API XML to JSON format and back to XML

I'm using postman to test the following, later it will be automated but that's not the issue.
I'm requesting data from an XML based API and need to use the same data to send to a different API in XML format.
I've already figured out that I need to convert the XML to a JSON format in order to save it in a var. Which works.
However, the issue that I have is that this process creates extra characters in my data, in the form of: [{"$":
When I then continue to convert it back to XML (using the full function below), it doesn't work and I end up with an XML code with all over it. Which isn't accepted in the last post to the XML Api.
I want to achieve to remove all occurences of and in the XML var. But I think that I will need to get rid of the in the first step. [{"$":
I've already found a function (.replace) which removes it, but only the first occurence
Function JSON2XML
function json2xml(o, tab) {
var toXml = function(v, name, ind) {
var xml = "";
if (v instanceof Array) {
for (var i=0, n=v.length; i<n; i++)
xml += ind + toXml(v[i], name, ind+"\t") + "\n";
}
else if (typeof(v) == "object") {
var hasChild = false;
xml += ind + "<" + name;
for (var m in v) {
if (m.charAt(0) == "#")
xml += " " + m.substr(1) + "=\"" + v[m].toString() + "\"";
else
hasChild = true;
}
xml += hasChild ? ">" : "/>";
if (hasChild) {
for (var m in v) {
if (m == "#text")
xml += v[m];
else if (m == "#cdata")
xml += "<![CDATA[" + v[m] + "]]>";
else if (m.charAt(0) != "#")
xml += toXml(v[m], m, ind+"\t");
}
xml += (xml.charAt(xml.length-1)=="\n"?ind:"") + "</" + name + ">";
}
}
else {
xml += ind + "<" + name + ">" + v.toString() + "</" + name + ">";
}
return xml;
}, xml="";
for (var m in o)
xml += toXml(o[m], m, "");
return tab ? xml.replace(/\t/g, tab) : xml.replace(/\t|\n/g, "");
}
// Get the JSON from environment and parse it
let targetJSON = JSON.parse(pm.environment.get('firstTarget'));
// Convert it to XML String
let xmlString = json2xml(targetJSON);
// You can check the console if your string is correct
console.log(xmlString);
// Store the XML string as a variable and use this variable in your request body
pm.environment.set('targetXML', xmlString);
let resp = xml2Json(pm.response.text()),
targetData = resp.eExact.Accounts;
console.log({ targetData });
pm.environment.set('firstTarget', JSON.stringify(targetData));
This is the code which creates the [{"$":

Insert "and" before the last element jquery

var swTitle = {};
var favorite = [];
$.each($("input[name='Title']:checked"), function() {
favorite.push($(this).val());
console.log($("input[name='Title']:checked"));
});
swTitle.domain = favorite;
var List = {};
for (var m = 0; m < favorite.length; m++) {
var swTitleObj = [];
$.each($('input[name="' + swTitle.domain[m] + '"]:checked'), function() {
console.log(swTitle.domain[m]);
swTitleObj.push($(this).attr("class"));
console.log(swTitleObj);
});
List[swTitle.domain[m]] = swTitleObj;
}
var swSkillData = " ";
$.each(List, function(key, value) {
console.log(key + ":" + value);
swSkillData += '<li>' + key + '&nbsp' + ':' + '&#160' + value + '</li>';
});
Output will be like:
Fruits:Apple,Banana,Orange,Grapes
I want my output be like:
Fruits:Apple,Banana,Orange & Grapes
I have an array of keys and values separated by commas. I want to insert "and" and remove the comma before the last checked element. Kindly help me out with this issue.

I think you can reduce your code, with an option of adding and before the last element like,
var inputs=$("input[name='Title']:checked"),
len=inputs.length,
swSkillData='',
counter=0;// to get the last one
$.each(inputs, function() {
sep=' , '; // add comma as separator
if(counter++==len-1){ // if last element then add and
sep =' and ';
}
swSkillData += '<li>' + this.value + // get value
'&nbsp' + ':' + '&#160' +
this.className + // get classname
sep + // adding separator here
'</li>';
});
Updated, with and example of changing , to &
$.each(List, function(key, value) {
console.log(key + ":" + value);
var pos = value.lastIndexOf(',');// get last comma index
value = value.substring(0,pos)+' & '+value.substring(pos+1);
swSkillData += '<li>' + key + '&nbsp' + ':' + '&#160' + value + '</li>';
});
Snippet
var value ='Apple,Banana,Orange,Grapes';var pos = value.lastIndexOf(',');// get last comma index
value = value.substring(0,pos)+' & '+value.substring(pos+1);
console.log(value);

Here is an easy and customizable form of doing it.
(SOLUTION IS GENERIC)
$(document).ready(function() {
var ara = ['Apple','Banana','Orange','Grapes'];
displayAra(ara);
function displayAra(x) {
var str = '';
for (var i = 0; i < x.length; i++) {
if (i + 1 == x.length) {
str = str.split('');
str.pop();
str = str.join('');
str += ' and ' + x[i];
console.log(str);
$('.displayAra').text(str);
break;
}
str += x[i] + ',';
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Fruits : <span class="displayAra"></span>

str = str.replace(/,(?=[^,]*$)/, 'and')
I solved my own issue. I replaced my last comma with "and" using the above regex. Thanks to Regex!!!

