Trouble defining a list of elements in a xsd file when elements repeat
I am trying to write a xsd file to validate my xml. Here is a sample of the xml
<Record xmlns="http://example.com/FixedBinaryFile.xsd" Name="Clients">
<Padding Size="5">
<RecordEntry Name="Foo1" DataType ="Char"/>
<RecordEntry Name="Foo2" DataType="AnsiString" MaxSize="8"/>
<RecordEntry Name="Foo3" DataType="AnsiString" MaxSize="25"/>
<Padding Size="2"/>
<RecordEntry Name="Foo4" DataType="Byte"/>
<Padding Size="1"/>
<RecordEntry Name="Foo5" DataType="UInt16"/>
<RecordEn开发者_StackOverflow中文版try Name="Foo6" DataType="AnsiString" MaxSize="3"/>
<RecordEntry Name="Foo7" DataType="AnsiString" MaxSize ="3"/>
<Padding Size="22"/>
</Record>
and here is the xsd that defines it
<xs:element name="Record">
<xs:complexType>
<xs:sequence>
<xs:element name="RecordEntry" type="RecordEntry" minOccurs="1" maxOccurs="unbounded"/>
<xs:element name="Padding" type ="PaddingEntry" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="Name" type="xs:string" use ="required"/>
</xs:complexType>
</xs:element>
My problem is sequence
does not allow me to put padding entries where ever I want (right now I can have as many RecordEntry
entries as I want followed by as many Padding
entries as i want).
My inital thought was to use all
instead of sequence. However it won't let me use all
with maxOccurs
What do I need to do to define my list correctly?
EDIT: Freek had it right, here is what I had to change it to to make it work.
<xs:element name="Record">
<xs:complexType>
<xs:sequence minOccurs="1" maxOccurs="unbounded">
<xs:element name="Padding" type ="PaddingEntry" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="RecordEntry" type="RecordEntry" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="Name" type="xs:string" use ="required"/>
</xs:complexType>
</xs:element>
You can also set minOccurs and maxOccurs on the xs:sequence, setting that to appropriate values (probably minOccurs="0" maxOccurs="unbounded") should solve your problem.
