Working with an API which return a xml not patterned

I am requesting an API sending to it words to be searched then retrieving the data from the API. Unfortunately the xml tree is not patterned, so I need to parse the xml file for each word with if statement.
like so:
if((JSON.stringify(result["entry_list"]["entry"][0]["sound"][0]["wav"][0])) !== undefined) {
...
...
}
I need to check if there are those elements in the xml, otherwise I will have an error saying: "TypeError: Cannot read property '0' of undefined".
The problems is that with that if I am not having success, so I would like to know what is the right way to lead with that situation?
Thanks in advance!

You can use object-get so that it will not throw error if the path is not there.
const objectGet = require('object-get')
const colour = objectGet(mammal, 'fur.appearance.colour')
const text = objectGet(el, 'children[2].children[1].children[1].textContent')
and just check like if (text) {}

Odd occurrence in using app.use(parseExpressRawBody())

Maybe this is simple, maybe this is a bug on Parse - would like to know if anyone has had the same problem and a possible solution.
What I'm trying to do:
I'm sending a JSON request from an app called FormEntry to my Parse app
The body comes in like this: json={"someLabel" : "someValue"}
I would like to take the entire body and create a Parse.Cloud.httpRequest over to Zapier to perform some functions.
Now, the problem seems to be this:
On random occasions (i.e. I have no idea why), the body is sent (as shown by the logs) where there is a trailing comma at the end of the last pair in the JSON object. e.g. like this json={"lastLabel" : "lastValue",}
The number of elements in 'normal' and 'incorrect' objects seem to be the same, so it's simply just another comma added. And I have no idea why.
My setup:
Using app.use(parseExpressRawBody()); only and not the standard app.use(express.bodyParser()); which doesn't provide access to the raw body.
Because parseExpressRawBody converts the body to a buffer I need to turn it back into a string to send it in the HTTP request in a meaningful way. Therefore I use: var body = req.body.toString();
When logging this var to the Parse console it looks to be format back from the buffer fine.
And that's about it. Nothing complex going on here but a real annoying bug that I just haven't found a sensible way of understanding. Would SUPER appreciate anyone who has seen this before or who could point me in a direction to focus on.

Just an update on this. Not a solution that answers why there is malformed JSON but a hack to get the right result.
The purpose of the HTTP request was to point over to Zapier so I wrote a Zapier script that would deal with the malformed JSON. Added here for anyone else who needs it.
"use strict";
var Zap = { newSubmission_catch_hook: function(bundle) {
var body = bundle.request.content;
var cleanTop = body.substring(5,body.length);
var cleanChar = cleanTop.length;
var condition = cleanTop.substring(cleanChar-2,cleanChar);
function testCase(condition,cleanTop) {
if (condition != ",}"){
console.log("Everything is fine, returning JSON");
return cleanTop;
}
else {
console.log("Nope! We have an error, cleaning end");
var cleanEnd = cleanTop.substr(0,cleanChar-2) + '}';
console.log("The object now ends with: " + cleanEnd.substr(-10));
return cleanEnd;
}
}
var newBody = JSON.parse(testCase(condition,cleanTop));
return newBody;
}
};

Script error: "Unable to get value of the property 'split': Object is null or undefined

I searched around, and couldn't find an answer to my question. I'm very new at coding, and at work, we have an application that current names that are logged in, and what they are doing.
Recently, they have changed from jquery 1.4.1 to jquery 1.8.3. Ever since then, I cannot get the results to process correctly, because of the following error;
"Unable to get value of the property 'split': Object is null or undefined"
I have the code setup to grab the results and split them;
function processAgents(xData, status) {
var avail = xData.responseText.split("|")[0];
var acw = xData.responseText.split("|")[1];
var total = xData.responseText.split("|")[2];
var breaks = xData.responseText.split("|")[3];
var pending = xData.responseText.split("|")[4];
The application is setup to open as an HTA file which opens up the PHP script.
Any help would be appreciated, please let me know if I left anything out!
Thanks!
EDIT 1
I did some more investigating, and it looks like I'm not getting data from my process request. This is how it is currently setup
function updateAgents() {
var ts1 = new Date().getTime();
$.ajax({
url: "http://SERVER/AgentSrc.php?x=" + ts1,
complete: processAgents
I'm not sure if this is processing correctly since they went to jquery 1.8.3.
EDIT 2
So after looking into it more, it doesn't appear that the script is getting the data from the server, even though I have access. If I make a local file and put the information in it, it will pull the information and split it, but if I point to the path of the file on the server, it won't get the information. But the strange thing is, if I run it using jquery 1.4.1, it pulls the data fine, but can't display it. But with 1.8.3, it doesn't allow me to pull it from the server.
thanks again!

