<para>You cannot edit the XML tree by using the <see cref="T:System.Xml.XPath.XPathNavigator" /> that is returned by this method. The <see cref="P:System.Xml.XPath.XPathNavigator.CanEdit" /> property returns false.</para>

<para>You cannot create an <see cref="T:System.Xml.XPath.XPathNavigator" /> for a <see cref="T:System.Xml.Linq.XDocumentType" /> node. Document types do not participate in the XPath data model.</para>

|
|
<para>Namespace declarations are reported from left to right. In contrast, for <see cref="T:System.Xml.XmlDocument" /> namespaces are reported from right to left. This is conformant behavior because namespace declarations are not ordered in the XPath data model.</para>

<para>You can use this method to perform an XSLT transformation. You can create an XML tree, create an <see cref="T:System.Xml.XPath.XPathNavigator" /> from the XML tree, create a new document, and create a <see cref="T:System.Xml.XmlWriter" /> that will write into the new document. Then, you can invoke the XSLT transformation, passing the <see cref="T:System.Xml.XPath.XPathNavigator" /> and <see cref="T:System.Xml.XmlWriter" /> to the transform. After the transformation successfully completes, the new XML tree is populated with the results of the transformation.</para>
|
||
|
|
<para>To perform an XSLT transformation, you can use either an <see cref="T:System.Xml.XmlReader" /> or an <see cref="T:System.Xml.XPath.XPathNavigator" />. The two approaches have different performance characteristics. Some transformations will execute faster when using an <see cref="T:System.Xml.XmlReader" />, and others will execute faster when using a <see cref="T:System.Xml.XPath.XPathNavigator" />. If performance is a concern, we recommend that you experiment with each approach to determine which will perform better in your circumstances.</para>
