Find position of XmlSchemaException in the XMLDocument

[adam0101]

I'm creating an application that allows a user to validate an XML document and update the document where the errors occur. First I load the XML document into a TreeView. Then I validate then document against a schema, which gives me a bunch of XmlSchemaException objects.

The problem is this - how do I find the error in the TreeView based on the schema exception? The exception tells me what line number the error occurs, but how do I translate that into an element in the XmlDocument, or even better - a node of the TreeView?

I found this article on MSDN that shows how to extend the XMLDocument object to capture line numbers by extending the XMLElement object. But when I populate the TreeView, I do so by doing a:

[tt][blue]For Each[/blue] node [blue]As[/blue] XmlNode [blue]In[/blue] document.ChildNodes[/tt]

I can't cast an XmlNode into my custom XmlElement, and there isn't a ChildElements collection as far as I can tell, so I'm kinda stuck.

Any ideas?

Thanks,

Adam

Nevermind, I used GotDotNet's version of the extended DOM and everything works perfectly.

FYI, I looked at how they did it and this was the line I was missing:

[blue]Dim[/blue] lineInfo [blue]As[/blue] IXmlLineInfo = [blue]CType[/blue](node, IXmlLineInfo)

I was trying to convert the node directly into the extended object instead of its interface.
