Clicking link with WWW::Mechanize

Peter Szinek

3/28/2007 10:44:00 AM

Hello,

I wuold like to click on a link in WWW::Mechaznie, and I know only the
Hpricot XPath of the element I would like to click, nothing more. While
it's certainly possible to look up the text of the element pointed to by
the XPath, there can be more elements with that text, but only one
element with that XPath.

Is this possible with Mechanize somehow?


Thanks,
Peter

Yes, this is possible. Mechanize can click an hpricot element, as long
as it has an 'href', or a 'src' attribute. For example:

page = mech.get('http://example...)
new_page = mech.click((page/'//some/xpath/a'))

If you've got more questions, don't forget about the mechanize mailing
list:

Hope that helps!

Ray is a classic usenet zoo monkey. Liars, once they have been
exposed, frequently revert to behavior most similar to a zoo monkey
who sits in the cage throwing feces at passersby but saying nothing of
value. Note that when you reply to a Proven Liar you encourage them
to continue lying.

LIAR!!!!!!!!!!!!!!!!!!!

"When discussing the concept that all potential solutions ought to ?be
on the table? or that he ?won?t rule anything in our out,? he has
always emphasized that any potential solution must be looked at
through the prism of jobs and whether those proposed solutions would
strengthen the economy. Obviously, tax increases wouldn?t make that
list." Ways and Means Committee spokesperson for Ways and Means
Committee chairman Rep. Dave Camp (R-Mich.).

Bush and Cheney knew they were lying about the WMD.

He probably can't help it. Perhaps he has pellagra.
