struct GdomeXPathEvaluator {

};

gdome_xpeval_mkref ()

GdomeXPathEvaluator* gdome_xpeval_mkref     (void);

Constructor of the XPathEvaluator interface.

Returns :

the reference to the XPathEvaluator structure.

gdome_xpeval_ref ()

void        gdome_xpeval_ref                (GdomeXPathEvaluator *self,
                                             GdomeException *exc);

Increase the reference count of the XPathEvaluator structure.

`self` :	XPathEvaluator Object ref
`exc` :	Exception Object ref

gdome_xpeval_unref ()

void        gdome_xpeval_unref              (GdomeXPathEvaluator *self,
                                             GdomeException *exc);

Decrease the reference count of the XPathEvaluator. Free the structure if XPathEvaluator will have zero reference.

`self` :	XPathEvaluator Object ref
`exc` :	Exception Object ref

gdome_xpeval_createNSResolver ()

GdomeXPathNSResolver* gdome_xpeval_createNSResolver
                                            (GdomeXPathEvaluator *self,
                                             GdomeNode *nodeResolver,
                                             GdomeException *exc);

Adapts any DOM node to resolve namespaces so that an XPath expression can be easily evaluated relative to the context of the node where it appeared within the document.

`self` :	GdomeXPathEvaluator Object ref
`nodeResolver` :	The node to be used as a context for namespace resolution.
`exc` :	Exception Object ref
Returns :	GdomeXPathNSResolver object.

gdome_xpeval_createResult ()

GdomeXPathResult* gdome_xpeval_createResult (GdomeXPathEvaluator *self,
                                             GdomeException *exc);

`self` :	GdomeXPathEvaluator Object ref
`exc` :	Exception Object ref
Returns :	an GdomeXPathResult object which may be passed as a parameter to the evaluation methods of this GdomeXPathEvaluator so that a new one is not created on each call to an evaluation method.

gdome_xpeval_evaluate ()

GdomeXPathResult* gdome_xpeval_evaluate     (GdomeXPathEvaluator *self,
                                             GdomeDOMString *expression,
                                             GdomeNode *contextNode,
                                             GdomeXPathNSResolver *resolver,
                                             unsigned int type,
                                             GdomeXPathResult *result,
                                             GdomeException *exc);

Evaluates an XPath expression string

`self` :	GdomeXPathEvaluator Object ref
`expression` :	The XPath expression string to be parsed and evaluated.
`contextNode` :	Context node for the evaluation of this XPath expression.
`resolver` :	The resolver permits translation of prefixes within the XPath expression into appropriate namespace URIs.
`type` :	If specified, result will be coerced to return the specified type.
`result` :	Specifies a GdomeXPathResult object to be re-used.
`exc` :	Exception Object ref
Returns :	a result of the specified type if possible.
