There is more than one way to parse XML from string:

Example 1:

  String xml = "Your XML";
  DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
  DocumentBuilder db = dbf.newDocumentBuilder();
  Document doc = db.parse(new ByteArrayInputStream(xml.getBytes("UTF-8")));

Example 2:

Using a SAXParser which can read an inputsource:

 SAXParserFactory factory = SAXParserFactory.newInstance();
 SAXParser saxParser = factory.newSAXParser();
 DefaultHandler handler = new DefaultHandler() {
 saxParser.parse(new InputSource(new StringReader("Your XML")), handler);

See: SAXParser, InputSource

No, it doesn't work, cause this intruction only set the name of the element. – pseudo2188 Apr 11 '13 at 11:49
@Abu why should this be a comment? – CloudyMarble Apr 11 '13 at 12:16
@pseudo2188 it returns an org.jdom.Element from the string whats the output you expect? – CloudyMarble Apr 11 '13 at 12:16

I think, the OP wants to parse a whole XML document which is contained in the string. – vanje Apr 11 '13 at 13:59
Not the whole document, in my input, I have a String, but this String corresponds to an XML element, I have to compare it with other variables witch are really XML elements, so I have to convert the first one – pseudo2188 Apr 11 '13 at 15:11
@pseudo2188 Sorry i missunderstood the question, i updated my answer – CloudyMarble Apr 12 '13 at 04:25

Create a Document from your string. Look at JDOM FAQ: How do I construct a Document from a String?
Use method Document.getRootElement() to access the root element.

(You mentioned package org.jdom so I assume you work with JDOM 1.1.)

I usually do this, but for my exemple it not necessary, cause, I have to declare namespaces that I used, and construct a valid XML – pseudo2188 Apr 11 '13 at 15:20

I recommend you use the Simple XML Framework from http://simple.sourceforge.net/.With this framework you can serialize and deserialize your objects easily. I hope this information can be important for you.
