remove bing links from content sites

Lately, I have seen numerous "bing" links appearing in certain content sites I frequent. A case in point is http://articles.moneycentral.msn.com

It is somewhat insidious as unless I happen to note it is a search link, I pursue it imagining it will take me to some good content.

So I wrote a GreaseMonkey script to disable those links. Here goes:

// ==UserScript==
// @name           test
// @namespace      http://userscripts.org/thushara/
// @include        http://articles.moneycentral.mn.com/*
// ==/UserScript==
var allLinks, thisLink;
allLinks = document.evaluate(
    '//a[@href]',
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);
for (var i = 0; i < allLinks.snapshotLength; i++) {
    thisLink = allLinks.snapshotItem(i);
    // do something with thisLink
    if (thisLink.href.substring(0,19)=="http://www.bing.com") {
      thisLink.removeAttribute("href");
    }
}

I'm not too familiar with XPath, but I believe it is possible to specify "http://www.bing.com" inside the XPath query itself, so that there is no need to iterate through all the links finding the search links. I couldn't get the syntax right for this. Please post if you find a way around this.
