Editing Xml

[Guest]

Hi,

I'm pretty new with XML, and I need to edit a XmlDocument in C#....

now here is an example on what I need.

I have this XMLDocument:

<?xml version="1.0"?>
<root>
<name>John Doe</name>
<conf class="7" uniqueid="1" password="0" />
<userlist>
<users id="1" userid="2" cardid="2"/>
</userlist>
</root>

Ok this is it.... you see the " <users id="1" userid="2" cardid="2"/>"...
that part is supposed to be added by me on the code... and I can't... I would
appreciate some help, hints and/or code snippet to see how can I do it.

Thanks in Advance

Well, first create an XmlDocument instance, then load the existing XML,
then find the element you wish to add something into (in this case the
userlist element), then create and add the new element (using
XmlDocument.CreateElement and XmlNode.AppendChild respectively). Set
the attributes you want on the element using XmlElement.SetAttribute.

I would suggest using XPath to find the userlist element - use
XmlNode.SelectSingleNode on the root node of the element, passing in
"/root/userlist" as the XPath expression.
