VB.NET code to validate xml against xsd file

[ragstta]

Hi all

Does anyone have any code which shows how i can use the system.xml objects to validate an xml file against its schema file (xsd) file. Need the code in vb.net 2.0. And need something wich will give me alot of error information for example what node is incorrect and data type and length errors.

Cheers

untested, but try this code:

Imports System
Imports System.Xml
Imports System.Xml.Schema
Imports System.Xml.XPath

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim myDocument As New XmlDocument
        myDocument.Load("C:\somefile.xml")
        myDocument.Schemas.Add("namespace here or empty string", "C:\someschema.xsd")
        Dim eventHandler As ValidationEventHandler = New ValidationEventHandler(AddressOf ValidationEventHandler)
        myDocument.Validate(eventHandler)
    End Sub

    Private Sub ValidationEventHandler(ByVal sender As Object, ByVal e As ValidationEventArgs)
        Select Case e.Severity
            Case XmlSeverityType.Error
                Debug.WriteLine("Error: {0}", e.Message)
            Case XmlSeverityType.Warning
                Debug.WriteLine("Warning {0}", e.Message)
        End Select
    End Sub

End Class
