Asp Forum - Hpricot and XPaths with indices

Hello,

I just started to use HPricot a few days ago (what a cool piece of
software! ;-) so it is possible that I have just overlooked it but I did
not find a way to evaluate XPaths with indices yet. Instead of a general
XPath, e.g.:

(doc/'//div/table/tr/td/img')

I would like to lookup an indexed one:

(doc/'//div[2]/table[3]/tr[2]/td[8]/img[2]').

OK, I guess this is doable by ((doc/'//div)[2]./table)[3]... or
something similar, but is this the only (and accepted) way?

TIA,
Peter

Yay rftdocs. Hpricot's XPath syntax seems quite incomplete, either e.g.
div:eq(0) will work or nothing will.

Very true. And there are plans to enhance:

Unfortunately, I am six days late as of this day. That is frownworthy, I know.
