Question

I got this answer to a question i asked yesterday about how to use a path to access an element-

Is it possible to do the opposite? means if i locate a specifiec element(level4 in the xml) with
GetElementsByTagName method is there a way to get the path for this elements and assign it
to a variable for later use?

<?xml version="1.0" encoding="utf-8" ?>
<level1> 
    <level2> 
        <level3>header3</level3> 
            <level4>header4</level4> 
        <level3>header31</level3> 
    </level2> 
    <level2> 
        <level3>nnn</level3> 
        <level3>nnnnn</level3> 
    </level2> 
</level1> 

Answer 1

Suppose you have extracted your node by

XmlNodeList nl = doc.GetElementsByTagName("level4");

then

        XmlNode node = nl[0]; 
        String sPath = node.Name;
        System.Xml.XmlNode np = node.ParentNode;
        while (np != null && np.NodeType != XmlNodeType.Document)
        {
            sPath = String.Format("{0}/{1}", np.Name, sPath);
            np = np.ParentNode;
        }
        sPath = "/" + sPath;
        Debug.WriteLine(sPath);

and you get “/level1/level2/level4” as the value of sPath

*Note: this in correct because in the input XML level3 is Sibling of level4 ( not Parent )
