Re: [xml] XPathObject and user/user2


just for your information

I indeed didn't need to communicate the XPathObject to the outside,
therefore I don't need all those ugly hacks anymore .)

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.

   Seems unlikely unless it also uses XSLT with the same objects,

with a pointer to PHP objects is likely to make a lot of damages !
And this is part of xmlXPathFreeObject(), so this hack looks really really

I feared that... It looks like I have to rewrite this XPath stuff then,
since there are unfortunately no _private members in those structs.

  user2 might be safer
I have a hard time understanding why you need to store pointer in the 
XPath objects, In the XPath evaluation context that's understandable,
but in the core objects, I can't understand.

Mmmmh, the main code of PHP libxml2 extension is not by me, so I have to
check this stuff more thoroughly and look, if we really need it. 

I'll report later, what I found :)
