schema problem 2003-03-05 - By Denis McCarthy
Hi there
I'm having a problem with some schema validation rules. I want to allow one
of two sequences to
be present in an xml document (I'd prefer not to have to use sequences, but
I don't think I can use <xsd:all within an xsd:choice tag). However, the
following xsd code rule only seems to allow the FIRST sequence to be
validated correctly - when I send an xml doc with the second sequence type I
get the following SAXParseTypeException:
org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content
starting with element
'ELEMENT_3' . The content must match
'((("":ELEMENT_1),("":ELEMENT_2))|((("":ELEMENT_1){0-1},("":ELEMENT_3)),("":
ELEMENT_4)))'.
As far as I can see, the content does match this. Can anyone see a problem
with this schema?
<xsd:choice>
<xsd:sequence>
<xsd:element name="ELEMENT_1" type="TYPE_1"/>
<xsd:element name="ELEMENT_2" type="TYPE_2"/>
</xsd:sequence>
<xsd:sequence>
<xsd:element name="ELEMENT_1" type="TYPE_1"
minOccurs="0"/>
<xsd:element name="ELEMENT_3" type="TYPE_3"/>
<xsd:element name="ELEMEMT_4" type="TYPE_4"/>
</xsd:sequence>
</xsd:choice>
Thanks
Denis
