Returns the node name represented by the token.
Description
This matches the DOM API value nodeName. Some values are static, such as #text for a text node, while others are dynamically generated from the token itself.
Dynamic names:
- Uppercase tag name for tag matches.
htmlfor DOCTYPE declarations.
Note that if the Tag Processor is not matched on a token then this function will return null, either because it hasn’t yet found a token or because it reached the end of the document without matching a token.
