XSD

[Satish Gopalakrishnan]

I am new to Schema definitions...i am trying to define a parent tag which can have one or more children in any sequence...how do i do that using xsd
i.e i want the XSD to be able to accomodate
<parent>
<child1>sdf</child1>
<child2>ddd</child2>
</parent>
OR
<parent>
<child2>abcd</child2>
<child1>sdfadf</child1>
</parent>
i looked at the xsd samples and found the definiton for complex types (xsd:complexType) gives only all,sequence or choice as alternatives and none of them see to cover what i need....can somebody shed some light on this???

The <all> indicator specifies by default that the child elements can appear in any order and that each child element must occur once and only once:
I want one that can appear in any order multiple times
ex
<parent>
<child1>sdf</child1>
<child2>ddd</child2>
<child1>123123sdf</child1>
<child2>2314234ddd</child2>
</parent>

try this then

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="parent">
<xs:complexType>
<xs:choice maxOccurs="unbounded">
<xs:element name="child1"></xs:element>
<xs:element name="child2"></xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

this means i can have only one of child1 or child2 existing...i need both of them to co-exist in any order

Yes you can, try to validate this xml against the above schema

<parent>
<child1>Text</child1>
<child2>Text</child2>
<child1>Text</child1>
<child2>Text</child2>
<child1>Text</child1>
<child1>Text</child1>
<child2>Text</child2>
</parent>

but i don't know why you want to do this ?

[Satish Gopalakrishnan]

it works..sorry...
as to why i am doing this....
i am trying to hold contents of a document in an XML and have defined basic blocks like para,line etc which have to be used in this manner. I know this seems like a poor design but it gives me the maximum flexibility interms of changing the content easily.
