Validation

XML Schema is a W3C standard schema technology. It is a powerful schema language but can be complicated and hard to maintain.

A document can be validated against a XSD schema using the validateXSD accessor. The validateXSD accessor is provided by the ext_xml module.

Here is an example that validates the first Act of King Lear against an XML schema for the Act.

The result is a canonical boolean document with value true.

• King Lear XML Act 1
• act_schema.xsd

Here is another example but in this case the document has been deliberately corrupted. This shows the XSD error handling.
