Hi all,

I am also having difficulties validating an xml document.  I took the
xml and xsd from this post and implemented some of the suggestions
and have run into a few problems still.

I have added a default namespace so that my xsd file now looks like this:

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

<xsd:element name="shipOrder" type="order"/>
<xsd:complexType name="shipAddress">
<xsd:sequence>
<xsd:element   name="name"      type="xsd:string"/>
<xsd:element   name="street"    type="xsd:string"/>
<xsd:element   name="address"   type="xsd:string"/>
<xsd:element   name="country"   type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>

<xsd:complexType name="cdItem">
<xsd:sequence>
<xsd:element   name="title"     type="xsd:string"/>
<xsd:element   name="quantity"  type="xsd:positiveInteger"/>
<xsd:element   name="price"     type="xsd:decimal"/>
</xsd:sequence>
</xsd:complexType>

<xsd:complexType name="cdItems">
<xsd:sequence>
<xsd:element   name="item"      type="cdItem"/>
</xsd:sequence>
</xsd:complexType>

<xsd:complexType name="order">
<xsd:sequence>
<xsd:element   name="shipTo"    type="shipAddress"/>
<xsd:element   name="items"     type="cdItems"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>

Here are my two attempts at modifying my xml file:

Attempt 1:
<?xml version="1.0" encoding="UTF-8"?>
<foo:shipOrder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="AnotherTestSpace order_schema.xsd"
xmlns:foo="AnotherTestSpace"
>
<shipTo>
<name>Tove Svendson</name>
<street>Ragnhildvei 2</street>
<address>4000 Stavanger</address>
etc...

Attempt 2:
<?xml version="1.0" encoding="UTF-8"?>
<shipOrder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="AnotherTestSpace order_schema.xsd"
xmlns="AnotherTestSpace"
>
<shipTo>
<name>Tove Svendson</name>
<street>Ragnhildvei 2</street>
<address>4000 Stavanger</address>
etc...

In each case I get the following error:

[Error] simple.xml:5:2: General Schema Error: Grammar with uri 2:
AnotherTestSpace , can not found.

In addition I still get the other errors from before:

[Error] simple.xml:5:2: Element type "shipOrder" must be declared.
[Error] simple.xml:6:9: Element type "shipTo" must be declared.
etc...


I am using Xerces 1.3.0's SAXCount parser.
I verified that the xsd file is in fact named order_schema.xsd,
and that it exists in the same directory as my xml file.  I must be missing
something fundamental which I don't know about.
