Getting the namespace prefix

[Nick Betteridge]

I'm having difficulty in trying to get the namespace prefix.   When I get the SchemaGrammar and recurse down through the model, when I get to the simpleTypes (eg "xs:string") I can recover both the name and the namespace of the simpleType, but I can't work out how to recover the namespace prefix.   ie xsSimpleTypeDecl.getName()  will give me "string" xsSimpleTypeDecl.getNamespace() will give me http://www.w3.org/2001/XMLSchema   how do I get "xs" (defined in the example below)   I would be very grateful if someone would point me in the right direction.   Many trhanks Nick     <?xml version="1.0" encoding="UTF-8"?> <xs:schema     xmlns:xs="http://www.w3.org/2001/XMLSchema"     >     <xs:element name="responsemodel">         <xs:annotation>             <xs:documentation>filesystems response model</xs:documentation>         </xs:annotation>         <xs:complexType>             <xs:sequence>                 <xs:element name="response" type="xs:string"/>                 <xs:element name="exceptionThrown" type="xs:boolean"/>                 <xs:element name="exceptionMessage" minOccurs="0" type="xs:string"/>                 <xs:sequence>                     <xs:element name="children" minOccurs="0"                         maxOccurs="unbounded" type="xs:string"/>                 </xs:sequence>                 <xs:element name="booleanResponse" minOccurs="0" type="xs:boolean"/>                 <xs:element name="byteResponse" minOccurs="0" type="xs:base64Binary"/>                 <xs:element name="calendarResponse" minOccurs="0" type="xs:date"/>                 <xs:element name="longResponse" minOccurs="0" type="xs:int"/>             </xs:sequence>         </xs:complexType>     </xs:element> </xs:schema>
