  • *
  • The attributes NamedNodeMaps are equal. This is: they are both null, * or they have the same length and for each node that exists in one map * there is a node that exists in the other map and is equal, although not * necessarily at the same index.
  • *
  • The childNodes NodeLists are equal. This is: they are both null, or * they have the same length and contain equal nodes at the same index. Note * that normalization can affect equality; to avoid this, nodes should be * normalized before being compared.
  • *

    * For two DocumentType nodes to be equal, the following conditions must * also be satisfied: *

    *

  • The following string attributes are equal: publicId, systemId, * internalSubset.
  • *
  • The entities NamedNodeMaps are equal.
  • *
  • The notations NamedNodeMaps are equal.
