howto get namespace info from schema
Hello,
Please help me with something I got stuck:
I want to get some information out ouf a schema and dont know howto do the following:
How do I get the xmlns:po attribute (targetnamespace) out of the following schema
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:po="http://openuri.org/easypo"
targetNamespace="http://openuri.org/easypo"
elementFormDefault="qualified">
I figured out that I can retrieve some info with this:
targetname space = xsModel.getComponents(XSConstants.TYPE_DEFINITION).item(0).getNamespace();
NamespacesList = xsModel.getNamespaces()
but I cannot find how to get for example the "xmlns:po" attribute for qualified Element names.
I want to create an xml and use this for createElementNS()
Creating an XML works, but I need to put in the namespace info from the schema.
Is this the correct way to extract namespace info out of a schema?
Thank you
Hubert

Hi Michael,
Thanks for the hint, this did not cross my mind.
I'll do that.

Hi Hubert,
XSModel is a model of the schema components [1] defined by the XML schema
specification. The XML representation of the schema is not part of this
model. If you want access to the namespace declarations I suggest you
process the schema document with one of the general purpose XML APIs (e.g.
SAX or DOM) and extract the namespace declarations from there.
Thanks.
