[xml] XPath functions

[Matt Bucknall <matt_bucknall yahoo co uk>]

Hi,

Sorry if this is a stupid question, I'm quite new to XSLT and XPath. I am using libxml & libxslt in an application which would benefit from being able to use XPath functions such as upper-case() and year-from-dateTime(). Whilst it would appear libxml supports some functions such as concat(), others seem to be missing (or am I missing something?)

Just out of interest, what versions of XPath and XSLT do libxml/libxslt currently comply with?

Thanks,
Matt.
