xml - What browsers support Xpath 2.0?

Question

I have recently been working with XPath and have been searching for information on which browsers support XPath 2.0 without much luck. The best I could find was the query technologies comparison table of various rendering engines.

This clearly tells me that Firefox and IE (all versions of both) do not support XPath 2.0, but what about the other rendering engines for Chrome, Safari, etc.? Does anybody have any information on this or know where one can find it?

Answer 1

I do not know of any, and the official list of implementations doesn't include one either.

An alternative - of course less performant than a native implementation - would be XQIB which is an XQuery implementation in JavaScript. XPath 2.0 is fully included as a subset in XQuery 1.0, so you will be able to use all XPath 2.0 features (and more) in all browsers with JavaScript support.

A short sample taken from their website on how to use it:

<script type="text/javascript" src="mxqueryjs/mxqueryjs.nocache.js"></script>
<script type="application/xquery">
  b:alert(
    let $x := <a><b>2</b><c>4</c></a>
    return xs:string($x/b * $x/c)
  )
</script>
