javascript Node ATTRIBUTE_NODE, CDATA_SECTION_NODE, COMMENT_NODE, DOCUMENT_FRAGMENT_NODE, DOCUMENT_NODE, DOCUMENT_TYPE_NODE, ELEMENT_NODE, ENTITY_NODE

This set of constants belongs to the root Node object of the W3C DOM, and is therefore inherited by all document-level nodes and elements. Each property corresponds to an integer value associated with the nodeType property of every DOM node. You can use these properties as a more plain-language way to indicate the node type your script is looking for in comparisons or similar operations.
