   Re: [xml-dev] How do you use multiple Namespaces in a Schema

[ Lists Home | Date Index | Thread Index ]

Marco,

You can do this - below is an example from Roger Costello's excellent
XFront W3C Schema tutorial [1]. This XML document references 3 separate
schema files, and assigns a separate namespace prefix (nikon, olympus,
and pentax) to each target namespace identifier (one per referenced
schema).

<?xml version="1.0"?>
<c:camera xmlns:c="http://www.camera.org";
                 xmlns:nikon="http://www.nikon.com";
                 xmlns:olympus="http://www.olympus.com";
                 xmlns:pentax="http://www.pentax.com";
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
                 xsi:schemaLocation=
                         "http://www.camera.org
                          Camera.xsd
                          http://www.nikon.com
                          Nikon.xsd
                          http://www.olympus.com
                          Olympus.xsd
                          http://www.pentax.com
                          Pentax.xsd">
    <c:body>
        <nikon:description>Ergonomically designed casing for easy
handling</nikon:description>
    </c:body>
    <c:lens>
        <olympus:zoom>300mm</olympus:zoom>
        <olympus:f-stop>1.2</olympus:f-stop>
    </c:lens>
    <c:manual_adapter>
        <pentax:speed>1/10,000 sec to 100 sec</pentax:speed>
    </c:manual_adapter>
</c:camera>

Hope this helps,
