Generated Namespace Prexfix xmlns:Q1: How come? [message #22851] Mon, 19 May 2003 17:51 Go to next message

Hi there,
whenever I add an element reference to the method generating my schema (see
code below), the system automatically adds the namespace prefix
xmlns:Q1="..." to the schema it generates. How come? (I can get rid of it
when specifying a default namespace, but that's not want I want to...)
Thanks for help,

Dirk

(Example it an excerpt from library.xsd taken from the very good O'Reillly
book XMLSchema, author: E. van der Vlist)
public XSDSchema initializeSD3Schema() throws Exception {

XSDSchema xsdSchema = XSDFactory.eINSTANCE.createXSDSchema();

xsdSchema.setSchemaForSchemaQNamePrefix("xsd");

xsdSchema.setTargetNamespace("http://www.divos.de/sd3.xsd");

Map qNamePrefixToNamespaceMap =

xsdSchema.getQNamePrefixToNamespaceMap();

qNamePrefixToNamespaceMap.put(

xsdSchema.getSchemaForSchemaQNamePrefix(),

XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001);

XSDFactory xsdFactory = XSDSchemaBuildingTools.getXSDFactory();

String targetNamespace = xsdSchema.getTargetNamespace();

XSDElementDeclaration elementDecl = null;

elementDecl =

xsdSchema.resolveElementDeclaration(targetNamespace, "name");

XSDTypeDefinition typeDef =

xsdSchema.getSchemaForSchema().resolveSimpleTypeDefinition(

"string");

elementDecl.setTypeDefinition(typeDef);

xsdSchema.getContents().add(elementDecl);

elementDecl =

xsdSchema.resolveElementDeclaration(targetNamespace, "isbn");

typeDef =

xsdSchema.getSchemaForSchema().resolveSimpleTypeDefinition(

"string");

elementDecl.setTypeDefinition(typeDef);

xsdSchema.getContents().add(elementDecl);

xsdSchema.resolveElementDeclaration(targetNamespace, "author");

Dirk,

In order to reference anything in any namespace, an xmlns declaration is
required for the namespace. If there isn't one already specified, one is
created on demand. If you have a particular favorite prefix you want to use,
you should set it into the prefix map beforehand, e.g., this will create a null
prefix for the schema's target namespace:

qNameToPrefixMap.put(null, targetNamespace)
