Examples of com.volantis.mcs.xml.xpath.XPath.selectSingleNode()

com.volantis.mcs.xml.xpath.XPath.selectSingleNode()
Evaluates the wrapped XPath expression and returns the first entry in the list of selected nodes. @param context the node to use as context for evaluating the XPathexpression. It must be an instance of one of the following ODOM/JDOM classes: ODOM/Element, ODOM/Attribute, ODOM/Text, ODOM/CDATA @return the first selected nodes, which is an instance of one of thefollowing ODOM/JDOM classes: ODOM/Element, ODOM/Attribute, ODOM/Text, ODOM/CDATA, Comment or ProcessingInstruction or null if no node was selected. @exception com.volantis.mcs.xml.xpath.XPathException if a Jaxen exception is raised.
