I've asked earlier about parsing out link text...  To be sure, the example
that Gisle quotes (for the reasons below, I suppose) does not parse this
(real-world and, I believe, perfectly valid) page:

--------------
Elli Angelopoulou's home page <body> <p>This web page uses frames, but your browser doesn't support them.</p> </body> 

--------------

LinkExtor will parse the links if the tag that I specify is not "a" but
"frame", but it cannot parse out the text (it throws it away I suppose).
Any suggestions?
