For an XML document to be valid based on an XML schema, the XML document has to be validated against the XML schema.

Xdocument validate not validating

Now, all I had to do was validate the document against the XSD and, if it passed, get to decoding it via LINQ and we’re done and dusted in a few lines of code.

The XSD validation, by the way, looks like this; So, here you define the schema used in your XML file in the static readonly string called “SCHEMA”, then call Validate File(name of XML File, name of schema file).

The function either returns or throws Argument Null Exception or Xml Schema Validation Exception. Then I realised that, if you load any random XML file that If your XML file does not refer to the XSD then the validation passes, which is not what I intended.

by Deepak Vohra 09/15/2004 An XML schema defines the structure of the elements and attributes in an XML document.

Don’t get me wrong; it does everything I need it to do in describing multi-faceted data, but it’s a pretty steep learning curve.

At first, I used XPath and a lot of coded validation.

Then I finally invested time in learning XML Schemas (XSDs) and that helped because I could validate the entire document and, only when I knew it was valid, start pulling data out of it.

At around the same time, I stumbled upon LINQ to XML and this shortened the code substantially.

Extract the Xerces-J-bin.2.5.0(for Windows) or Xerces-J-bin.2.5.0gz (for Unix) files to the installation directory of your choice.

Add private class Validator extends Default Handler { public boolean validation Error = false; public SAXParse Exception sax Parse Exception = null; public void error(SAXParse Exception exception) throws SAXException { validation Error = true; sax Parse Exception = exception; } public void fatal Error(SAXParse Exception exception) throws SAXException { validation Error = true; sax Parse Exception=exception; } public void warning(SAXParse Exception exception) throws SAXException { } }Attribute( " Language", " Attribute( " Source", Schema Url);, using the JAXP parser.

For an XML document to be based on an XML schema, the XML document is required to be validated with the schema.
