[xsd-users] schema with optional element in xml

[Bao Young]

Hello,

I am trying to set up a schema with optional elements in my xml file.
Example of my xml file:

  <Data>
      <record>
             <field1>abc</field>
             <field2>123</field>
             <subrecord>
                   <item1> false</item1>
                  <item2> def</item2>
             </subrecord>
      </record>
       <author> Jack </author>
        <datecreate>10052006</datecreate>
  </Data>

The xml file described above may have one or more element missing.
ie: <field1> </field1> and <autthor> </author> are optional elements.

How do I set up the schema and how do I access the field from the
application?

thanks,
Bao
