Example 1 with CanonicalFilter

use of nokogiri.internals.c14n.CanonicalFilter in project gocd by gocd.

the class XmlDocument method canonicalize.

     * that takes two parameters: the +obj+ and that node's +parent+.
     * The  +obj+ will be either a Nokogiri::XML::Node, or a Nokogiri::XML::Namespace
     * The block must return a non-nil, non-false value if the +obj+ passed in
     * should be included in the canonicalized document.
