## Detailed Description

The `DOMXPathNSResolver` interface permit prefix strings in the expression to be properly bound to namespaceURI strings.

`DOMXPathEvaluator` can construct an implementation of `DOMXPathNSResolver` from a node, or the interface may be implemented by any application.

Since
  DOM Level 3

## Constructor & Destructor Documentation

## DOMXPathNSResolver()

DOMXPathNSResolver::DOMXPathNSResolver | ( |  | ) |

protected

## ~DOMXPathNSResolver()

virtual DOMXPathNSResolver::~DOMXPathNSResolver | ( |  | ) |

virtual

Destructor.

## Member Function Documentation

## 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.
