XPathGenerator Class

The XPathGenerator takes an XmlNode object, and an XmlNamespaceManager as follows:

<line>XmlDocument doc = new XmlDocument();</line> <line>doc.Load("test.xml");</line> <line>XmlNode node = doc.DocumentElement.FirstChild.LastChild;</line> <line> </line> <line>XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);</line> <line>XPathGenerator gen = new XPathGenerator();</line> <line>string xpath = gen.GetXPath(node, nsmgr);</line>

The resulting string can then be used in SelectNodes or SelectSingleNodes using the same XmlNamespaceManager and it will find the same node as follows:

Copy Code

<line>XmlNode found = doc.SelectSingleNode(xpath, nsmgr); </line> <line>Debug.Assert(found == node);</line>
