Method Details

getInstance

public static UnmarshalXPathEngine getInstance()

Return the XPathEngine singleton.

selectSingleNode

public Object selectSingleNode(Node contextNode,
 XML_FIELD xmlField,
 XMLNamespaceResolver xmlNamespaceResolver,
 boolean checkForXsiNil)
                        throws XMLMarshalException

Execute the XPath statement relative to the context node.

Parameters:

contextNode - the node relative to which the XPath statement will be executed

xmlField - the field containing the XPath statement to be executed

xmlNamespaceResolver - used to resolve namespace prefixes to the corresponding namespace URI

Returns:

the first node located matching the XPath statement

Throws:

XMLMarshalException
