getNamedAttributeNode
Searches all sub-nodes of this node for jsp:attribute standard actions with the given name.This should always be called and only be called for nodes that accept dynamic runtime attribute expressions.
- Parameters:
name- The name of the attribute- Returns:
- the NamedAttribute node of the matching named attribute, nor null if no such node is found.
-
getNamedAttributeNodes
Searches all subnodes of this node for jsp:attribute standard actions, and returns that set of nodes as a Node.Nodes object.- Returns:
- Possibly empty Node.Nodes object containing any jsp:attribute subnodes of this Node
