Regular expressions again
Hi,
I need to use the Regular Expression Extractor to get some data out from the server response. However, I still have troubles with getting it working properly. The first problem is connected with the "Match No." parameter of RegExtractor - when I set it to 0 or 1 it works just nice. But when I use any other number I get "no match". I'm sure there's more than one occurence of of a string I search for but I can't get to it.
And here goes the second problem - I want to extract all image sources on web page. I use the following pattern to match the "img" tag -> <img.*src="(.*)".*
What I get is either "no match" or a random piece of HTML source code starting on the first image source and continuig randomly ...
Any help would be appreciated
Regards
JBachorik

Ending a regex with .* is guaranteed to match the rest of the page. Try
something like:
<img[^>]*src="([^"]*)"
And buy a book about regular expressions - it's money well spent as regexes
are very complex.
