Re: Validating XML documents against schemas
Hi Julie, If the target namespace of your schema document is " rrn:org.xcbl:schemas/xcbl/v3_0/xcbl30.xsd" then the documents you have are missing a namespace declaration for that namespace and thus aren't valid against the schema in their current state.

Re: Validating XML documents against schemas
Hi Michael
Thanks for your response.
I was pulled to another urgent project, so unfortunately had to leave this
unfinished.
However I am back now, and am keen to have another crack at getting this
working.
As stated previously my requirement is as follows :
> I am receiving XML documents from a number of different companies.
> The documents I receive can contain a variety of different
> schema/dtd declarations
> eg
>
>
> http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="rrn:

>

I am having some problems implementing the jaxp solution you suggested.
I have downloaded the latest xerces-2_9_0, and jaxp 1.3.
I am using the sample SourceValidator class, to do as you suggested.
However I am finding that the validator does not seem to be using the
schema alone to validate all my documents.
eg.
I have tried validating the following documents :
000420070323T09:55:10+10:00
...snipped
error: Parse error occurred -
D:\Eclipse\Workspaces\xerces-2_9_0\xerces-2_9_0\test\XCBL30.dtd (The
system cannot find the file specified)
000420070323T09:55:10+10:00
...snipped
[Error] NONE_301889302696_Order.txt:2:8: cvc-elt.1: Cannot find the
declaration of element 'Order'.
000420070323T09:55:10+10:00
[Error] SOX_301889302696_Order.txt:2:8: cvc-elt.1: Cannot find the
declaration of element 'Order'.
http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="rrn:org.xcbl:schemas/xcbl/v3_0/xcbl30.xsd Order.xsd">
000420070323T09:55:10+10:00
This document is the only one that actually performs the validation.
I am not sure if I am barking up the wrong tree with what I am trying to
do, or whether I just need to manipulate some features or properties of
the validator
ANy feedback you could give would be greatly appreciated.
Thanks
Julie

Re: Validating XML documents against schemas
Hi Julie,
Not sure what's wrong here (since you've left out some details), but you
may find it easier to get this working using the JAXP 1.3 Validation API.
You can compile your schema using the SchemaFactory [1] and then use the
Schema [2] object it returns for validation. Schema location hints
specified in your instance document will be ignored. There are samples
[3][4] included in the binary distribution which show how to do this.
Thanks.
