Unfortunately no :-(

 

I have an xml document like as:

<Document DOC_ID="1" version="1">

<doc_HEADER>

<header_field1>aaa</header_field1>

<header_field2>bbb</header_field2>

<header_field3>ccc</header_field3>

</doc_HEADER>

<doc_body>

<some_field1>sf1</some_field1>

<some_field2>sf2</some_field2>

<some_field3>sf3</some_field3>

<items>

<item>

<item_c>item_</item_c>

<item_q>1</item_q>

</item>

</items>

 

<field1></field1>
<field2></field2>
<field3></field3>
 
<field4></field4>
<field5></field5>
 

</doc_body>

</Document>

 

And doc_body can be in 3 variants

1. see upper (in xml document sample)

 

2.

<doc_body>

<some_field1>sf1</some_field1>

<some_field2>sf2</some_field2>

<some_field3>sf3</some_field3>

<items>

<item>

<item_c>item_</item_c>

<item_q>1</item_q>

</item>

</items>

 

<field1></field1>
<field2></field2>
<field3></field3>
 

</doc_body>

 

3.

<doc_body>

<some_field1>sf1</some_field1>

<some_field2>sf2</some_field2>

<some_field3>sf3</some_field3>

<items>

<item>

<item_c>item_</item_c>

<item_q>1</item_q>

</item>

</items>

 

<field4></field4>
<field5></field5>
 

</doc_body>

 

Variant 

<doc_body>

<!- some firlds -->

<field2></field2>
<field3></field3>
 
<field5></field5>

</doc_body>

Or something like is wrong.

 

And now XSD sees so

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

 <xsd:include schemaLocation="common_types.xsd"/>

 <xsd:element name="Document">

 <xsd:complexType>

 <xsd:all>

 <xsd:element name="doc_HEADER" type="type_doc_HEADER"/>

 <xsd:element name="ERRORS" type="type_ERRORS" minOccurs="0"/>

 <xsd:element name="doc_body" type="type_doc_body"/>

 </xsd:all>

 <xsd:attribute name="DOC_ID" type="xsd:int"/>

 <xsd:attribute name="version" type="xsd:int"/>

 </xsd:complexType>

 </xsd:element>

 <xsd:complexType name=" type_doc_body">

 <xsd:all>

 <xsd:element name=" some_field1" minOccurs="0"/>

 <xsd:element name=" some_field2" minOccurs="0"/>

 <xsd:element name=" some_field3" minOccurs="0"/>

<xsd:element name="field1"/>
<xsd:element name="field2"/>
<xsd:element name="field3"/>
<xsd:element name="field4"/>
<xsd:element name="field5"/>

 </xsd:all>

 </xsd:complexType>

</xsd:schema>

 

How I can change XSD for check all variants of doc_body ?
