David, when you set the validation scheme to be "always", Xerces requires a schema for the document, and this document does not point to either a DTD or an XML Schema. You should add a
<!DOCTYPE xsd:schema SYSTEM "http://www.w3.org/2001/XMLSchema.dtd"; [ <!ENTITY % p 'xsd:'> <!ENTITY % s ':xsd'> ]> definition after the "<?xml version..." declaration Alberto At 11.00 29/05/2002 +0200, you wrote: >I am trying to parse the following schema (just like I would proceed to >parse any XML document) in order to get the values of some of its elements >and attributes.
