RE: Prefix question

Justin,

I think I have asked my question in a wrong way.

My application is NOT dependent on ‘ga’ prefix.    The output xml of

 

<readGroupRequest xmlns="http://ga.afl.com/">

  <groupNumber>12345</groupNumber>

</readGroupRequest>

 

is namespace qualified with a no-prefix.  That is fine.  My schema shows that this namespace is qualified with the ‘ga’ prefix. 

 

I thought that the attribute xmlns:ga="http://ga.afl.com/" in the <xs:schema> tag reflects that.  Isn’t that true? 

 

My question is that when I call getName().getPrefix() for this QName why is ‘ga’ not shown?

 

Thanks,

Parsers are free to choose their own prefixes (or none at all). Why is

your application dependent on the prefix "ga"? The URI to which this

prefix points is what's important, not the prefix itself.

I have a schema like the following

 

<xs:schema

targetNamespace="http://ga.afl.com/"

xmlns:xs="http://www.w3.org/2001/XMLSchema"

elementFormDefault="qualified"

attributeFormDefault="unqualified"

xmlns:ga="http://ga.afl.com/"

xmlns:png="http://ga.afl.com/png/"

xmlns:pnr="http://ga.afl.com/pnr/"

xmlns:ct="http://es.afl.com/ct/">

 

      <xs:import namespace=http://es.aflc.com/ct/ schemaLocation="ct.xsd"/>

      <xs:import namespace="http://ga.afl.com/png/" schemaLocation="Png.xsd"/>

      <xs:import namespace="http://ga.afl.com/pnr/" schemaLocation="Pnr.xsd"/>

 

     

      <xs:element name="readGroupRequest" type="ga:GroupIdentifierType"/>

 

      <xs:complexType name="GroupIdentifierType">

            <xs:choice>

                  <xs:element name="pngId" type="xs:integer"/>

                  <xs:element name="batchId" type="png:BatchIDType"/>

                  <xs:element name="groupNumber" type="ct:GroupNumberType"/>

            </xs:choice>

      </xs:complexType>

</xs:schema>

 

After the schema is compiled I do the following

 

SchemaType type = ReadGroupRequestDocument.type;

SchemaProperty[] schemaProperties = type.getElementProperties();

for(int i=0; i < schemaProperties.length; i++)

{

      SchemaProperty schemaProperty = schemaProperties[i];

      QName qName = schemaProperty.getName();

                       

      System.out.println("NamespaceURI: " + qName.getNamespaceURI());

      System.out.println("LocalPart: " + qName.getLocalPart());

      System.out.println("Prefix: " + qName.getPrefix());

}

 

The output of that code is

NamespaceURI: http://ga.afl.com/

LocalPart: readGroupRequest

Prefix:

 

 

What I do not understand is why the prefix is not “ga”.  The schema has this information.

 

I need to get this information out of the schema because the xml I generate must have this prefix.  I will use XMLOptions setSaveSuggestedPrefixes() method but I do not want to hardcode a prefix in my source code.  How else can I get the prefix from the schema?

 

Thanks,
