Greetings,
I intend to create a schema where I could validate that an element would
have children elements but the name attribute should be unique, or more
than that, be a key!
I've tried to define it with the element key ("service") but my tests
failed. I mean, my parser (Xerces2) and oxygen (ide tool) let pass that
constraint in my schema.
My question is if I have my schema well defined for that purpose. I put
the schema and test xml sample that should fail because I have two
elements with the same name ('service1').
Any ideas?
thanks,
Pedro Salazar.
Test case:
======= SCHEMA =========
<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:med="http://med/" targetNamespace="http://med/">
<xs:element name="serviceList" type="med:serviceListType">
<xs:key name="service">
<xs:selector xpath="serviceImport/serviceExport"/>
<xs:field xpath="@name"/>
</xs:key>
</xs:element>
<xs:element name="serviceImport" type="med:serviceImportType"/>
<xs:element name="serviceExport" type="med:serviceExportType"/>
<xs:complexType name="serviceImportType">
<xs:attribute name="name" use="required" type="xs:string"/>
</xs:complexType>
<xs:complexType name="serviceExportType">
<xs:attribute name="name" use="required" type="xs:string"/>
</xs:complexType>
</xs:schema>
========= XML ==============
<?xml version="1.0" encoding="ISO-8859-1"?>
<serviceList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://med/ file:/home/psalazar/med.xsd"
xmlns="http://med/" name="test" version="1.0">
<serviceImport name="service1"/>
<serviceExport name="service1"/>
</serviceList>
