Hi,
My report design has an input report parameter named 'xmlFile' with data
type String.
I do not want to pass 'xmlFile' into a data set. Instead, I want to
parse the value of 'xmlFile' first, and then I want to pass the result
of the parsing (could be a value of a node for example) to a data set.
I was thinking about writing an EventHandler class on a report
parameter. In this case 'xmlFile'.
Question:
Which EventHandler interface do I have to implement and which event in
particular?
I would appreciate your help.
Many thanks in advance.
Regards,
John

John,
There is not an event handler for the parameters.
You could do this in the beforeOpen script of a scripted data set like this:
importPackage(Packages.javax.xml.parsers);
importPackage(Packages.java.io);
importPackage(Packages.org.w3c.dom);
var filename = "C:\\src\\ref.xml";
var factory = DocumentBuilderFactory.newInstance();
var builder = factory.newDocumentBuilder();
var document = builder.parse(new File(filename));
function getTagValue(tagName) {
var nlist = document.getElementsByTagName(tagName);
return nlist.item(0).getFirstChild().getNodeValue();
}
Then call getTagValue on what you need.
or use the ScriptedDataSetEventAdapter
