need help in XSD.

[S. Nitesh]

Hi,

I am a newbie in xsd.
I want to construct xsd for following xml format.

<a>
<b>some text<b/>
<c>some int<c/>
<d>some decimal<d/>
</a>

the main thing is that the xsd should allow <b>,<c> and <d> in any order with more than one occurrence of tag <d>.

thanks in advance.

Hi Nitesh,

There is the XSD schema:

   
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<!-- a element of type a_type -->
	<xsd:element name="a" type="a_type"/>	
		
	<xsd:complexType name="a_type">
		<!-- choose one of two -->
		<xsd:choice>
			<!-- b, d..., c, d... -->
			<xsd:sequence>
				<xsd:element name="b" type="xsd:string"/>
				<xsd:element name="d" type="xsd:decimal" minOccurs="0" maxOccurs="unbounded"/>
				<xsd:element name="c" type="xsd:integer"/>
				<xsd:element name="d" type="xsd:decimal" minOccurs="0" maxOccurs="unbounded"/>
			</xsd:sequence>
			<!-- c, d..., b, d... -->
			<xsd:sequence>
				<xsd:element name="c" type="xsd:integer"/>
				<xsd:element name="d" type="xsd:decimal" minOccurs="0" maxOccurs="unbounded"/>
				<xsd:element name="b" type="xsd:string"/>
				<xsd:element name="d" type="xsd:decimal" minOccurs="0" maxOccurs="unbounded"/>
			</xsd:sequence>
		</xsd:choice>
	</xsd:complexType>
</xsd:schema>

The solution has one constraint: The <d> element cannot be used as a first element in <a>.
I don't know if it could be solved better, this is the best solution I've found.

However, I hope it will help you.
