[jdom-interest] newbie question

[Sylvain.Thevoz at swisscom.com]

Thank you all!!

My goal is to use JDOM to load an XML file, read it and retrieve content. This content will be used as a ini file in a XForm application.
So my examples was just to understand the JDOM concepts.

Maybe a bit more difficult:
I have a XML file like this
<document>
  <group name="Europe">
    <company name="LH">
      <fullname>Lufthansa</fullname>
    </company>
    <company name="SA">
      <fullname>Soviet Airlines</fullname>
    </company>
    <company name="AF">
      <fullname>Air France</fullname>
    </company>
  </group>
  <group name="US">
    <company name="AA">
      <fullname>American Airlines</fullname>
    </company>
  </group>
</document>


I want to retrieve content of this file and create a list of String that contain:
Europe
Europe->Lufthansa
Europe->Soviet Airlines
Europe->Air France
US
US->American Airlines


Anyone has experience?
Thank you very much
Sylvain

hi.

Your document does only contain one element at the "root" level
"<document>", so you have to get the children of that element and list
them...

To just paste the whole document to System.out an xml parser seems a bit
over kill :) But I guess that's not what your trying to do even though
that's your example.


try:


Element items = 
document.getRootElement().getChild("typeOfWorkstation").getChildren();

ListIterator itemIterator = items.listIterator();

while(itemIterator.hasNext()){

   System.out.println(
      ((Element)itemIterator.next()).getChildText("description")
   );
}


I didn't try this...so there might be some errors :))

Regards....
