#cdata_block(string) ⇒ Object

Adds the CDATA section content verbatim.

def cdata_block(string)
  last = stack.last
  last.add_node(CDataText.new(string)) if last
end

#characters(string) ⇒ Object

If this node is a successive character then add it as is. First child being a space-only text node will not be added because there is no previous characters, unless xml:space="preserve" is in effect.

def characters(string)
  last = stack.last
  if last and (preserve_whitespace? or last.children.last.is_a?(String) or string.strip.size > 0)
    last.add_node(string)
  end
end

#end_element(name) ⇒ Object

To keep backward behaviour compatibility delete last child if it is a space-only text node. CDATA content is literal and is never stripped, and under xml:space="preserve" whitespace-only text is kept too.

def end_element(name)
  preserve = preserve_whitespace?
  space_stack.pop
  if stack.size > 1
    last = stack.pop
    maybe_string = last.children.last
    if !preserve and maybe_string.is_a?(String) and !maybe_string.is_a?(CDataText) and maybe_string.strip.empty?
      last.children.pop
    end
    stack.last.add_node last
  end
end

#space_stack ⇒ Object

Tracks the xml:space value in effect for each open element so #preserve_whitespace? can honor XML 1.0 §2.10 inheritance.
