Re: [xml] XPathObject and user/user2

[Christian Stocker <chregu bitflux ch>]

Hi

just for your information

I indeed didn't need to communicate the XPathObject to the outside,

I'll see what I can do about XPathContext (I assume, I have to dig
further into Zend/PHPs object management..)

Thanks very much for your useful and quick help.
