The [DOMXPathNSResolver](classDOMXPathNSResolver.html "The DOMXPathNSResolver interface permit prefix strings in the expression to be properly bound to name...") interface permit prefix strings in the expression to be properly bound to namespaceURI strings.
[DOMXPathEvaluator](classDOMXPathEvaluator.html "The evaluation of XPath expressions is provided by DOMXPathEvaluator.") can construct an implementation of [DOMXPathNSResolver](classDOMXPathNSResolver.html "The DOMXPathNSResolver interface permit prefix strings in the expression to be properly bound to name...") from a node, or the interface may be implemented by any application.
Since
DOM Level 3
| DOMXPathNSResolver::DOMXPathNSResolver ( ) | protected |
|---|
◆ ~DOMXPathNSResolver()
| virtual DOMXPathNSResolver::~DOMXPathNSResolver ( ) | virtual |
|---|
Destructor.
◆ addNamespaceBinding()
| virtual void DOMXPathNSResolver::addNamespaceBinding ( const XMLCh * prefix, const XMLCh * uri ) | pure virtual |
|---|
Non-standard extension.
Associate the given namespace prefix to the namespace URI.
Parameters
| prefix | of type XMLCh - The namespace prefix to bind. An empty or null string denotes the default namespace. |
|---|---|
| uri | of type XMLCh - The associated namespace URI. If this argument is null or an empty string then the existing binding for this prefix is removed. |
◆ lookupNamespaceURI()
| virtual const XMLCh * DOMXPathNSResolver::lookupNamespaceURI ( const XMLCh * prefix) const | pure virtual |
|---|
Look up the namespace URI associated to the given namespace prefix.
Parameters
| prefix | of type XMLCh - The prefix to look for. An empty or null string denotes the default namespace. |
|---|
Returns
the associated namespace URI or null if none is found.
◆ lookupPrefix()
| virtual const XMLCh * DOMXPathNSResolver::lookupPrefix ( const XMLCh * URI) const | pure virtual |
|---|
Non-standard extension.
XPath2 implementations require a reverse lookup in the static context. Look up the prefix associated with the namespace URI
Parameters
| URI | of type XMLCh - The namespace to look for. |
|---|
Returns
the associated prefix which can be an empty string if this is a default namespace or null if none is found.
◆ release()
| virtual void DOMXPathNSResolver::release ( ) | pure virtual |
|---|
Called to indicate that this object (and its associated children) is no longer in use and that the implementation may relinquish any resources associated with it and its associated children.
Access to a released object will lead to unexpected result.
