Am I using xs:anyType correctly?

[mphare]

I am trying to use a published Schema for a XRPC interface. The problem is I can't even validate the example XML they provide with their own schema. Either their schema has a flaw, or the schema validator used by Oxygen7.1 isn't working.

I lean toward the first so I did a simple example that contains the problem

Here's the XML file

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="urn:mph1 ../XSD/xsd-test-02.xsd" xmlns="urn:mph1">

    <first>

        <second>

            <NewFirst xmlns="urn:mph2">

                <NewSecond/>

            </NewFirst>

        </second>

    </first>

</root>

What I need is a schema that just address the 'mph1' namespace and ignores all others ('mph2' in this example)

First, this schema works. It does what I expect xs:anyType to do.. Ignore the NewFirst element and all that it contains.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"

  targetNamespace="urn:mph1" xmlns:mph1="urn:mph1">

  <xs:element name="root">

    <xs:complexType>

      <xs:sequence>

        <xs:element ref="mph1:first"/>

      </xs:sequence>

    </xs:complexType>

  </xs:element>

  <xs:element name="first">

    <xs:complexType>

      <xs:sequence>

        <xs:element ref="mph1:second"/>

      </xs:sequence>

    </xs:complexType>

  </xs:element>

  <xs:element name="second" type="xs:anyType"/>

</xs:schema>

Now, this is a modification to that working schema that reflects the published schema. It's supposed to do the same thing, but using the constructs as used by the published schema.

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"

  targetNamespace="urn:mph1" xmlns:mph1="urn:mph1">

  <xs:element name="root">

    <xs:complexType>

      <xs:sequence>

        <xs:element ref="mph1:first"/>

      </xs:sequence>

    </xs:complexType>

  </xs:element>

  <xs:element name="first">

    <xs:complexType>

      <xs:sequence>

        <xs:element ref="mph1:second"/>

      </xs:sequence>

    </xs:complexType>

  </xs:element>

  <xs:element name="second" type="mph1:secondType"/>

  <xs:complexType name="secondType">

    <xs:complexContent>

      <xs:restriction base="xs:anyType"/>

    </xs:complexContent>

  </xs:complexType>

</xs:schema>

The main difference is rather than an inline type, I use a complexType that resolved to xs:anyType. It should be the same as the first, right?

It's not. I get an error:

Code: Select all

SystemID: D:\mphare\Development\FW6500\XML\SchemaTest\xsd-test-01.xml

Location: 9:18

Description: cvc-complex-type.2.1: Element 'second' must have no character or element information item [children], because the type's content type is empty.

URL: http://www.w3.org/TR/xmlschema-1/#cvc-complex-type

Looks right to me.. the content of the second element should still resolve to xs:anyType.

Who's broken? The publiushed schema or the xsd validator?

Hi,

The content type for the secondType is empty, thus it cannot have any content, neither elements nor character data. To see how the content type is computed see
http://www.w3.org/TR/xmlschema-1/#key-efm

The default schema validator used by oXygen is Xerces J 2.8.0. You can however validate from oXygen also with other engines like XSV, LIBXML, MSXML 4.0, MSXML .NET and Saxon SA. For details about configuring them see the custom validation section from the user guide:
http://www.oxygenxml.com/doc/ug-oxygen/ ... validation
All of these validators above report the error on your example.

Best Regards,
George

Thanks George.

I've tried a few other validators and I also get the same error. That's why I was leaning toward the schema being incorrect.
