face="Times New Roman"><span style='font-size:12.0pt'>Okay, I give up. I've
worked on this for over an hour and I need more experienced help. (Web
searches and book references haven't helped either.)<br>
<br>
I have a URL in a string and I'd like to replace part of it but first I need to
find the part that I care about. Here's an example of the string: <br>
<br>
web_url = '<a href="http://foo/bar.html">http://foo/bar.html</a>'<br>
<br>
Now, what I am trying to do is find the *last* forward slash (/) in that string
so that I can then replace everything after it. I am having difficulty
finding that last slash though. <br>
<br>
I am trying to use the str[ regexp, int ] function, but I
can't seem figure it out.<br>
<br>
Can anyone help me with this regexp? Once I get it I'll figure out what's
the best function for what I need to do. Thanks. <br>
<br>
Paul C.<br>
