got the result I want //home/dev/abc/code/hello/world.cpp#1 //home/dev/((.*?)/[^/]+).*# Match $1 $2 //home/dev/abc/code/hello/world.cpp# abc/code abc However, I am not quite sure how do i translate this to perl code I tried, \/\/home\/dev\/\(\(\.\*\?\)\/\[\^\/\]\+\)\.\*\# and \/\/home\/dev\/((.*?)\/[^\/]+).*\# and both failed Don't you think the escaping makes the regex very unreadable? Am i using something wrong?

• Javascript regex hangs (using v8)

  - by Engwan

  Im using this regex to get the contents of a tag in a file. var regex = new RegExp("<tag:main>((?:.|\\s)*)</tag:main>"); This causes the v8 engine to hang indefinitely. Now, if I use new RegExp("<tag:main>([\s\S]*)</tag:main>"), all is good. Anyone have an idea why the first one takes too long?

• Validating XML using XSD with regex pattern

  - by Steel Plume

  Hello, I am parsing a XML file against a XSD containing some regex patterns used for checking input data, but only this regex generates an error, even if it passes into the Eclipse XSD plugin: InvalidRegex: Pattern value '(((com|it|org)\.)+(\b[a-z]+[.]{1}\b)+)?[A-Z]{1}[A-Za-z]+' is not a valid regular expression. The reported error was: 'This expression is not supported in the current option setting.'. So, with SAX validator where can I find the fatal "current option setting"?

• C# regex to validate "realistic" IP values

  - by Joshua

  Regex that somewhat validates if a value has one of the following characteristics: 123-29-123-123.subdomain.zomg.com:8085 123.12.34.56:420 Unfortunately, I'm terrible at Regex, C#, google searches, and the differences between proper nouns and regular ones. It can be a lose approximation, in fact I would go with anything that has a : colon separator with a port after it.

• Converting regex statment for sentance extraction to Ruby

  - by DavidP6

  I found this regex statement on the wiki (http://en.wikipedia.org/wiki/Sentence_boundary_disambiguation) for Sentence boundary disambiguation, but am not able to use it in a Ruby split statment. I'm not too good with regex so maybe I am missing something? This is statment: ((?<=[a-z0-9)][.?!])|(?<=[a-z0-9][.?!]\"))(\s|\r\n)(?=\"?[A-Z]) and this is what I tried in Ruby, but no go: text.split("((?<=[a-z0-9)][.?!])|(?<=[a-z0-9][.?!]\"))(\s|\r\n)(?=\"?[A-Z])")
