Problems using schema and namespaces
Hi all,
I have problems using namespaces and schema together in an application.
To be honest I don't no much about namespaces and schemas yet but have
to learn it. Ok, so what I am looking for is a simple xml-file like
personal-schema.xml and a corresponding xsd-file like personal.xsd but
which both uses also namespaces. Well, I know I could also start and
read the complete schema definition, but I would prefer to look at a
simple example first, so I get an idea what it's all about. Perhaps
somebody has something like that and would be so kind to post it here.
Thanks
stefan brauneis

Hi Alberto,
Thank you very much. That was exactly what I was looking for because all the
other examples I tried before had all some certain type or what so ever that
xercesc 1.5.1 doesn't support. And I can't write an example myself because if
you are not familiar with things you always wonder if it is your fault or the
librarys.
I would suggest to include such an example to xercesc because it shows both:
schema and namespaces. But of course I am just an ordinary user of the library
;-)

I think this is what you want:
[personal-schema-namespace.xml]
<my:personnel xmlns:my="urn:myns"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:myns personal-namespace.xsd">
<my:person id="Big.Boss" >
<my:name><my:family>Boss</my:family> <my:given>Big</my:given></my:name>
<my:email>chief@foo.com</my:email>
</my:person>
</my:personnel>
[personal-namespace.xsd]
<schema xmlns='http://www.w3.org/2001/XMLSchema' xmlns:ns="urn:myns"
targetNamespace="urn:myns">
<element name="personnel">
<complexType>
<sequence>
<element ref="ns:person" minOccurs='1' maxOccurs='unbounded'/>
</sequence>
</complexType>
</element>
<element name="person">
<complexType>
<sequence>
<element ref="ns:name"/>
<element ref="ns:email" minOccurs='0' maxOccurs='unbounded'/>
<element ref="ns:url" minOccurs='0' maxOccurs='unbounded'/>
<element ref="ns:link" minOccurs='0' maxOccurs='1'/>
</sequence>
<attribute name="id" type="ID" use='required'/>
<attribute name="note" type="string"/>
<attribute name="contr" default="false">
<simpleType>
<restriction base = "string">
<enumeration value="true"/>
<enumeration value="false"/>
</restriction>
</simpleType>
</attribute>
<attribute name="salary" type="integer"/>
</complexType>
</element>
<element name="name">
<complexType>
<sequence>
<element ref="ns:family"/>
<element ref="ns:given"/>
</sequence>
</complexType>
</element>
<element name="family" type='string'/>
<element name="given" type='string'/>
<element name="email" type='string'/>
<element name="url">
<complexType>
<attribute name="href" type="string" default="http://"/>
</complexType>
</element>
<element name="link">
<complexType>
<attribute name="manager" type="IDREF"/>
<attribute name="subordinates" type="IDREFS"/>
</complexType>
</element>
<notation name='gif' public='-//APP/Photoshop/4.0' system='photoshop.exe'/>
