Class XMLPrettyPrintOutputStream

java.lang.Object
  java.io.OutputStream
      com.pelzer.util.XMLPrettyPrintOutputStream

All Implemented Interfaces:

Closeable, Flushable

public class XMLPrettyPrintOutputStream
extends OutputStream

As you pass in non-pretty xml, this will write out 'pretty' xml as best it can, but without validating the underlying XML in any way (as using the xerces code would require). This class may result in munged XML if whitespace was significant to it in some way. In general, this class reads an entire line of the incoming text, then parses it when a newline or stream close command comes in. If the line is empty (only whitespace) then the line is dropped. If the line starts with a '<' (after removing whitespace) then the system indents that line based on its perceived current depth.

getPrettyPrinted

public static String getPrettyPrinted(String xml)

Takes a given XML as a string and does a pretty print. Internally creates streams, so if you already have a stream, it'll be more efficient to use this class as it was designed. This is mostly used for testing.
