Need pretty-printing of XML once transforms happen

[sfloess]

Once we have transforms performed, we need to run the xml through a transform for pretty printing due to limitations in the Saxon HE.

Here are some reasonable links:

• http://www.java2s.com/Code/Java/XML/FormattinganXMLfileusingTransformer.htm
• http://myshittycode.com/2014/02/10/java-properly-indenting-xml-string/

Default Java transformer = com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

Will need to use the saxon transform to blindly transform and the aforementioned transformer to pretty print:

    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");

    StringWriter stringWriter = new StringWriter();
    StreamResult streamResult = new StreamResult(stringWriter);

    transformer.transform(new StringSource(xml), streamResult);

    System.out.println(stringWriter.toString());
