Getting XML tags

Question

Hi,
I need to extract the list of the tags of an XML or DTD document. Do you know how could I do it?
For example, if I have:
<person>
<name></name>
<surname></surname>
<address></address>
</person>
i should obtain something like:
person, name, surname.
Or better a tree:
person
|
| | |
name surname address
Can anyone help me?
Thanx a lot.

Add xmlparserv2.jar to Classpath.
//Parse an XML document with a DOMParser.
DOMParser parser=new DOMParser();
parser.parse(new FileInputStream(new File("c:/input/input.xml")));
//Get the document parsed.
XMLDocument document=parser.getDocument();
//Get a node list of elements in the document.
NodeList nodeList=document.ElementsByTagName();
//List the elements in the document.
for(int i=0; i<nodeList.getLength(); i++)
System.out.println("Element "+ ((Element)(nodeList.item(i))).getTagName());
