whats wrong with my XSD file

[taine]

I get the follwing error

> The element 'order' in namespace 'OrdersSchema' has invalid child
> element 'deliveryAddress'. List of possible elements expected:
> 'deliveryAddress' in namespace 'OrdersSchema'.


dunno if i understand it correct but isn't deliveryaddress a child of order ? so why is it complaining that its not expecting it ? or am i wrong in my think path

Hi,

This is a namespace problem.

In your XML, 'deliveryAddress' is in "no namespace" (or "null namespace", if you prefer) because you have not specified the default namespace for your XML (or individual elements).
Since your XML schema only accepts 'deliveryAddress' from the "OrdersSchema" namespace, the validator raises the error you mentioned.

A quick and dirty fix is to declare the default namespace on the root of the XML:

Code: Select all

<os:orders xmlns:os="OrdersSchema" xmlns="OrdersSchema">

However, if you're going to do this, you might as well remove the 'os' namespace prefix everywhere and just work with the default namespace. e.g.

Code: Select all

<orders xmlns="OrdersSchema">

    <order orderId="ord0001" type="standard">

...

The alternative is to use the declared namespace prefix, "os", everywhere. e.g.

Code: Select all

<os:orders xmlns:os="OrdersSchema">

    <os:order orderId="ord0001" type="standard"> 

        <os:deliveryAddress>

...
