You generaly want to use a HTML parser ... provided that Wuby has one.

You may be lucky with <title> since it's likely to not include any 
attributes, but still there might be some whitespace INSIDE the tags, 
there may be a comment inside the <title>...</title> that you may or may 
not want, there may be a <title> or </title> inside a comment etc. etc. 
etc.

In (censored) I'd use HTML::Parser from CPAN, but shhhh ... this is a 
Wuby site, we don't speak of such things here.
