Can I use xpath 2.0 with firefox and selenium?

Question

I saw other questions referring to xpath 2.0, which apparently simplifies string expressions. I'm using Firefox 3.5.5 and selenium 1.0.1.

• How can I check if my versions of Firefox and Selenium support it?
• Does Selenium defer to Firefox's built-in Xpath implementation?
• In that case, if I start using another (perhaps older) browser with selenium, will I run into problems by expecting xpath 2.0?

Answer 1

By default, selenium uses the "native" version of XPath that comes with the browser. You can make it use a version that comes with Selenium, written in JavaScript. This seems to implement XPath 1.0, based on glancing at the source.
