error generating ... Xml document (when calling web service)

[idletask]

Hello,

I have an XML file that is on my file system. I want to read the file
into memory and call a web service with it.

When I do, the VB complains:
"there was an error generating the XML document".

I see a lot of posts regarding serialization of classes. I am not that
familiar with serialization. Can I not just send the object to the web
service?

Right now I do this in the client:

Dim objXML as new XMLDocument
objXML.Load (MyFile)

....

then the web service call looks like this:

Dim WebService As New WebService.MyFunction
WebService.Submit(objXML) <-- here is where the problem occurs.

my Submit method accepts one arguement byVal as XMLDocument. I took
away my try.. catch block to see what type of error I would get, and in
my client program I have this in the file called reference.map:

Public Sub Submit(ByVal objXMLDocument As System.Xml.XmlNode)
Me.Invoke("Submit", New Object() {objXMLDocument})
End Sub

But in the web service itself - my Submit() Sub takes an argument
called XMLDocument.
I don't understand why these are different. I have tried updating the
web service, but the method signatures are different.

Is this a factor, or am I looking in the wrong direction?

Never mind- I fixed my own problem.

Since the xml document is a file, I just read it into a string. then I
passed it to my web service, converted the string to XML and now I can
process it.
