But I thought you said that the DOM XML wouldn't parse a normal HTML web
page because 98% of web pages aren't truly XML compatible and the XML parser
would die with an error message(s)?
I want to be able to feed the parser any old HTML web page and read the node
values from the DOM (created by the parser), just like I do with IE and
Javascript.
Thanks
PS: I am learning slowly so don't get tooooo mad with me ;)

What you want has already been done, with two different
approaches: DOM XML functions and Sablotron functions (SAX
interface). Just use one of these modules in your script.
