class REXML::Formatters::Default

Public Class Methods

new( ie_hack=false ) click to toggle source

Prints out the XML document with no formatting – except if id_hack is set.

ie_hack: If set to true, then inserts whitespace before the close of an empty tag, so that IE's bad XML parser doesn't choke.

 @ie_hack = ie_hack