Modifying innerHTML in nested get() jQuery

I'm currently using the jQuery get method to read a table in another page which has a list with files to download and links to others similar webpages.
$.get(filename_page2, function(response, status){
var data = $("<div>" + response + "</div>");
var target_element = data.find(target_element_type_page2 + '#' + target_element_id_page2)[0];
var container = document.getElementById(element_change_content_page1);
if (typeof target_element !== "undefined"){
var rows = target_element.rows;
for (var i = 1, n = rows.length; i < n; i++) {
var table = rows[i].cells[1].getElementsByTagName("TABLE")[0];
var isFolder = table.getAttribute("CType") == "Folder";
var elem = table.rows[0].cells[0];
var text = elem.innerText || elem.textContent;
var link = elem.getElementsByTagName("A")[0].getAttribute("href");
if (!isFolder) {
container.innerHTML += "<li class=\"mainfolderfile\">" + "<a class=\"filelink\" href=\"" + link + "\">" + text + "</a></li>";
} else {
container.innerHTML += "<li class=\"folderlist\">" + "<a class=\"folderlink\" onclick=\"open_submenu(this)\" href=\"#\">" + text + "</a><ul></ul></li>";
var elem_page1 = container.getElementsByTagName("li");
var container_page1 = elem_page1[elem_page1.length - 1].getElementsByTagName("ul")[0];
create_subfolder(container_page1, link);
}
}
} else {
container.innerHTML += "<li class=\"mainfolderfile\">" + "<a class=\"filelink\" href=\"" + "#" + "\">" + "Error..." + "</a></li>";
}
}, page2_datatype);
This is working fine, and all the folders and files are being listed. But when I try to do the same thing with the folders (calling the create_subfolder function) and create sublists with their subfolders and files, I'm getting a weird behavior.
function create_subfolder(container2, link1) {
$.get(link1, function(response, status){
var data = $("<div>" + response + "</div>");
var target_element = data.find("table" + "#" + "onetidDoclibViewTbl0")[0];
if (typeof target_element !== "undefined"){
var rows = target_element.rows;
for (var i = 1, n = rows.length; i < n; i++) {
var table = rows[i].cells[1].getElementsByTagName("TABLE")[0];
var elem = table.rows[0].cells[0];
var text = elem.innerText || elem.textContent;
var link2 = elem.getElementsByTagName("A")[0].getAttribute("href");
//nothing is changed in the webpage. The modifications in the html don't appear
container2.innerHTML += "<li>" + text + "</li>";
}
}
alert(container2.innerHTML); // Print the html with all the modifications
}, "html");
}
The second get(), inside the create_subfolder() function are not changing anything in the webpage, so no sublist is created. But, when I call the alert() function at the end of the get() function, it prints the code with all the modifications it should have made in the html at the second get callback. I believe the problem is related with the asynchronous behavior of the get function but I don't know exactly why. Any guess?

Javascript reflection - generic toString

now when I put my own Object in alert function I see
[Object object]
that is pointless information. is there any way using reflection to get all fields and values of those fields?

JSON.stringify is often times builtin and can serialize most objects you pass to it.
That said, you should probably just use a debugger or console.log instead of alert-ing things.

Here is one of many. But better to use console.log() then alert
function objectToString(o){
var parse = function(_o){
var a = [], t;
for(var p in _o){
if(_o.hasOwnProperty(p)){
t = _o[p];
if(t && typeof t == "object"){
a[a.length]= p + ":{ " + arguments.callee(t).join(", ") + "}";
}
else {
if(typeof t == "string"){
a[a.length] = [ p+ ": \"" + t.toString() + "\"" ];
}
else{
a[a.length] = [ p+ ": " + t.toString()];
}
}
}
}
return a;
}
return "{" + parse(o).join(", ") + "}";
}

sure, maybe something like
function alertObject(0){
var str = "";
for(i in o)
str += i + " " + o[i] + "\n";
alert(str);
}
Edit :: Note this is just a silly little example.

parsing JSON efficiently

so I'm parsing through a JSON object like so
if(val.function1!==""){
$("#contentFunction").text(val.function1);
}
if(val.function2!==""){
$("#contentFunction").text(val.function1 + "; " + val.function2);
}
if(val.function3!==""){
$("#contentFunction").text(val.function1 + "; " + val.function2
+ "; " + val.function3);
}
I'm wondiering if there is a better way of checking if my json object property is empty instead of having tons of conditions... this gets really messy if for instance I have up to val.function10
Thanks for your help

var strs = [];
for (var i = 0; i < 10; i++) {
var value = val["function" + i];
value && strs.push(value);
}
$("#contentFunction").text(strs.join("; "));

Something like this?
var content = "";
for (var prop in val) {
if (!val.hasOwnProperty(prop)) continue;
if (val[prop] !== "") {
content += "; " + val[prop];
}
}
Or in node.js (or modern browsers):
var c = Object.keys(val).filter(function (k) {
return val[k] !== "";
}).map(function (k) {
return val[k];
}).join("; ");

A tool like underscorejs will help you enumerate functions and properties.
