A class to format an XML string into indented xml code

Question

I am looking for a class or a piece of code to format an XML string into indented xml code
for example: an XML string as follows
<servlet><servlet-name>Login</servlet-name>servlet-class>ucs.merch.client.system.LoginServlet</servlet-class></servlet><servlet-mapping><servlet-name>Login</servlet-name>
to format into :
<servlet>
<servlet-name>Login</servlet-name>
<servlet-class>ucs.merch.client.system.LoginServlet</servlet-class>

Xerces has a class called OutputFormat
If you have your XML document in memory, you can format it using the method setIndenting(true) on the OutputFormat class. The following is an example:
assuming xmlDoc is our document and fileName is the name of the file we wish to write to:
OutputFormat format = new OutputFormat(xmlDoc);
// setup output file name
PrintWriter printwriter = new PrintWriter(new FileWriter(fileName, false));
// construct an XMLSerializer for writing the document
XMLSerializer serializer = new XMLSerializer( printwriter, format );
// Ensure output is indented correctly...
format.setIndenting(true);
// set serializer as a DOM Serializer
serializer.asDOMSerializer();
// serialize the document
serializer.serialize(xmlDoc);
hope this helps!
