Extracting the xml from string and parse it

Question

Hi all,
I have a webservice, and calling one of the methods, returns xml data but store this data in a string.
For example:
String str = keysstub.getUserLMLArray(UserID,hash, Provider, Filter.ALL,TimeStampString).getXmlResults();returns <id>123456</id><id>123457</id><id>123458</id><id>123459</id><id>123461</id>and stores it in str.
I have to take read this xml from the string and parse it accordingly to retreive the data from it.
Please suggest how i can parse this xml from the string. it will be of great help. Code snippets from anyone would be of great help
Thanks and Regards,
Shikha

      * Get DOM document from a string containing valid XML.
      * @param string String to read XML content from.
     * @param varargs Optional arguments: 1: Validating?, 2: NamespaceAware?
      * @return DOM document or null if failed.
     * @throws Exception if failed.
     static public Document toDocument(String string, boolean... varargs) throws Exception {
        Document result = null;
        if (string != null) {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            if (varargs != null && varargs.length > 0) {
                int count = varargs.length;
                if (count > 0) {
                    factory.setValidating(varargs[0]);  //needs error handler
                if (count > 1) {
                    factory.setNamespaceAware(varargs[1]);
            DocumentBuilder db = factory.newDocumentBuilder();
            result = db.parse(new InputSource(new StringReader(string)));
        }//else: input unavailable
        return result;
    }//toDocument()and don't forget that the string must be valid xml, so in your example the header is missing and the first element must embrace all subsequent elements, e.g.
<?xml version="1.0"?>
<ids>
<id>123456</id><id>123457</id><id>123458</id><id>123459</id><id>123461</id>
</ids>
