hello

I am writing a code that has 2 elements with the same name (example below). I need to keep both the elements, but each one to be with some of the attributes (the attributes will be divided to 2 groups).
the element data is called from 2 different parents. how can I make the different that each element will be called to his correct parent?
(I dont want to exchange the hirarchy)

<xs:element name="data">
- <xs:complexType>
  <xs:attribute name="class" use="required" type="xs:NCName" />
  <xs:attribute name="collection-id" use="required" type="xs:NCName" />
  <xs:attribute name="dbcolumn" type="xs:NCName" />
  <xs:attribute name="func" type="xs:NCName" />
  <xs:attribute name="last-summary" type="xs:NCName" />
  <xs:attribute name="mandatory" use="required" type="xs:NCName" />
  <xs:attribute name="type" use="required" type="xs:NCName" />
  </xs:complexType>
  </xs:element>


thanks

If the element declarations are local (<xs:element name="x" defined within an <xs:complexType>) then there is no problem having two elements with the same name but different content models. If you want to reuse attribute definitions or other parts of the content model you can do this by extending an abstract base type that contains the shared defintions, or you can use named attribute groups.

I will Rephrase the Q.
I have 2 elements, with different attributes. each element has a different father. my Q, is how exactly I can write the code that it will recieve both the elements with the same name (both the elements are not local.
here is what I mean in example if I wasn’t written the Q correctly:
xml file:
<etd version="">
   <entities>
      <entity eid="" tid="" plural-tid="" grouping-tid="" plural-grouping-tid="" length="">
         <data class="" type="" dbcolumn="" mandatory="" last-summary="" collection-id="" />
      </entity>
   </entities>
   <counters>
      <counter tid="">
         <data class="" type="" dbcolumn="" mandatory="" func="" collection-id="" />
      </counter>
   </counters>
</etd>

my Q again, is how do I write the code that It will be able to recognize the data attribute for each parent (if it is counter or entity.).
thank you very much.

What language are you writing the code in? Java, VB_Script, XSLT, XQuery?

I write the it in xsd schema. what I gave is part of the xml file that I am building the schema to.

OK, I thought it must be something different, because in that case my first answer covers it. The two elements entity and counter have different complex types, each of these complex types must include a local element declaration for data, and the two data elements define different sets of attributes.

Other possibilities are (a) redesign the document to avoid overloading the element name, or (b) recognize that you can't always validate everything in XML Schema - there will always be some constraints that have to be checked procedurally.

do you maybe have an example of how to write it, or a good website that has an examples of how to write it?

thanks

I don't know any good online tutorial sites for XML Schema. It's a complicated language and I wouldn't advise anyone to try and write schemas without first buying and studying a good book on the subject. Even though this is a Wrox site, I would be inclined first to recommend Eric van der Vlist (O'Reilly) or Priscilla Walmsley (prenticec-Hall).

I am trying to write for each element, to define type (for example:<xs:element name="display" type="entity-display" />)
I am encounter a problems:
1. if I will write another element with the same name but different type, it will shout that there are 2 elements with same name, no matter if it is other types.

I will appreciate if some one could give me an example how to write in a schema from this code example, how to make it valid that for each data element I will be able to give different attributes for each parent:


<etd version="">
   <entities>
      <entity eid="" tid="" plural-tid="" grouping-tid="" plural-grouping-tid="" length="">
         <data class="" type="" dbcolumn="" mandatory="" last-summary="" collection-id="" />
      </entity>
   </entities>
   <counters>
      <counter tid="">
         <data class="" type="" dbcolumn="" mandatory="" func="" collection-id="" />
      </counter>
   </counters>

waiting for an answer for whom ever can help me, I am kind of stuck.
thanks
