Use the node variable in foreach:
Use <C: Set Var = "nodevalue" Scope = "page" value = "$ {node}"/> to set the variable "Node" to pagecontext, and then use pagecontext. getattribute ("nodevalue.
<%
Node node = (node) pagecontext. getattribute ("nodevalue ");
Property titleprop = node. getproperty ("title ");
%>

Note: In the set tag, if the attribute scope = "request" is passed through the request. getattribute ("nodevalue"); get, if scope = "session" through request. getsession (). getattribute ("nodevalue.
