XSD: and Labels

[fedro]

Dear Group,

on an existing project, i found this:

<docDefinition id="1">
<tagDefinition id="2" label="Bild" tagName="..

....

Now that look very like XSD and i like to do so, but i haven't found an
attribute in definitions fpr the "label" attribute here.

Any suggestions?

Thanks in advance,
Dominik

Hi Dominik,

That does not look like XSD.
You may wish to add mode details and eventual samples of what you are
looking for as I do not understand much from your post.

Best Regards,
George

i wanted to transform this XML-Structure to XSD.

OLD:
<docDefinition id="1">
<tagDefinition id="2" label="Bild" tagName="bild">
<attribute id="3" label="Ausrichtung" name="ausrichtung"
type="choice">
<value id="4" label="Links fließend">links</value>
<value id="5" label="Rechts fließend">rechts</value>
<value id="6" label="mittig">mitte</value>
</attribute>
</tagDefinition>
</docDefinition>


I started like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="bild" id="2" >
<xsd:complexType/>
</xsd:element>
</xsd:schema>

So i can "translate" the old tag ("tagDefinition") into xsd:element
with attribute "name". BUT this tag also got an attribute called
label="Bild".

Now i'm looking for the best way to tell the element, that it has got a
label. I tried with <xsd:annotation/>, but that look very dirty
and so i'm asking the group for best practices...

Hi Dominik,

There are tools that provided with a set of XML documents (one or more)
will be able to generate a schema for you. Then you can just adjust
that schema as you like. One such tool is TRANG that is also integrated
through a GUI in oXygen:
http://www.thaiopensource.com/relaxng/trang.html

For instance on your sample file it gives the following XML Schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="docDefinition">
<xs:complexType>
<xs:sequence>
<xs:element ref="tagDefinition"/>
</xs:sequence>
<xs:attribute name="id" use="required" type="xs:integer"/>
</xs:complexType>
</xs:element>
<xs:element name="tagDefinition">
<xs:complexType>
<xs:sequence>
<xs:element ref="attribute"/>
</xs:sequence>
<xs:attribute name="id" use="required" type="xs:integer"/>
<xs:attribute name="label" use="required" type="xs:NCName"/>
<xs:attribute name="tagName" use="required" type="xs:NCName"/>
</xs:complexType>
</xs:element>
<xs:element name="attribute">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" ref="value"/>
</xs:sequence>
<xs:attribute name="id" use="required" type="xs:integer"/>
<xs:attribute name="label" use="required" type="xs:NCName"/>
<xs:attribute name="name" use="required" type="xs:NCName"/>
<xs:attribute name="type" use="required" type="xs:NCName"/>
</xs:complexType>
</xs:element>
<xs:element name="value">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:NCName">
<xs:attribute name="id" use="required" type="xs:integer"/>
<xs:attribute name="label" use="required"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:schema>

Best Regards,

Thanks George, that's a nice tool. I used it for the XML-Document and
so i can skip that <docDefinition/> Part.

The problem with "labeling" (thats needed for the user-interface) i
solved as follows:

<xsd:element name="docDefinition">

<!--manual insert start-->
<xsd:annotation>
<xsd:appinfo>
<label name="DataStructure"/>
</xsd:appinfo>
</xsd:annotation>
<!--manual insert stop-->

<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="unbounded" ref="tagDefinition"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:integer" use="required"/>
</xsd:complexType>
</xsd:element>
