Need advice about xpath resolving backwards

[janhm]

Hey, I had a problem with adding xml into a treeview few month ago. The
project got abandon, but im now working with it again.

Here is my problem:

I have an xml file containing:

<?xml version="1.0"?>
<kiosks>
<kiosk>
<kiosknavn>KIOS K001</kiosknavn>
<serienummer>00 1001001001</serienummer>
</kiosk>
<kiosk>
<kiosknavn>KIOS K002</kiosknavn>
<serienummer>00 2002002002</serienummer>
</kiosk>

and so on.

I then fill a treeview with all the <kiosknavn> in the xml. No problems
there...

Now I want to be able to search in the <kiosknavn> and have the content
displayed in another treeview.

If I search/click in treeview1 for KIOSK002 then I want the "KIOSK002" and
"0020020020 02" to be added into this second treeview.

I tried this :

treeView2.Nodes .Clear();
XmlDocument xDoc = new XmlDocument();
xDoc.Load("c://test.xml");
XmlNodeList nodes = xDoc.GetElement sByTagName("kio sknavn");
foreach(XmlNode node in nodes)
{
if (node.FirstChil d.FirstChild.Va lue == treeView1.Selec tedNode.Text)
{
treeView2.Nodes .Add(node.Outer Xml);
}
}

But it only results in :

Object reference not set to an instance of an object.

Any advice?

Thanks

looks like the only problem is that you're drilling too deep off of you
<kiosknavn> node. Should work if you just use the following code in your
loop...

foreach(XmlNode node in nodes){
if (node.FirstChil d.Value == treeView1.Selec tedNode.Text){
treeView2.Nodes .Add(node.Outer Xml);
}
}

Thanks.. that helped :)

It dosn't error anymore. Now it outputs <kiosknavn>kiok s002</kiosknavn> so
now i have something usable to work with.

thanks
