      <h1>Additional Saxon methods</h1>
      <p>Saxon's implementation of <code>XPathExpression</code> (namely <a class="bodylink"
            href="../../javadoc/net/sf/saxon/xpath/XPathExpressionImpl.html"><code>net.sf.saxon.xpath.XPathExpressionImpl</code></a>)
 provides additional methods for evaluating the XPath expression. 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>
