Hi,
I'm newish to XSD, and am having some trouble with converting DTD mixed
content element into mixed complex types that reference groups. Having
tracked through the archives I'm kind of getting an idea of the problem, but
I'm still stuck as to a solution.
Say I had a DTD fragment like so:
<!ENTITY % foo "a | b | c">
<!ELEMENT z (#PCDATA | %foo; | d)*>
and for argument's sake a, b, c are PCDATA only and d implements a defined
complex type.
The datatype of (PCDATA | %foo | d) reoccurs in other elements, as does %foo
alone, so I have designed the schema equivalent as follows:
<xsd:group name="foo">
<xsd:choice>
<xsd:element name="a" type="xsd:string"/>
<xsd:element name="b" type="xsd:string"/>
<xsd:element name="c" type="xsd:string"/>
</xsd:choice>
</xsd:group>
<xsd:complexType name="dType">
<!-- etc... -->
</xsd:complexType>
<xsd:complexType name="zType" mixed="true">
<xsd:choice minOccurs="0" maxOccurs="unbounded">
<xsd:group ref="foo"/>
<xsd:element name="d" type="dType"/>
</xsd:choice>
</xsd:complexType>
<xsd:element name="z" type="zType"/>
The problem occurs when I attempt to validate with this. If I have the data:
<z>Confusion now <a>hath</a><!-- or any of b, c , or d --> made its
masterpiece.</z>
Then all string data after the first occurrence of a child element is
rejected (by XMLSpy) with the message: Text not allowed inside element "
Defining all the elements directly within the zType complex type works fine,
but I would rather construct the model using group fragments.
Any advice on how I can reference group/choice fragments in a mixed content
complex type?
Thanks in advance,
Stuart
