Re: Global regex giving up too soon

First of all, the /c modifier is meaningless with s///. Had you turned on warnings, Perl would have told you so. Furthermore, the regex matches from the "href" to the final ">", and you replace everything, but the second quote. For the given example string, there's only one "href", so the /g is pointless as well.

I can't figure out what your intention is, so I'm not offering a working regex.

For the given example string, there's only one "href", so the /g is pointless as well. I figured that was my problem. That's why I tried using /c, but I couldn't find a good description of how it worked. So basically, I guess there is no way to get /g to look over the entire regex, so I'll have to use while $& or establish that there's an href earlier so I don't have to use it in the regex. Anyway, thanks for not telling me to use a module!	[reply]

Well, does it make sense that there is a substitution made in more than one iteration of my loop, but if I use the regex alone, there are fewer (only one) substitutions made?	[reply]

thanks for not telling me to use a module But he did tell you (or rather, nudge you) to use warnings, which you blithely ignored. At some point you should step up to the realization that perl (the interpreter) can help you write better, less buggy code. thanks for not telling me to use a module Then I'll do the honors: HTML::Parser HTML::PullParser HTML::TokeParser HTML::LinkExtor HTML::TreeBuilder etc. etc. Ah, here's an interesting thread: How to use Regular Expressions with HTML Please read the whole thread, esp. the replies by Ovid.
