Add subnodes to an existing node

[Grant]

Gday,

I am using the sample code at:
http://support.microsoft.com/default...b;en-us;317666 to modify an
existing XML document. The XML document looks like the following:

---------------------------
<parameters>
<Config-File>
<Value>c:\config.xml</Value>
</Last-Config-File>
<Modules />
</parameters>
---------------------------

What I would like to do is add subnodes to the <Modules /> node so the XML
file would end up looking something like:

---------------------------
<parameters>
<Config-File>
<Value>c:\config.xml</Value>
</Last-Config-File>

<Modules>
<Module1>
<somevalue>Text here</somevalue>
</Module1>
<Module2>
<somevalue>Text here</somevalue>
</Module2>
</Modules>

</parameters>
---------------------------

The problem with the sample code on the MSDN site is that the 'AppendChild'
function adds the node as a child node of the documents root node - I need
to add it to the modules node!

I really am stuck with this and any assistance would be greatly appreciated.

Thanks,
Grant

Grant,

Basically, you want to call the AppendChild method on the node that you
actually want to append the other values to. So, instead of calling it on
the DocumentElement, you should append it to the new element that you
appended to the document element (the modules element).

Hope this helps.

That was quick!
The problem is that the modules element already exists when I open the file,
and I dont know how to add new elements to an already exising one...

Try this

XmlNode rootNode = doc.DocumentElement;
XmlNode modulesNode= rootNode.SelectSingleNode ("Modules");
modulesNode.AppendChild(newElem);

I could have sworn I tried that! That works now.

Thank you for your help.
