[xsd-users] reading and writing non root elements

[Greg Carter]

Hi Boris,

Thanks for the reply.  I am trying to use the code given to read in an 
XML doc but I am getting errors at the point where the string is read 
into a DOMDocument object ( the parser->parse(wrap) line in the parse 
function).   I get a bunch of "error: Unknown Element 'MyEleType" and 
"error: Attribute 'someAtt' is not declared for element 'MyEleType'"

Do I need to tell Xerces about the schema that defines MyEleType?

Thanks
Greg.
