Shema: problem with definition recursive data types
How can I describe the recursive date types?
I tried something like this:
<?xml version="1.0"?>
<schema>
<element name="aa" type="aaType"
minOccurs='0' maxOccurs='unbounded'/>
<complexType name="aaType">
<element name="aa" type="aaType" minOccurs="0" maxOccurs='unbounded'/>
</complexType>
</schema>
for the xml:
<aa xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'
xsi:noNamespaceSchemaLocation='re.xsd'
>
<aa>
<aa>
</aa>
</aa>
</aa>
I got the next errors:
[Error] re.xml:8:8: The content of element type "aa" must match "(aa)*".
[Error] re.xml:10:7: The content of element type "aa" must match "(aa)*".
Thanks,
Oleg Galis

Hi Eric,
What's about this answer ?
First,

> > xmlns='NS'
> > xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'

> > >

This file is absolutly correct .... In this case, "" is the
default prefix !!! I don't really what you want to say in your
answer.
Secondly, your solution is correct depending on
elementFormQualified (here, must be "unqualified")
in your schema !

This is really not so straightforward. a simple rule of thumb is to use
prefixes when you are using both schema and namespace.
The reason is that the parser conforms to the XML namespaces spec, which is
already a W3C recommendation. You sample xml file have a namespace bindings
between empty prefix "" and uri "NS", so every element tag "aa" will be
resolved to a qualifed name with uri "NS" and localpart "aa", but in your
content model of comlexType "aaType", the element "aa" is meant to be a
locally scope element without a unqualified name "aa", that's why the
validation complained about the mismatch between the actual children and the
content model.
You can change your xml file to :
<re:aa
xmlns:re='NS'
xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'
xsi:schemaLocation='NS re.xsd'
>
<aa>
<aa>
</aa>
</aa>
</re:aa>
the error should be gone.

Hi Eric,
I tried to bound schema to a targetNS, but it didn't solve the
problem. I got the same error.
xsd:
---------------------------------------------------------
<?xml version="1.0"?>
<schema
xmlns="http://www.w3.org/1999/XMLSchema"
xmlns:po="NS"
targetNamespace="NS"
>
<element name="aa" type="po:aaType"
minOccurs='0' maxOccurs='unbounded'/>
<complexType name="aaType">
<element name="aa" type="po:aaType" minOccurs="0" maxOccurs='unbounded'/>
</complexType>
</schema>
-------------------------------------------------------------
xml:
-------------------------------------------------------------
<aa
xmlns='NS'
xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'
xsi:schemaLocation='NS re.xsd'
>
<aa>
<aa>
</aa>
</aa>
</aa>
--------------------------------------------------------------
May be I have misunderstanding about term 'targetNS'? Any idea or working
samples would be helpful.
Thanks in advance

This is probably because you are using "noTargetNamespaceLocation", try it
with you Schema bound to a targetNS and see if you problem can be solved.
