Hi the regex you are using doesnt seem correct [^tr] is any character that is not 't' or not 'r' it doesnt mean not the sequence tr.
Plus if you are getting multiple <tr> instead of 1 that you expect your regex is probably too greedy try replacing .* constructs with .*? or modify the regex In any case XPath is as dependent on HTML structure as a Regex is (e.g. what if you move to a tableless layout) regards deepak On Thu, Nov 19, 2009 at 8:17 AM, rosiere <[email protected]> wrote: > > Hello, > > Thanks for your advice. > > I did applied case insensitive check: like this: > > (?is)<tr\sclass="tgDataLine.*1\)\" >([^tr].*)</tr> > > However I still face problem.
