I'm a total regex noob and have been struggling with this problem for a while today. I have some content with urls in them. I'd like to simply extract these urls but I am having trouble selecting up to the end of the url.  I have a code sample here:   As you can see it doesn't select correctly, and the last url is not selected at all. Terrible :/  If anyone could steer me in the right direction I would really appreciate it  Update:  To not depend on the above link alone I thought I'd add the regex here as well. Here is the original regex for this question:  /(?:http|ftp)s?:\/\/\S*\.\S*(?="|&lt;)/gi  Here is the content I am testing with:  Here is some content and url &lt;p&gt;http://www.something.com/index.html&lt;/p&gt; &lt;p&gt;Some more content &lt;a href="http://www.something.com/some/path/here.html"&gt;http://www.something.com/some/path/here.html&lt;/a&gt;&lt;/p&gt; Some more text http://www.something.com/something/somethingelse.html content  continued...

How can I get the start and end positions of all matches using the re module? For example given the pattern r'[a-z]' and the string 'a1b2c3d4' I'd want to get the positions where it finds each letter. Ideally, I'd like to get the text of the match back too.

I need to write a function that receives a string and a regex. I need to check if there is a match and return the start and end location of a match. (The regex was already compiled by qr//.)  The function might also receive a "global" flag and then I need to return the (start,end) pairs of all the matches.  I cannot change the regex, not even add () around it as the user might use () and \1. Maybe I can use (?:).  Example: given "ababab" and the regex qr/ab/, in the global case I need to get back 3 pairs of (start, end).

I am currently defining regular expressions in order to capture parameters in a URL, as described in the tutorial. How do I access parameters from the URL as part the HttpRequest object? My HttpRequest.GET currently returns an empty QueryDict object. I'd like to learn how to do this without a library, so I can get to know Django better.

I have a string User name (sales) and I want to extract the text between the brackets, how would I do this?   I suspect sub-string but I can't work out how to read until the closing bracket, the length of text will vary.

I have this gigantic ugly string: J0000000: Transaction A0001401 started on 8/22/2008 9:49:29 AM J0000010: Project name: E:\foo.pf J0000011: Job name: MBiek Direct Mail Test J0000020: Document 1 - Completed successfully  I'm trying to extract pieces from it using regex. In this case, I want to grab everything after Project Name up to the part where it says J0000011: (the 11 is going to be a different number every time). Here's the regex I've been playing with: Project name:\s+(.*)\s+J[0-9]{7}:  The problem is that it doesn't stop until it hits the J0000020: at the end. How do I make the regex stop at the first occurrence of J[0-9]{7}?

I'm trying to scrape data from a website for research.  The urls are nicely organized in an example.com/x format, with x as an ascending number and all of the pages are structured in the same way. I just need to grab certain headings and a few numbers which are always in the same locations. I'll then need to get this data into structured form for analysis in Excel.  I have used wget before to download pages, but I can't figure out how to grab specific lines of text.  Excel has a feature to grab data from the web (Data->From Web) but from what I can see it only allows me to download tables. Unfortunately, the data I need is not in tables.

I am trying to parse url-encoded strings that are made up of key=value pairs separated by either &amp; or &amp;amp;.   The following will only match the first occurrence, breaking apart the keys and values into separate result elements:  var result = mystring.match(/(?:&amp;|&amp;amp;)?([^=]+)=([^&amp;]+)/)   The results for the string '1111342=Adam%20Franco&amp;348572=Bob%20Jones' would be:  ['1111342', 'Adam%20Franco']   Using the global flag, 'g', will match all occurrences, but only return the fully matched sub-strings, not the separated keys and values:  var result = mystring.match(/(?:&amp;|&amp;amp;)?([^=]+)=([^&amp;]+)/g)   The results for the string '1111342=Adam%20Franco&amp;348572=Bob%20Jones' would be:  ['1111342=Adam%20Franco', '&amp;348572=Bob%20Jones']   While I could split the string on &amp; and break apart each key/value pair individually, is there any way using JavaScript's regular expression support to match multiple occurrences of the pattern /(?:&amp;|&amp;amp;)?([^=]+)=([^&amp;]+)/ similar to PHP's preg_match_all() function?  I'm aiming for some way to get results with the sub-matches separated like:  [['1111342', '348572'], ['Adam%20Franco', 'Bob%20Jones']]   or   [['1111342', 'Adam%20Franco'], ['348572', 'Bob%20Jones']]

I have the following data:  http://example1.com    anchor text 1     http://example2.com    anchor text 2 http://example3.com    anchor text 3       And I would like the output to be:  http://example1.com    anchor text 1    &lt;a href="http://example1.com"&gt;anchor text 1&lt;/a&gt; http://example2.com    anchor text 2    &lt;a href="http://example1.com"&gt;anchor text 2&lt;/a&gt; http://example3.com    anchor text 3    &lt;a href="http://example1.com"&gt;anchor text 3&lt;/a&gt;   I have tried getting the code to substitute cells A1 and B1 in cell C1 like this:  ="&lt;a href="A1"&gt;B1&lt;/a&gt;"   However, I'm getting errors because of the equal sign and double quotes in the HTML code. I have tried using single quotes to escape it, but still no luck.  Anyone know how to do this? Your help is highly appreciated.

I can't seem to find an answer to this problem, and I'm wondering if one exists. Simplified example:  Consider a string "nnnn", where I want to find all matches of "nn" - but also those that overlap with each other. So the regex would provide the following 3 matches:   nnnn nnnn nnnn   I realize this is not exactly what regexes are meant for, but walking the string and parsing this manually seems like an awful lot of code, considering that in reality the matches would have to be done using a pattern, not a literal string.
