In a DOM implementation which supports the 286N/A * XPath 3.0 feature, as described above, the <code>XPathEvaluator</code> 286N/A * interface will be implemented on the same object which implements the 286N/A * <code>Document</code> interface permitting it to be obtained by the usual 286N/A * binding-specific method such as casting or by using the DOM Level 3 286N/A * getInterface method. In this case the implementation obtained from the 286N/A * Document supports the XPath DOM module and is compatible with the XPath 286N/A * <p>Evaluation of expressions with specialized extension functions or 286N/A * variables may not work in all implementations and is, therefore, not 286N/A * portable. <code>XPathEvaluator</code> implementations may be available 286N/A * from other sources that could provide specific support for specialized 286N/A * extension functions or variables as would be defined by other 286N/A * Creates a parsed XPath expression with resolved namespaces. This is 286N/A * useful when an expression will be reused in an application since it 286N/A * makes it possible to compile the expression string into a more 286N/A * efficient internal form and preresolve all namespace prefixes which 286N/A * occur within the expression. 286N/A * @param expression The XPath expression string to be parsed. 286N/A * @param resolver The <code>resolver</code> permits translation of 286N/A * prefixes within the XPath expression into appropriate namespace URIs 286N/A * . If this is specified as <code>null</code>, any namespace prefix 286N/A * within the expression will result in <code>DOMException</code> 286N/A * being thrown with the code <code>NAMESPACE_ERR</code>. 286N/A * @return The compiled form of the XPath expression. 286N/A * @exception XPathException 286N/A * INVALID_EXPRESSION_ERR: Raised if the expression is not legal 286N/A * according to the rules of the <code>XPathEvaluator</code>i 286N/A * @exception DOMException 286N/A * NAMESPACE_ERR: Raised if the expression contains namespace prefixes 286N/A * which cannot be resolved by the specified 286N/A * <code>XPathNSResolver</code>. 286N/A * Adapts any DOM node to resolve namespaces so that an XPath expression 286N/A * can be easily evaluated relative to the context of the node where it 286N/A * appeared within the document. This adapter works like the DOM Level 3 286N/A * method <code>lookupNamespaceURI</code> on nodes in resolving the 286N/A * namespaceURI from a given prefix using the current information 286N/A * available in the node's hierarchy at the time lookupNamespaceURI is 286N/A * called. also correctly resolving the implicit xml prefix. 286N/A * @param nodeResolver The node to be used as a context for namespace 286N/A * @return <code>XPathNSResolver</code> which resolves namespaces with 286N/A * respect to the definitions in scope for a specified node. 286N/A * Evaluates an XPath expression string and returns a result of the 286N/A * specified type if possible. 286N/A * @param expression The XPath expression string to be parsed and 286N/A * @param contextNode The <code>context</code> is context node for the 286N/A * evaluation of this XPath expression. If the XPathEvaluator was 286N/A * obtained by casting the <code>Document</code> then this must be 286N/A * owned by the same document and must be a <code>Document</code>, 286N/A * <code>Element</code>, <code>Attribute</code>, <code>Text</code>, 286N/A * <code>CDATASection</code>, <code>Comment</code>, 286N/A * <code>ProcessingInstruction</code>, or <code>XPathNamespace</code> 286N/A * node. If the context node is a <code>Text</code> or a 286N/A * <code>CDATASection</code>, then the context is interpreted as the 286N/A * whole logical text node as seen by XPath, unless the node is empty 286N/A * in which case it may not serve as the XPath context. 286N/A * @param resolver The <code>resolver</code> permits translation of 286N/A * prefixes within the XPath expression into appropriate namespace URIs 286N/A * . If this is specified as <code>null</code>, any namespace prefix 286N/A * within the expression will result in <code>DOMException</code> 286N/A * being thrown with the code <code>NAMESPACE_ERR</code>. 286N/A * @param type If a specific <code>type</code> is specified, then the 286N/A * result will be returned as the corresponding type.For XPath 1.0 286N/A * results, this must be one of the codes of the 286N/A * <code>XPathResult</code> interface. 286N/A * @param result The <code>result</code> specifies a specific result 286N/A * object which may be reused and returned by this method. If this is 286N/A * specified as <code>null</code>or the implementation does not reuse 286N/A * the specified result, a new result object will be constructed and 286N/A * returned.For XPath 1.0 results, this object will be of type 286N/A * <code>XPathResult</code>. 286N/A * @return The result of the evaluation of the XPath expression.For XPath 286N/A * 1.0 results, this object will be of type <code>XPathResult</code>. 286N/A * @exception XPathException 286N/A * INVALID_EXPRESSION_ERR: Raised if the expression is not legal 286N/A * according to the rules of the <code>XPathEvaluator</code>i 286N/A * <br>TYPE_ERR: Raised if the result cannot be converted to return the 286N/A * @exception DOMException 286N/A * NAMESPACE_ERR: Raised if the expression contains namespace prefixes 286N/A * which cannot be resolved by the specified 286N/A * <code>XPathNSResolver</code>. 286N/A * <br>WRONG_DOCUMENT_ERR: The Node is from a document that is not 286N/A * supported by this <code>XPathEvaluator</code>. 286N/A * <br>NOT_SUPPORTED_ERR: The Node is not a type permitted as an XPath 286N/A * context node or the request type is not permitted by this 286N/A * <code>XPathEvaluator</code>.
