This filter pretty-prints field-oriented XML without mixed content. all added indentation and newlines will be passed on down the filter chain (if any).

In general, all whitespace in an XML document is potentially significant, so a general-purpose XML writing tool like the XMLWriter class cannot add newlines or indentation.

There is, however, a large class of XML documents where information is strictly fielded: each element contains either character data or other elements, but not both.

This class can be used by itself or as part of a SAX event stream: it takes as input a series of SAX2 ContentHandler events and uses the information in those events to write an XML document.