This will give some clarity
xData.responseText.toString().split("|")[0];
(split is part of string not jQuery)

Here is a possible explanation: in earlier versions of jQuery, ajax calls returned an xmlHttpRequest (XHR) object. Recent versions return a promise (jqXHR) instead.

How to extract messages from the dashboard in Mirth?

How to extract messages from the dashboard in Mirth?
Basically using java script, how would I extract the information from dashboard in Mirth.
For example, I am after extracting the encoded data and ACK back from the destination.
One of the thing I tried was to run the following the postprocessor. But it’s only writing raw message not the encoded.
var log1file=D:\TEST\log1.txt;
var ReportBody=(messageObject.getEncodedData());
FileUtil.write(log1file, true, ReportBody);
Any suggestions much appreciated.
Thank you.

try this...
logger.info('start post script');
var status = responseMap.get('Destination Name').getStatus();
if ((status == "ERROR" || status == "FAILURE") )
{
logger.info("Status = "+status);
var errormsg = responseMap.get('Destination Name').getMessage();
logger.info(errormsg);
}
return;
getMessage() describe exception(error) description.

You wouldn't want to extract messages from the Dashboard. The dashboard is only showing the stored history from the database it keeps.
If you want to write the encoded data to a log file as the messages are processed, move that code from your post-processor over to a transformer javascript step in the source or in a destination (the encoded data changes from source to destination if you have transformer steps or if you change from HL7 to XML, etc.)
Is it actually creating the file? You don't have quotes around your file name and the backslashes should be forward slashes.

jsonp request not working in firefox

I am trying a straightforward remote json call with jquery. I am trying to use the reddit api. http://api.reddit.com. This returns a valid json object.
If I call a local file (which is what is returned from the website saved to my local disk) things work fine.
$(document).ready(function() {
$.getJSON("js/reddit.json", function (json) {
$.each(json.data.children, function () {
title = this.data.title;
url = this.data.url;
$("#redditbox").append("<div>" + title + "<div>");
});
});
});
If I then try to convert it to a remote call:
$(document).ready(function() {
$.getJSON("http://api.reddit.com", function (json) {
$.each(json.data.children, function () {
title = this.data.title;
url = this.data.url;
$("#redditbox").append("<div>" + title + "<div>");
});
});
});
it will work fine in Safari, but not Firefox. This is expect as Firefox doesnt do remote calls due to security or something. Fine.
In the jquery docs they say to do it like this (jsonp):
$(document).ready(function() {
$.getJSON("http://api.reddit.com?jsoncallback=?", function (json) {
$.each(json.data.children, function () {
title = this.data.title;
url = this.data.url;
$("#redditbox").append("<div>" + title + "<div>");
});
});
});
however it now stops working on both safari and firefox. The request is made but what is return from the server appears to be ignored.
Is this a problem with the code I am writing or with something the server is returning? How can I diagnose this problem?
EDIT Changed the address to the real one.

JSONP is something that needs to be supported on the server. I can't find the documentation, but it appears that, if Reddit supports JSONP, it's not with the jsoncallback query variable.
What JSONP does, is wrap the JSON text with a JavaScript Function call, this allows the JSON text to be processed by any function you've already defined in your code. This function does need to be available from the Global scope, however. It appears that the JQuery getJSON method generates a function name for you, and assigns it to the jsoncallback query string variable.

The URL you are pointing to (www.redit.com...) is not returning JSON! Not sure where the JSON syndication from reddit comes but you might want to start with the example from the docs:
$(document).ready(function() {
$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", function (data) {
$.each(data.items, function(i,item){
$("<img/>").attr("src", item.media.m).appendTo("#redditbox");
if ( i == 4 ) return false;
});
});
});
(apologies for formatting)
EDIT Now I re read your post, I see you intended to go to api.reddit.com unfortunately you haven't got the right parameter name for the json callback parameter. You might need to further consult the reddit documentation to see if they support JSONP and what the name of the callback param should be.

I'm not sure about reddit.com, but for sites that don't support the JSONP idiom you can still create a proxy technique (on the backend) that would return the reddit JSON, and then you would just make an ajax request to that that.
So if you called http://mydomain.com/proxy.php?url=http://api.reddit.com:
<?php
$url = $_GET["url"];
print_r(file_get_contents($url));
?>

http://api.reddit.com/ returns JSON, but doesn't appear to be JSONP-friendly. You can verify this, if you have GET, via
% GET http://api.reddit.com/?callback=foo
which dumps a stream of JSON without the JSONP wrapper.
http://code.reddit.com/browser/r2/r2/controllers/api.py (line 84) shows the code looking for 'callback' (not 'jsoncallback'). That may be a good starting point for digging through Reddit's code to see what the trick is.
