Using MSXML5 to Validate XML to Schema

[TimFromDallas]

I am using the following vb6 function to validate my xml against its schema file:


Function ValidateAsXmlFile(strFileName As String) As Boolean

Dim xmlDoc As MSXML2.DOMDocument50

Set xmlDoc = New MSXML2.DOMDocument50

xmlDoc.validateOnParse = True
xmlDoc.async = False
xmlDoc.Load (strFileName)

Select Case xmlDoc.parseError.errorCode
Case 0 ' Passed Validation
ValidateAsXmlFile = True
Case Else ' Failed Validation
ValidateAsXmlFile = False
MsgBox vbCrLf & "ERROR! Failed to validate " & _
strFileName & vbCrLf & xmlDoc.parseError.reason & vbCrLf & _
"Error code: " & xmlDoc.parseError.errorCode & vbCrLf & "Line: " & _
xmlDoc.parseError.Line & vbCrLf & "Character: " & _
xmlDoc.parseError.linepos & "", vbExclamation, "XML Failed to Validate Against Schema"
End Select

Set xmlDoc = Nothing

End Function


This works fine except that it only identifies the 1st error. You can't tell if there are follow-on errors. Once you correct this error and re-validate then you may find a 2nd error and so on. I would like to be able to see all errors at once. Any ideas?

Welcome to the forums.

Does the entire process stop when it encounters and error?

How do you call this Function?

It seems that it just finds any error and stops searching. My guess is it's designed like this in the MSXML. The method seems looks for any error and reports it and that's it. It doesn't seem to compile all the errors in a list. The xmlDoc.parseError.errorCode method within the MSXML5.DLL seems to exit after any one error found. There doesn't appear to be a way to set a starting or ending point to search for an error.

I call my VB function like this:

XMLValidated = ValidateAsXmlFile("C:\myXMLfile.xml")
