# Constructor. CData is data between <![CDATA[ ... ]]>
#
# _Examples_
# CData.new( source )
# CData.new( "Here is some CDATA" )
# CData.new( "Some unprocessed data", respect_whitespace_TF, parent_element )
def initialize( first, whitespace=true, parent=nil )
super( first, whitespace, parent, true, true, ILLEGAL )
end
# Make a copy of this object
#
# _Examples_
# c = CData.new( "Some text" )
# d = c.clone
# d.to_s # -> "Some text"
def clone
CData.new self
end
# Returns the content of this CData object
#
# _Examples_
# c = CData.new( "Some text" )
# c.to_s # -> "Some text"
def to_s
@string
end
# Generates XML output of this object
#
# output::
# Where to write the string. Defaults to $stdout
# indent::
# An integer. If -1, no indenting will be used; otherwise, the
# indentation will be this number of spaces, and children will be
# indented an additional amount. Defaults to -1.
# transitive::
# If transitive is true and indent is >= 0, then the output will be
# pretty-printed in such a way that the added whitespace does not affect
# the absolute *value* of the document -- that is, it leaves the value
# and number of Text nodes in the document unchanged.
# ie_hack::
# Internet Explorer is the worst piece of crap to have ever been
# written, with the possible exception of Windows itself. Since IE is
# unable to parse proper XML, we have to provide a hack to generate XML
# that IE's limited abilities can handle. This hack inserts a space
# before the /> on empty tags.
#
# _Examples_
# c = CData.new( " Some text " )
# c.write( $stdout ) #-> <![CDATA[ Some text ]]>
def write( output=$stdout, indent=-1, transitive=false, ie_hack=false )
#indent( output, indent ) unless transitive
output << START
output << @string
output << STOP
