[axis2] Parsing a WSDL file

[Andrej Taranenko]

Hi,
I am trying to parse a WSDL file, so I could print out the contents by 
its elements. The file is attached.
I am using the following code:
   XMLStreamReader parser = 
XMLInputFactory.newInstance().createXMLStreamReader(
                                                         new 
FileReader("ServisFirstTry1.wsdl"));
   StAXOMBuilder builder = new 
StAXOMBuilder(OMAbstractFactory.getOMFactory(), parser);
   OMElement root = builder.getDocumentElement();
  
   System.out.println("WSDL print ");
   
System.out.println("--------------------------------------------------");
   int i = 0;
   Iterator children = root.getChildren();
   while (children.hasNext()) {
       System.out.print(i+": "); i++;
       OMElement node = (OMElement) children.next();  // <--- exception 
here!
       System.out.println(node.getFirstElement().getText());
   }

but I get the following exception:
Exception in thread "main" java.lang.ClassCastException: 
org.apache.axis2.om.impl.llom.OMTextImpl
   at izpisWSDL.main(izpisWSDL.java:57)

if I use OMText instead of OMElement a different exception occurs.  Any 
help?

Thanks in advance,
Andrej
