Using variables in JET [message #414700]

Hi All,

Can I use java/Jet variables in Jet templates.

Ex:

<c:setVariable select="somevalue" var="varaibaleName"/>

Here "somevalue" is not an XML XPATH expression. I want to assign
"somevalue" value to "varaibaleName" varibale name.

Just like java,

String varaibaleName = "somevalue";

How can I achieve in JET templates?

Thanks in advance.

Thiru,

It's best to ask about JET on the M2T newsgroup. I've added it to the
"to" list of the reply, so you don't need to repost.

How can I code on the java scriptlet?

<control:setVariable var="screenDefOfScreenList"
select=" $function//Event/ReferenceInformation/RelatedScreen/ScreenDe fOfScreenList "

<%
if(context.hasVariable("screenDefOfScreenList"))
{
NodeSet screenList =
(NodeSet)context.getVariable("screenDefOfScreenList");

// I don't know how to do below.....

EObjectInspector eObjectInspector = new EObjectInspector();
for (Iterator i = screenList.iterator(); i.hasNext();) {
Object object = i.next();
//eObject = (EObject)object;
Object[] screenDefAttributes = eObjectInspector.getChildren(object);
for (int j = 0; j < screenDefAttributes.length; j++){
//screenDefElement =
(ScreenDef)eObjectInspector.getParent(screenDefAttributes[j] );
%>
<%= eObjectInspector.nameOf(screenDefAttributes[j]) %>
<%
}
}
}
%>

Park:

The best thing to do would be to NOT try to process the NodeSet in Java
unless you really have to. Looking at your code fragment, you could do this
with JET tags:

<%-- iterate over screen lists --%>
<c:iterate
select=" $function//Event/ReferenceInformation/RelatedScreen/ScreenDe fOfScreenList "
var="listMember">
<%-- write some attribute of listMember to the output --%>
<c:get select="$listMember/@someAttribute name"/>

<%-- really tricky. See what attributes $listMember has --%>
<c:iterate select="$listMember/@*" var="listMemberAttr">
<c:get select="local-name($listMemberAttr")"/> = <c:get
select="$listMemberAttr"/>
</c:iterate>
</c:iterate>

Tell me more about what you want to do. I am happy to help.
