In particular the <code>rawIterator()</code> method with no arguments returns a Saxon <a class="bodylink" href="../../javadoc/net/sf/saxon/om/SequenceIterator.html"><code>SequenceIterator</code></a> which allows the application to process the results of any XPath expression, with no conversion: all values will be represented using a native Saxon class, for example a node will be represented as a <code>NodeInfo</code> and a QName as a <a class="bodylink" href="../../javadoc/net/sf/saxon/value/QNameValue.html"><code>QNameValue</code></a>. The <a class="bodylink" href="../../javadoc/net/sf/saxon/om/NodeInfo.html"><code>NodeInfo</code></a> interface is described in the next section.</p> <p>You can call methods directly on the <a class="bodylink" href="../../javadoc/net/sf/saxon/om/NodeInfo.html"><code>NodeInfo</code></a> object to get information about a node: for example <code>getDisplayName()</code> gets the name of the node in a form suitable for display, and <code>getStringValue()</code> gets the string value of the node, as defined in the XPath data model. You can also use the node as the context node for evaluation of subsequent expressions.</p> <table width="100%"> <tr> <td> <p align="right"><a class="nav" href="jaxp-xpath-extension-functions.xml">Next</a></p> </td> </tr> </table> </body> </html>
