How to Parse an XML string

Question

I need some help to parse an XML String instead of an XML file. The string can be like.
String myRecords =
"<data>"+
" <employee>"+
" <name>John</name>"+
" <Designation>Manager</Designation>"+
" </employee>"+
" <employee>"+
" <name>Sara</name>"+
" <Designation>Clerk</Designation>"+
" </employee>"+
"<data>"+

Answer 1

I tried it in a servlet, it and it worked. The entire code is long. But here it is most of it:
assuming that x is a string and has the xml of
<?xml version="1.0" ?>
- <company>
- <employee>
<firstname>Tom</firstname>
<lastname>Cat</lastname>
</employee>
- <employee>
<firstname>Paul</firstname>
<lastname>Enderson</lastname>
</employee>
- <employee>
<firstname>George</firstname>
<lastname>Jungle</lastname>
</employee>
</company>
=========================
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
InputSource inStream = new InputSource();
inStream.setCharacterStream(new StringReader(*x*));
Document doc = db.parse(inStream);
doc.getDocumentElement().normalize();
out.println("Root element " + doc.getDocumentElement().getNodeName() + "<BR>");
NodeList nodeLst = doc.getElementsByTagName("employee");
out.println("Information of all employees<BR>");
for (int s = 0; s < nodeLst.getLength(); s++) {
Node fstNode = nodeLst.item(s);
if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
Element fstElmnt = (Element) fstNode;
NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("firstname");
Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
NodeList fstNm = fstNmElmnt.getChildNodes();
out.println("First Name : " + ((Node) fstNm.item(0)).getNodeValue() + "<BR>");
NodeList lstNmElmntLst = fstElmnt.getElementsByTagName("lastname");
Element lstNmElmnt = (Element) lstNmElmntLst.item(0);
NodeList lstNm = lstNmElmnt.getChildNodes();
out.println("Last Name : " + ((Node) lstNm.item(0)).getNodeValue() + "<BR>");
} catch (Exception e) {
System.out.println(e);
out.close();
==============
The output is
Root element company
Information of all employees
First Name : Tom
Last Name : Cat
First Name : Paul
Last Name : Enderson
First Name : George
Last Name : Jungle
