I can't get contains to work on a href

Mar 9, 2010 2:40am

I'm on an full page ad I want to skip - there's this link:

<a href="http://www.newsfactor.com/news/Panasonic--Best-Buy-To-Push-3-D-TV/story.xhtml?story_id=0200029Q08EG&full_skip=1"><!--b-->Go Directly to NewsFactor.com<!--/b--></a>

_____________________

// #1 using the text of the link
3-D-TV%2Fstory.xhtml%3Fstory_id%3D0200029Q08EG
var input = document.evaluate('//a[contains(.,"Go Directly to NewsFactor.com")]',document,null,XPathResult.FIRST_ORDERED_NODE_TYPE,null).singleNodeValue;
if (input) {
	location.href = input.href
}

Result - success.

_____________________

// #2 using the href
var input = document.evaluate('//a[@href[contains(.,"&full_skip=1")]]',document,null,XPathResult.FIRST_ORDERED_NODE_TYPE,null).singleNodeValue;
if (input) {
	location.href = input.href
}

Result - failure. Why doesn't it work?

Shouldn't it be this?:

var input = document.evaluate('//a[contains(@href,"&full_skip=1")]',
                              document,
                              null,
                              XPathResult.FIRST_ORDERED_NODE_TYPE,
                              null).
                     singleNodeValue;
if (input) {
    location.href = input.href
}

u checking the link text not @href

also remember, that & symbol might be & but it shows up in firebug as &
ive tried to match hrefs by only using firebug, and i would use regex like /&something=(.*)/ but actually the & was & so i had to use /(?:&|&)something=(.*)/

& and & - oops. Okay.

u checking the link text not @href

I still don't know how to check the href.

I also don't know how to use an regex after document.evaluate

Have a look at my post above :p

You can't use Regexp inside a XPath expression, you can only loop over the resulting elements and compare things like .href and .textContent against a regexp

Oops, again. My mind is empty today - and not in the good zen-like way.
