Examples of org.jaxen.XPath.selectSingleNode()

org.jaxen.XPath.selectSingleNode()
Select only the first node that is selectable by this XPath expression. If multiple nodes match, only one node will be returned. NOTE: In most cases, the selected node will be the first selectable node in document-order, as defined by the XML Canonicalization specification. The exception occurs when using XPath expressions involving the union operator (denoted with the pipe '|' character).
@param The node, nodeset or Context object for evaluation. This value can be null @return The node-set of all items selectedby this XPath expression. @see #selectNodes
