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

org.jdom.xpath.XPath.addNamespace()
Adds a namespace definition to the list of namespaces known of this XPath expression.
Note: In XPath, there is no such thing as a 'default namespace'. The empty prefix always resolves to the empty namespace URI.
@param namespace the namespace.

        xpath.addNamespace( "define", "jelly:define" );
        List taglibElements = xpath.selectNodes(doc);
        List taglibs = new LinkedList();
        for (Iterator iter = taglibElements.iterator(); iter.hasNext();)
        {
            Element element = (Element) iter.next();
