[xml] XML Schema Complex Type Sequence Incorrectly Ordered

[Wayne Milsted <wmilsted comcast net>]

Hi,

I'm using the libxml2 tree based API with a W3C Schema.  When writing elements to the document, libxml2 is not honoring the order of elements as defined in the schema.  Is this a bug or am I doing something incorrectly?

My XML document refers to the Schema as follows:

<?xml version="1.0" encoding="UTF-8"?>

<Domain xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Domain.xsd">

My schema has a complex type defined as follows:

 <xsd:complexType name="domain_type">

            <xsd:sequence>

            <xsd:element name="a" type="a_type" minOccurs="0" maxOccurs="unbounded"/>

            <xsd:element name="b" type="b_type" minOccurs="0" maxOccurs="unbounded"/>

            <xsd:element name="c" type="c_type" minOccurs="0" maxOccurs="unbounded"/>

            </xsd:sequence>

       

</xsd:complexType>

When the document is written out to a file, the elements do not follow the defined sequence a,b,c, producing an invalid document.

Thanks,

Waye
