Schema building help

[johnsocs]

All -

I am very stuck on building a schema for the following xml message. I
feel I'm very close as the message validates if I remove the
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
attribute from the doSpellingSuggestion element. Any help/pointers for
describing the encodingStyle attribute in my schema would be great.

Any help on this would be great.

Thanks.

Why do you need to write your own schema for that, a schema already
exists, you could just import it e.g.

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
targetNamespace="urn:GoogleSearch"
xmlns:ns1="urn:GoogleSearch"
version="1.0">

<xsd:import namespace="http://schemas.xmlsoap.org/soap/envelope/"
schemaLocation="http://schemas.xmlsoap.org/soap/envelope/" />

<xsd:element name="doSpellingSuggestion"
type="ns1:doSpellingSuggestion"/>

<xsd:complexType name="doSpellingSuggestion">
<xsd:sequence>
<xsd:element name="key" type="xsd:string"/>
<xsd:element name="phrase" type="xsd:string"/>
</xsd:sequence>
<xsd:attribute ref="soapenv:encodingStyle" />
</xsd:complexType>

</xsd:schema>


If you really think you need to implement it yourself then look at the
schema at
<http://schemas.xmlsoap.org/soap/envelope/>
how that works. It has a global declaration for the attribute and its type.

Thanks for the reply

The message fails to to compile with using xmllint using the above
schema

I do not use xmllint and I am not familiar with its schema processor.
The message suggests that it does not find the referenced attribute
declaration so either an import is missing or you need to provide the
imported schemas on the command line too to have the processor find it.
