Re: [xml] best way copy of xmlXPathObjectPtr->node

[Mark_Vakoc peoplesoft com]

Something like:

xmlNodeSetPtr doSomething(xmlDocPtr doc, const xmlChar* xpath) {
xmlNodeSetPtr ret = NULL;
xmlXPathObjectPtr obj;
......
obj = xmlXPathEval(xpath,ctxt);
if (obj != NULL && obj->type == XPATH_NODESET) {
  ret = obj->nodesetval;
  obj->nodesetval = NULL;
}
if (obj != NULL)
  xmlXPathFreeObject(obj);
......
return ret;
}

Hey!

I wanted to do a function you give a xmlDocPtr and an XPath expression,
that returns a xmlNodeSetPtr, so you don't have to create any
xmlXPathContextPtr. The problem is, that nodesetval is being free'd,
when I call xmlXPathFreeObject() and I haven't found a function in
libxml2 to copy a xmlNodeSetPtr. Is there a better way to get a copy
beside loop through all the nodes and put them in a new xmlNodeSetPtr
one-by-one?

TIA
Oliver
