I'm very poor with regexps but this should be very simple for someone who knows regexps. Basically I will have a string like this: <if>abc <else>xyz I would like a regexp so if the string contains <if> <else>, it splits the string into two parts and returns the two strings after <if> and <else>. In the above example it might return a...

Hi, I have a string which contains the text of an article. This is sprinkled with BBCodes (between square brackets). I need to be able to grab the first say, 200 characters of an article without cutting it off in the middle of a bbcode. So I need an index where it is safe to cut it off. This will give me the article summary. The summa...

I've got a string that I'm trying to split into chunks based on blank lines. Given a string s, I thought I could do this: re.split('(?m)^\s*$', s) This works in some cases: >>> s = 'foo\nbar\n \nbaz' >>> re.split('(?m)^\s*$', s) ['foo\nbar\n', '\nbaz'] But it doesn't work if the line is completely empty: >>> s = 'foo\nbar\n\nbaz'...
Hey guys, I'm trying to select a specific string out of a text, but I'm not a master of regular expressions. I tried one way, and it starts from the string I want but it matches everything after what I want too. My regex: \nSCR((?s).*)(GI|SI)(.*?)\n Text I'm matching on.

Query: barfly london Should match: Camden Barfly, 49 Chalk Farm Road, London, NW1 8AN I've tried many, many regex's for this, but none have worked so far. I am considering that maybe I will need to split the search into two separate qu...
Someone is telling me I need to escape a semicolon in a Perl regular expression literal. That is, to match a line containing a semicolon, I should use /\;/ and not /;/. From what I've read, the semicolon has no special meaning in a regular expression literal, so escaping it seems unnecessary. I've done some experiments and /;/ seems to ...
Got a simple task to get a XPath expression and return a prefix that matches the parent of the node that (might be) selected. Example: /aaa/bbb => /aaa /aaa/bbb/ccc => /aaa/bbb /aaa/bbb/ccc[@x='1' and @y="/aaa[name='z']"] => /aaa/bbb Because the patterns inside the square brackets might contain brackets within quotes, I d...

Hi, I've been trying to do the following: if (m/(foobar)\{2,}?/ig) to process a file and only act on those lines where greater than 2 occurences of 'foobar' are present. Not working - I suspect it may need the "back-referencing" technique, but I'll be pleasantly surprised if someone here can do it with a simple matching technique ...
