Rather than describe the problems you are having trying to make Hpricot
deliver a particular result, why not say what you are trying to accomplish
and we can discuss that instead?

Parsing and extracting particular text from syntactically correct HTML pages
is relatively easy. It only requires a few lines of Ruby code. You can
choose which tags to extract text from, and leave all the others behind.

In some cases, it is simpler to write your own extraction code than to try
to get a library to do this for you. But this approach requires that the
HTML pages be reasonably error-free -- it doesn't work very well if there
are errors in the syntax of the source pages.

If the pages you have to parse are reasonably error-free, you may have a
much easier time getting what you are after than you may think at this
point.
