Answer 1

Another option is to parse the XML, and use the OutputKeys.INDENT option of the Transformer class to output the XML formatted.

The following example

Source source = new StreamSource(new StringReader(s));

TransformerFactory transformerFactory = TransformerFactory.newInstance();
transformerFactory.setAttribute("indent-number", 4);

Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");

StreamResult result = new StreamResult(new StringWriter());
transformer.transform(source, result);

String xmlOutput = result.getWriter().toString();
System.out.println(xmlOutput);

String xmlOutput = result.getWriter().toString();
System.out.println(xmlOutput);

produces the output below

<?xml version="1.0" encoding="UTF-8"?>
<Item>
    <productname>COOLER MASTER Hyper 212 EVO RR-212E-20PK-R2</productname>
    <Price>$33.99</Price>
    <ItemID>1000</ItemID>
</Item>
