Thank you ! Same algorithms, other language. Should be fairly simple =o)

In my searches on internet, i found that Mozilla::Mechanize seems to do this another way. The elements it returns are Mozilla::DOM::HTMLElement, and it gets their position thanks to a QueryInstance.
I don't know what a DOM:HTMLElement are, nor QueryInstance. I don't have the time to learn these now, and know that i want to use WWW::Mechanize::Firefox, so i could as well forget about it for now.

I was just wondering if it was equivalent to using XPath in the end, and if a few words could make me understand.
If not, it's all alright : i now know i should use XPath.
And if i need to understand these, i'll read a book about it.
