Examples of org.jdom.xpath.XPath.selectSingleNode()

org.jdom.xpath.XPath.selectSingleNode()
Evaluates the wrapped XPath expression and returns the first entry in the list of selected nodes (or atomics). @param context the node to use as context for evaluatingthe XPath expression. @return the first selected item, which may be of types: {@link Element}, {@link Attribute}, {@link Text}, {@link CDATA}, {@link Comment}, {@link ProcessingInstruction}, Boolean, Double, String, or null if no item was selected. @throws JDOMException if the evaluation of the XPathexpression on the specified context failed.
