Hello,
I am wondering if it is possible in JSTL ....
A usual use of JSLT XML tags goes as
(1) by <x:parse var="MyDOM" ...> tag, parse a XML document in String to
obtain DOM instance in the scoped attribute specified by attribute "var",
(2) by <x:out select="${MyDOM}//...."/>, pull the contents as String to
show view.
Consider a case where a org.w3c.dom.Document object has been created and
stored within a request scope attribute before the JSP is invoked.
In MVC architecture, this situation is likely to happen. Actually I want to
do this in Struts : a Structs Action class produces a DOM and store it in
the request scope, then forward to a JSP.
In this situation I want to skip calling <x:parse> and apply <x:out> to the
pre-built DOM instance.
The reason why I want to skip is simple: avoid unnecessary XML parsing for
better performance. If I have a DOM already, then why do I have to
serialize the DOM into a String to pass to <x:parse> tag!?
I have tried to find out if this is possible in various resources, but no
such article/documentation I could find.
I also tried such coding :
<c:set var="MyDOM" value="${prebuild_DOM}"/>
<x:out select="${MyDOM}//*"/>
then I was welcomed by a NullPointerException.
Any idea?
