  • 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.

  • Matching sentences with regex in Java

    - by Gary
    Hi, I'm using the Scanner class in java to go through a a text file and extract each sentence. I'm using the setDelimiter method on my Scanner to the regex: Pattern.compile("[\\w]*[\\.|?|!][\\s]") This currently seems to work, but it leaves the whitespace at the end of the sentence. Is there an easy way to match the whitespace at the end but not include it in the result? I realize this is probably an easy question but I've never used regex before so go easy :)

    Hello everyone. In a Latex Report I am making I have to write a regex. There is only one in the whole report, so I don't really want to use packages and so on.

  • 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])")
