Re: [xml] controlling xpath streaming

["Oleg A. Paraschenko" <olpa xmlhack ru>]

  Hello Daniel,

  thank you very much for the suggestion. I've updated the very latest
xpath.c from CVS. Now my application works without problems. It seems
that this patch helped a lot:

$ diff xpath.c xpath.c.r1.288 
11303c11303
<      namespaces = xmlMalloc(2 * (ctxt->nsNr + 1) * sizeof(xmlChar*));
---
>      namespaces = xmlMalloc(2 * (ctxt->nsNr + 1));
