please help!

Hello,        I'm new in XML. And now I met a problem with xml schema.  I have designed a xml schema(try.xsd). And then I try to generate a new 
xml file(tryfirst.xml) which conform to that schema(try.xsd). But the 
result is : the content of the tryfirst.xml is much less than the content 
of the try.xsd. For example, in the schema I've defined 4 elements, but 
in the xml file only have 2 elements. I don't know what's happened.    
     Can anyone give me some solutions to this problem?        Thanks in advance!    
      Inge J.
