How would I change the value of an attribute in an XML node using C#?

I have tried "findnode.Attributes["ID"].InnerText = newValue;"
and
"Attribute attri = (XmlAttribute)findnode.Attributes["ID"].Value;"

but Im stuck! When I try casting, it say that it cannot convert a string to
an XMLAttribute or when I try setting it to a new value it says "Object
reference not set to an instance of an object."

-------XML--------
<attr-inst id="20" state="known">
<val>100</val>
</attr-inst>

Thanks for any help,
Grant

> </attr-inst>


XmlAttribute attr = findnode.Attributes["id"] should give you the
attribute (remeber XML is case sensitive).
Then attr.Value="someText" should do it.

This may help;

findnode.Attributes.GetNamedItem["id"].Value = newValue;
