xmlXPathNewContext ()

xmlXPathContextPtr xmlXPathNewContext       (xmlDocPtr doc);

Create a new xmlXPathContext

`doc` :	the XML document
Returns :	the xmlXPathContext just allocated.

xmlXPathFreeContext ()

void        xmlXPathFreeContext             (xmlXPathContextPtr ctxt);

Free up an xmlXPathContext

ctxt : the context to free

xmlXPathEval ()

xmlXPathObjectPtr xmlXPathEval              (const xmlChar *str,
                                             xmlXPathContextPtr ctxt);

Evaluate the XPath Location Path in the given context.

`str` :	the XPath expression
`ctxt` :	the XPath context
Returns :	the xmlXPathObjectPtr resulting from the eveluation or NULL. the caller has to free the object.

xmlXPathFreeObject ()

void        xmlXPathFreeObject              (xmlXPathObjectPtr obj);

Free up an xmlXPathObjectPtr object.

obj : the object to free

xmlXPathEvalExpression ()

                                             xmlXPathContextPtr ctxt);

Evaluate the XPath expression in the given context.

`str` :	the XPath expression
`ctxt` :	the XPath context
Returns :	the xmlXPathObjectPtr resulting from the evaluation or NULL. the caller has to free the object.
