Transformer Source Code: Example & Question About a Repeating Item

[flugruger]

In another thread, @odoodo provided a way to export the source code of a transformer. This post follows on that with two items:

• An example of Mirth's core destination transformer code (Core Transformer v2.js.txt);
• A question about one part of the output.

Edit: Looked more closely. No longer a question. The first if else if is for the msg, the second is for the tmp.
Edit 2: Formatting, per @pacmano1.

In the attached file, the core of the transformer is this JS:

function doScript() {
msg = new XML(connectorMessage.getTransformedData());
if (msg.namespace('') != undefined) { default xml namespace = msg.namespace(''); } else { default xml namespace = ''; }
tmp = JSON.parse(template);
function filterRule1() {

	// FILTER JS WAS HERE, REMOVED
}
}function doFilter() { phase[0] = 'filter'; return ((filterRule1() == true)); }
function doTransform() { phase[0] = 'transformer'; logger = Packages.org.apache.log4j.Logger.getLogger(phase[0]);

	// TRANSFORM STEPS WERE HERE, JS REMOVED

if ('xml' === typeof msg) {
    if (msg.hasSimpleContent()) {
        msg = msg.toXMLString();
    }
} else if ('undefined' !== typeof msg && msg !== null) {
    var toStringResult = Object.prototype.toString.call(msg);
    if (toStringResult == '[object Object]' || toStringResult == '[object Array]') {
        msg = JSON.stringify(msg);
    }
}
if ('xml' === typeof tmp) {
    if (tmp.hasSimpleContent()) {
        tmp = tmp.toXMLString();
    }
} else if ('undefined' !== typeof tmp && tmp !== null) {
    var toStringResult = Object.prototype.toString.call(tmp);
    if (toStringResult == '[object Object]' || toStringResult == '[object Array]') {
        tmp = JSON.stringify(tmp);
    }
}
}
if (doFilter() == true) { doTransform(); return true; } else { return false; } 
}
doScript();

My question is about the if else if statements below where the transformer code was.
Those seem to be duplicates. Is this an artifact or is there some reason for doing this?

Thanks!

@flugruger use code highlighting please, you know better :).

As usual, @pacmano1 , I learned something from you. I had hit the code button in the editor and couldn't understand why it wasn't doing a code block. Now I know that I have to hit it three times. :)

[pacmano1]

if you add js after the 3 back ticks it colors the code also.

function doScript() {
    msg = new XML(connectorMessage.getTransformedData());
}

Raw viiew of that:

Thanks @pacmano1 !

They are not duplicates. The first if/else statement operates on the msg variable, and the second operates on the tmp variable.
