The RE is applied to the whole body (or headers etc), and first finds all the matches. Depending on the match number specified, the appropriate match(es) is/are returned. > Using something like: > > my_unique_string_in_the_line.*(\w+)=(\w+) > > will only match once. > Yes, if the prefix is unique. It might be nice if the RE could operate on a subset of the page, but that's not currently possible. If the page is reasonably well structured, the XPath extractor might be a suitable alternative, as that can search in multiple levels of context. > regards, > > > Tom > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
