| containsregex and concat | containsregex and concat 2006-11-27 - By George Bills
Hrm, it probably isn't since advanced regexs are still black magic to
me. The "." was supposed to match any character, including a newline
(with the s flag), the * to say match 0-n of them and the ? to say be
lazy, match as little as possible (so that I don't pull in
<table>...</table><table>...</table> in one match).
I just tried [^<], but it doesn't seem to work - I think because of such
things as "<table><tr>...</tr></table>" - the opening bracket of <tr>
conflicts. I tried [.<>]*? to make sure that the "regex.body" part
was matching the brackets, but that didn't work either.
Also, <table class="summary"> was wrong - <table class="summary"(.*?)>
is a little better since the tables can have more than the class
attribute (in fact, all of them do). But after changing that I'm
matching the entire document - <html> through to </html>. That might
just be because I'm using filetokenizer - if I make one match within
filetokenizer, do I end up getting the entire document? If so, how do I
get only the matching text?
Regex is now: <table class="summary".*?>.*?</table>
Thanks for the help, I appreciate it.
