Thanks for your help, it has finally started to validate correctly. There are still some minor problems though.
1) Content validation is performed after the call to the overriden 'characters' method. I assumed the validation would be before you are sent the content so that you don't have to check the validity twice (once using code and once using schema). My current workaround is to parse twice. Once with an empty parser which just validates and then the real parser which processes all data as well. This works for me as I the amount of data isn't large, but I want to have a real solution. 2) During validation the input data is reformatted for some reason, linefeeds are replaced with spaces for example. Is there any way to stop this behaviour? / Per 2008/2/26, Alberto Massari <[EMAIL PROTECTED]>: > > Per Bernhardsson wrote: > > I have finally managed to find the time to answer you. :) > > > > This doesn't work for me for a very simple reason; the EntityResolver is > > never called. > > > > To explain a bit better: > > > > I would like to validate the following XML stream: > > > > <?xml version="1.0" encoding="UTF-8"?> > > <root> > > <intelem>1</intelem> > > <stringelem>string</stringelem> > > </root> > > > > using the following schema: > > > > <?xml version="1.0" encoding="UTF-8"?> > > <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; > > elementFormDefault="qualified" attributeFormDefault="unqualified"> > > <xs:element name="root"> > > <xs:complexType> > > <xs:sequence> > > <xs:element name="intelem" type="xs:int"/> > > <xs:element name="stringelem" type="xs:string"/> > > </xs:sequence> > > </xs:complexType> > > </xs:element> > > </xs:schema> > > > > As you can see there is no reference in the XML to the XSD, neither do I > > want there to be a reference anywhere as the source of XML stream is > > completely untrusted. > > > > Is what I'm looking for even possible to do with Xerces? > > > > > Yes; preload the schema using loadGrammar(.., true) to have it cached, > set the "use cached grammars" flag, set validation to "always" and your > XML will be validated > > > Alberto > > > > / Per > > > > 2008/2/25, Alberto Massari <[EMAIL PROTECTED]>: > > > >> Per Bernhardsson wrote: > >> > >>> I'm trying to parse and validate an XML stream using an in memory copy > >>> > >> of a > >> > >>> schema.
