[RESOLVED] Validate XML-text from (Rich)Textbox against XSD

Hi there,

I've been looking for a method to validate my xml(string) in a (rich)textbox against an .xsd. The best sample I've found is: http://www.vbforums.com/showthread.p...ainst-xsd-file, but it uses a "file". How to use it with a string in a (rich)textbox?

Thanks for the help in advance.

I'm getting close to solve this, but I'm getting an error in the following code:

Code:

---

dim ns as string = "http://schemas.microsoft.com/office/2009/07/customui"
dim xsdschema as string = mypathtoxsdschema

Dim x As New XmlDocument
x.LoadXml(myxml)
x.Schemas.Add(ns, xsdschema)

---

myxml:

Code:

---

customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">
  <ribbon startFromScratch="false">
      <tabs>
        <tab id="customTab" label="Custom Tab">
            <group id="customGroup" label="Custom Group">
              <button id="customButton" label="Custom Button" imageMso="HappyFace" size="large" onAction="Callback" />
            </group>
        </tab>
      </tabs>
  </ribbon>
</customUI>

---

ERROR: x.Schemas.Add(ns, xsdschema): The root element of a W3C XML Schema should be <schema> and its namespace should be 'http://www.w3.org/2001/XMLSchema'.

Think I got it. Need to test it properly...
