Does libxml2 support XPath 2.0 or not?

Question

I've tried to use the XPath 2.0 exp //span/string(.) in libxml2, but it doesn't work.
So, my question is: does libxml2 support XPath 2.0 or not?

Answer 1

According to this 2007 email from the maintainer of libxml2, libxml2 does not, and will not, support XPath 2.0.

Answer 2

As far as I know -- not. The prevailing majority of XPath 2.0 implementations are part of XSLT 2.0 processors or XQuery processors.
