Using Namespaces with Xerces-J-2.4.0

18 Apr 2003 08:51:58 -0000

Hi All,

         I’m new to XML, so please excuse me if this sounds trival. I’m using Namespces and I have a default namespace plus another two. When I usse the Dom.Writer from the DOM samples from the Apache web site. I get the following errors. I’m not sure why I’m getting them, what do I have to do to my xml file to fix it?

 

[Error] Student1.xml:7:47: Attribute "xmlns:Sem" must be declared for element type "Student1".

[Error] Student1.xml:7:47: Attribute "xmlns:Per" must be declared for element type "Student1".

[Error] Student1.xml:7:47: Attribute "xmlns" must be declared for element type "Student1".

 

 

The command I’m using with DTD is:

 

java dom.Writer -v Student1.xml > Student2-dtd.xml

 

My XML file is listed below.

 

<?xml version='1.0' encoding='utf-8' ?>

 

<!DOCTYPE Student1 SYSTEM "Amend.dtd">

 

<Student1 xmlns:Sem='http://www.mastrocinque.com/Semester'

          xmlns:Per='http://www.mastrocinque.com/Permanent'

          xmlns='http://www.mastrocinque.com'>

         

      <PersonDetails InterStudent = 'No' ApprenticeTrainee = 'Yes'>

            <StudentNumber>8812209</StudentNumber>       

            <FamilyName>Mastrocinque</FamilyName>

            <GivenOtherNames>Harry</GivenOtherNames>

            <CourseTitle>Masters of Information Technology in Internet Devlopment</CourseTitle>

      </PersonDetails>

 

      <ChangeOfNameOrTitle AmendDateOfBirth = '07/06/2970' Date = '18/04/2003' Title = 'Mr'>

        <NewFamilyName>Sambucco</NewFamilyName>

        <NewGivenOtherNames>Jack</NewGivenOtherNames>       

      </ChangeOfNameOrTitle>

 

      <ChangeOfAddress>

        <Sem:SemesterAddress>                   

           <Sem:NumberOfStreet>45 McKean Street</Sem:NumberOfStreet>

           <Sem:SuburbOrTown>North Fitzroy</Sem:SuburbOrTown>

        </Sem:SemesterAddress>

       

        <Per:PermanentAddress>

           <Per:NumberOfStreet>86 Richardson Street</Per:NumberOfStreet>

           <Per:SuburbOrTown>North Carlton</Per:SuburbOrTown>

        </Per:PermanentAddress>

      </ChangeOfAddress>

 

</Student1>

 

My DTD file is
