Hello,

I discovered JAXB to Parse XML files. It is a fine thing and I tested
the examples of jwsdp-1.6/jaxb. All went ok, I created a xsd, a
build.xml which then created the nessecary Java Files.

Afterwards I created a simple xml file.

This is the xsd:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
          xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
          jxb:version="1.0">

 <xs:element name="AERORDROME">
   <xs:complexType>
     <xs:sequence>
       <xs:element name="RWY_ALOC_KEY" type="xs:int"/>
       <xs:element name="RWY_ID" type="xs:int"/>
       <xs:element name="RWY_LAST_UPDATE" type="xs:string"/>
       <xs:element name="RWY_OPERATOR" type="xs:string"/>
       <xs:element name="RWY_ILS_CAT" type="xs:string"/>
       <xs:element name="RWY_LOC_IDENT" type="xs:string"/>
       <xs:element name="RWY_LOC_TYPE" type="xs:string"/>
       <xs:element name="RWY_LOC_FREQ" type="xs:int"/>
       <xs:element name="RWY_LOC_DME_CHAN" type="xs:string"/>
     </xs:sequence>

   </xs:complexType>
 </xs:element>

</xs:schema>

this is an xml file:

<AERORDROME >
  <RWY_ALOC_KEY>1</RWY_ALOC_KEY>
  <RWY_ID>2</RWY_ID>
  <RWY_LAST_UPDATE>RWY_LAST_UPDATE781-555-1212</RWY_LAST_UPDATE>
  <RWY_OPERATOR>RWY_OPERATOR781-555-1212</RWY_OPERATOR>
  <RWY_ILS_CAT>RWY_ILS_CAT781-555-1212</RWY_ILS_CAT>
  <RWY_LOC_IDENT>RWY_LOC_IDENT781-555-1212</RWY_LOC_IDENT>
  <RWY_LOC_TYPE>RWY_LOC_TYPE781-555-1212</RWY_LOC_TYPE>
  <RWY_LOC_FREQ>4711</RWY_LOC_FREQ>
  <RWY_LOC_DME_CHAN>RWY_LOC_DME_CHAN781-555-1212</RWY_LOC_DME_CHAN>
</AERORDROME>

Withinn a Java application I could read the Data of the xml file:
public static void main( String[] args ) {
       try {
           // create a JAXBContext capable of handling classes
generated into
           // the example package
           JAXBContext jc = JAXBContext.newInstance( "example" );

           // create an Unmarshaller
           Unmarshaller u = jc.createUnmarshaller();

           // unmarshal a FooBar instance document into a tree of Java
content
           // objects composed of classes from the example package.
           AERORDROME aerodrome =      (AERORDROME)u.unmarshal( new
FileInputStream( "fsi.xml" ) );
           int  RWY_ALOC_KEY =  aerodrome.getRWYALOCKEY();
           String RWY_LAST_UPDATE =  aerodrome.getRWYLASTUPDATE();
           String RWY_OPERATOR =  aerodrome.getRWYOPERATOR();
           String RWY_ILS_CAT =  aerodrome.getRWYILSCAT();
           String RWY_LOC_IDENT =  aerodrome.getRWYLOCIDENT();
           String RWY_LOC_TYPE =  aerodrome.getRWYLOCTYPE();
           int RWY_LOC_FREQ =  aerodrome.getRWYLOCFREQ();
           String RWY_LOC_DME_CHAN =  aerodrome.getRWYLOCDMECHAN();

           System.out.println("RWY_ALOC_KEY[" + RWY_ALOC_KEY + "]");
           System.out.println("RWY_LAST_UPDATE[" + RWY_LAST_UPDATE +
"]");
           System.out.println("RWY_OPERATOR[" + RWY_OPERATOR + "]");
           System.out.println("RWY_ILS_CAT[" + RWY_ILS_CAT + "]");
           System.out.println("RWY_LOC_IDENT[" + RWY_LOC_IDENT + "]");
           System.out.println("RWY_LOC_TYPE[" + RWY_LOC_TYPE + "]");
           System.out.println("RWY_LOC_FREQ[" + RWY_LOC_FREQ + "]");
           System.out.println("RWY_ALOC_KEY[" + RWY_ALOC_KEY + "]");
           System.out.println("RWY_LOC_DME_CHAN[" + RWY_LOC_DME_CHAN +
"]");
...
}

Now I would like to read from one big xml file with a structure like
<AERORDROMES >
<AERORDROME >
  <RWY_ALOC_KEY>1</RWY_ALOC_KEY>
  <RWY_ID>2</RWY_ID>
  <RWY_LAST_UPDATE>RWY_LAST_UPDATE781-555-1212</RWY_LAST_UPDATE>
  <RWY_OPERATOR>RWY_OPERATOR781-555-1212</RWY_OPERATOR>
  <RWY_ILS_CAT>RWY_ILS_CAT781-555-1212</RWY_ILS_CAT>
  <RWY_LOC_IDENT>RWY_LOC_IDENT781-555-1212</RWY_LOC_IDENT>
  <RWY_LOC_TYPE>RWY_LOC_TYPE781-555-1212</RWY_LOC_TYPE>
  <RWY_LOC_FREQ>4711</RWY_LOC_FREQ>
  <RWY_LOC_DME_CHAN>RWY_LOC_DME_CHAN781-555-1212</RWY_LOC_DME_CHAN>
</AERORDROME>
<AERORDROME >
  <RWY_ALOC_KEY>1</RWY_ALOC_KEY>
  <RWY_ID>3</RWY_ID>
  <RWY_LAST_UPDATE>RWY_LAST_UPDATE781-555-1212</RWY_LAST_UPDATE>
  <RWY_OPERATOR>RWY_OPERATOR781-555-1212</RWY_OPERATOR>
  <RWY_ILS_CAT>RWY_ILS_CAT781-555-1212</RWY_ILS_CAT>
  <RWY_LOC_IDENT>RWY_LOC_IDENT781-555-1212</RWY_LOC_IDENT>
  <RWY_LOC_TYPE>RWY_LOC_TYPE781-555-1212</RWY_LOC_TYPE>
  <RWY_LOC_FREQ>4711</RWY_LOC_FREQ>
  <RWY_LOC_DME_CHAN>RWY_LOC_DME_CHAN781-555-1212</RWY_LOC_DME_CHAN>
</AERORDROME>
....
<AERORDROMES >

How can I realize this, or better how can I parse it?

Thanks for help.

Yours, Pitthekid.
