pretty format a xml string

do you get most of the time xml not in a human readable format?

this snippet can help:
private String formatXml(String xml) {
        try {
            Transformer serializer = SAXTransformerFactory.newInstance().newTransformer();
            serializer.setOutputProperty(OutputKeys.INDENT, "yes");
            serializer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
            Source xmlSource = new SAXSource(new InputSource(new ByteArrayInputStream(xml.getBytes())));
            StreamResult res = new StreamResult(new ByteArrayOutputStream());
            serializer.transform(xmlSource, res);
            return new String(((ByteArrayOutputStream) res.getOutputStream()).toByteArray());
        } catch (Exception e) {
            return xml;
        }
    }
