Hi Gareth,
thanks for your answer. I bound a prefix as you suggested and declared a namespace.
But in this case the parser generates also an error message. The parser does not accept
the namespace for the Schema B in connection with the include element. The parser suggests the import element.
But my Schema A und the Schema B have the same namespace. Consequently i think it is right to use the
include element.
 

How have you defined that they are in the same namespace? You don't 
appear to have declared an xsi:schemaLocation attribute.

Gareth

Do you have any further ideas?
Thanks in advance, Mirko

Hey,
 

thank you very much for your answer.
But i was not able to solve my problem.

   

You don't  seem to bound the prefix as I suggested. Is there any part of 
my answer that requires further explanation? Let me try using your 
schema fragment as an example:


 

Schema A:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <xsd:schema 
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
  <xsd:include schemaLocation="xhtml.xsd"/>

The Schema A uses one XHTML tag (<p>) (defined in Schema B) as a part 
of a ComplexType (please see below) definition.

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

   

Note here that the default namespace is the null namespace. You are 
trying to look up p in the null namespace, so it is not using p from 
schema B. You need to bind a prefix to the xhtml namespace. A rewritten 
version (I have not tested it, so forgive typos) might look like

<?xml version="1.0" encoding="UTF-8" standalone="no"?>  <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";  xmlns:xhtml="whatever the namespace is"> 
   <xsd:include schemaLocation="xhtml.xsd"/>
 
<xsd:element maxOccurs="unbounded" minOccurs="0" type="xhtml:p" name="p"/>

Schema xhtml (Schema B):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!--Version: 01.14.04-->
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
Errormessages of Xercesc 2-3-0:
"Type not Found in :p"
"Untyped element :p"

Can somebody help me?
Thanks in advance, Mirko

Hi,
     you are trying to reference p in the null namespace. You need to
bind a prefix to the xhtml namespace and then
reference it via that prefix.

Hi all,
i would like to parse a XML file validating against a Schema A. And 
this Schema A includes another Schema B (defines XHTML tags) . The 
code below shows the include mechanism of Schema B
in Schema A.

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
  <xsd:include schemaLocation="xhtml.xsd"/>
The Schema A uses one XHTML tag (<p>) as a part of a ComplexType 
(please see below) definition.

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


When i parse my XML file. The parser create following error messages:
"Type not Found in :p"
"Untyped element :p"
Can anybody help me?
Thanks in advance,
Mirko
