XSD Complex Type

[Kanchana D S]

Hi,

I have a complex type which has to have its content in the xml instance
document as shown below :

<CONFIG_INFO>
<country resourceNumber="20004" fieldSecurity="5, 5">Great
Britain</label>
</CONFIG_INFO>

For this, I have defined the schema as below :

<xs:complexType name="AttributesType" mixed="true">
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="resourceNumber" type="xs:string"
default="20004"/>
<xs:attribute name="fieldSecurity" type="xs:string" default="5,
5"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>

<xs:element name="CONFIG_INFO">
<xs:complexType>
<xs:all>
<xs:element name="country" type="AttributesType"/>
</xs:all>
</xs:complexType>
</xs:element>

But I also have defined a named complex type for the text contained in the
element as shown below :

<xs:complexType name="COUNTRY_TYPE">
<xs:choice>
<xs:element name="CT_UK" fixed="Great Britain" type="xs:string"/>
<xs:element name="CT_GERMANY" fixed="Germany" type="xs:string"/>
</xs:choice>
</xs:complexType>

How do I asscoiate the text portion of the element "country" so that it
contains one of the defined values in "COUNTRY_TYPE"?

Thanks and regards,
Kanchana

You probably want to make COUNTRY_TYP Ean enumeration. Enumerations are
described at http://www.w3.org/TR/xmlschema-0/#ref10

I am aware of enumerations, but my doubt is not with respect to that point.
My doubt is - If I have to associate the "Text" portion of the element
"country" with the complex type "COUNTRY_TYPE", then how is it possible ?

What is "Text portion"? It's just content. Here is the schema using
enumerations just as Dare suggested:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:complexType name="AttributesType" mixed="true">
<xs:simpleContent>
<xs:extension base="COUNTRY_TYPE">
<xs:attribute name="resourceNumber" type="xs:string"
default="20004"/>
<xs:attribute name="fieldSecurity" type="xs:string" default="5,
5"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
<xs:element name="CONFIG_INFO">
<xs:complexType>
<xs:all>
<xs:element name="country" type="AttributesType"/>
</xs:all>
</xs:complexType>
</xs:element>
<xs:simpleType name="COUNTRY_TYPE">
<xs:restriction base="xs:string">
<xs:enumeration value="Great Britain"/>
<xs:enumeration value="Germany"/>
</xs:restriction>
</xs:simpleType>
</xs:schema>

It does not make sense for me to extend "AttributesType" from COUNTRY_TYPE
as they are 2 different global types. But I want the element "country" to
have attributes from "AttributesType" and its content from the COUNTRY_TYPE
global type, as I have shown below. How is this possible ?

<country resourceNumber="20004" fieldSecurity="5, 5">Great Britain</country>

Sounds like you are talking about multiple inheritance? XML Schema doesn't
support that.
But your AttributesType then looks quite artificial - if you want it to be
just collection of attribute definitions, why don't you use xs:attributeGroup?
Then country element definition can extend simple type COUNTRY_TYPE by
providing attribute definitions:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:attributeGroup name="myAttrs">
<xs:attribute name="resourceNumber" type="xs:string" default="20004"/>
<xs:attribute name="fieldSecurity" type="xs:string" default="5,
5"/>
</xs:attributeGroup>
<xs:element name="CONFIG_INFO">
<xs:complexType>
<xs:all>
<xs:element name="country">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="COUNTRY_TYPE">
<xs:attributeGroup ref="myAttrs"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
<xs:simpleType name="COUNTRY_TYPE">
<xs:restriction base="xs:string">
<xs:enumeration value="Great Britain"/>
<xs:enumeration value="Germany3"/>
</xs:restriction>
</xs:simpleType>
</xs:schema>

yeah your solution works for a specific case, but I am looking at a more
frequent usage of the 2 complex types wherein it might be too complicated to
use extensions like you have shown. See, the structure of my instance
document is as follows :

<PANEL_CLUSTER>
<CONFIG_INFO>
<label resourceNo="rr20003" fieldSecurity="5, 5">Cluster with 2
MagicPanels</label>
<country resourceNo="rr20004" fieldSecurity="5, 5">Great
Britain</country>
</CONFIG_INFO>
<APP_INFO>
<dialogFile>PanelClusterDlg.resx</dialogFile>
<deletable>0</deletable>
<default>1</default>
<subNodesPossible>1</subNodesPossible>
<helpIndex>%rr80202</helpIndex>
<icoName>PANEL_CLUSTER.ico</icoName>
<displayName>%rr80202</displayName>
<saveName>%rr80202</saveName>
<checkdate>null</checkdate>
</APP_INFO>
</PANEL_CLUSTER>

Now, I want to combine the attributes "resourceNo" and "fieldSecurity" under
one global complex type as all "CONFIG_INFO" elements in my instance
document will have to compulsorily contain these 2 attributes ( and there
will be multiple "CONFIG_INFO" elements in the instance document ). However
the content of these elements is variable and sometimes the content is one
of an enumeration (such as COUNTRY_TYPE), which is why I want to make this
enumeration as a global complex type. So the question is , I should make
each element under CONFIG_INFO contain the attributes "resourceNo" and
"fieldSecurity" and the content of some of these elements should be of an
enumerated type. How do I achieve both the goals ? And if multiple
inheritance is not supported what is the other alternative ? Or do I have to
follow the method you have suggested in the previous mail strictly ?

What's the point to define such a type instead of named attribute group?

Yeah I agree with you that it can be an attribute group, but still my
problem is not solved. Even with the previous solution you suggested I still
have some problem as I had mentioned in the earlier mail.

And to also add to my previous mail, the elements under "CONFIG_INFO" can
also be empty, so how then will the attributeGroup be referenced ?

Or if saying "can" you meant it may be empty or contain anything, that's just
xs:string:
<xs:element name="foo">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attributeGroup ref="myAttrs"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
