Class AttrCompare

java.lang.Object
org.docx4j.org.apache.xml.security.c14n.helper.AttrCompare
All Implemented Interfaces:
java.io.Serializable, java.util.Comparator<org.w3c.dom.Attr>
public class AttrCompare
extends java.lang.Object
implements java.util.Comparator<org.w3c.dom.Attr>, java.io.Serializable
Compares two attributes based on the C14n specification.
  • Namespace nodes have a lesser document order position than attribute nodes.
  • An element's namespace nodes are sorted lexicographically by local name (the default namespace node, if one exists, has no local name and is therefore lexicographically least).
  • An element's attribute nodes are sorted lexicographically with namespace URI as the primary key and local name as the secondary key (an empty namespace URI is lexicographically least).
