Find Version of XPath in Simple XML for PHP

Question

I am working in PHP and using SimpleXML and XPath.
Is there a way to find which version of XPath is included with SimpleXML/PHP?

Also, is the version of XPath used with SimpleXML the "full version" with all of the features as a "non-SimpleXML" version (in particular "fn:sort")?

Thanks for input and leads.

Generally, if the documentation just says "XPath" then it's a reasonable assumption that it's XPath 1.0, because both the software and documentation were written when that was the only version in town. But it's easy to check, e.g. by trying a function like current-date(). If you want a later version, you'll need a third-party library such as (my company's product) SaxonC. — Michael Kay

As stated in the docs, SimpleXML requires libxml

This extension requires the libxml PHP extension

and according to libxml homepage, XPATH 1.0 is the implemented version
