How insert,update,delete value of an XML element with Extendscript scriptui

I am learning extendscript for scripting adobe illustrator.It is very difficult for me to write xml related parsing.
My problem statement is given below:- "I have taken three text boxes namely name,city and country."name" is a unique key.when i click ok button the data must be saved in xml if name does not exist else update the previous name with out creating duplicate.All the names in xml file are displayed in list box.The date of particular name could be deleted by remove button.which will remove data in selected item of list box.
The code i tried to do is:-
var myWindow = new Window ("dialog", "Form");
var txt1 = myWindow.add ("edittext");//name unique
var txt2 = myWindow.add ("edittext");//city
var txt3 = myWindow.add ("edittext");//country
var btn=myWindow.add ("button", undefined, "OK");
btn.onClick = function () {
for (i=0;i<numberofnamesinxml;i++)//coding required
{
if(txt1.text!=xmlname[i]) // to verify name not there since it is like primary key
xmlFile.open("a");
xmlFile.write(root.toXMLString());
xmlFile.copy ('C:/data.xml');
xmlFile.close();
//myList refresh
}
}
var myList = myWindow.add ("listbox");
for (i=0;i<numberofnamesinxml;i++)//coding required
{
config='C:/data.xml';
config.open("r");
data= xmlname[i] //here i need to set data to
config.close();
myList.add ("item", data);
}
var btn1=myWindow.add ("button", undefined, "remove");
btn1.onClick = function () {
myList.remove (myList1.selection[i]);
//xml data having this list name must be removed
}
myWindow.show ();
Please kindly help me.

This should not be considered a full answer. I still post it because it might help finding one.
This is what I tried to write as an answer. The read/write part works but the checking of an element exists fails.
if the child is not an exact match, xml.contains(xml) will not return true.
var path = '~/Desktop/test.xml';
var xmlfile = File(path);
if (!xmlfile.exists) {
$.writeln('xml file does not exist. Creating new one');
xmlfile = new File(path);
xmlfile.open('w');
xmlfile.write('<Root></Root>');
xmlfile.close();
}
xmlfile.open('r');
xmlcontent = xmlfile.read();
xmlfile.close();
//$.writeln(xmlcontent);
var xml = new XML(xmlcontent);
// here the problems start
// the check is only working for known elements
var child = new XML('<name data="bob"></name>');
if (xml.contains(child)) {
child.#data = 'jim';
$.writeln('A child called "name" exists. Update');
xml.replace('name', child);
} else {
$.writeln('no child called "name" exists. Append');
child.#data = 'bob';
xml.appendChild(child);
}
xmlfile.open('w');
xmlfile.write(xml.toXMLString());
xmlfile.close();
My real answer is:
Use JSON instead.

Google Script: Format URL in Array.Push

I have a working script that upon form submit, specific rows move from one sheet to another. One of the fields I'm pushing is a url.
On the second sheet, the link is listed and it is hyperlinked, but it's really ugly and I really want to format it so that it shows "Edit" with a hyperlink. I've tried a number of ways, but my knowledge is limited so all I get are errors. I'm hoping someone can point me in the right direction.
Here is my code. I'm very new at this so the script is not at all sophisticated. Any help/suggestions would be appreciated!
function copyAdHoc(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = SpreadsheetApp.setActiveSheet(ss.getSheetByName("Form Responses 1"));
var data = sh.getRange(2, 1, sh.getLastRow() - 1, sh.getLastColumn()).getValues();
// Grab the Headers from master sheet
var headers = sh.getRange(1,1,1,sh.getLastColumn()).getValues();
var date = headers[0].indexOf('Effective Date');
var name = headers[0].indexOf('Employee Name');
var loc = headers[0].indexOf('Location');
var issue = headers[0].indexOf('Description/Question/Issue');
var add = headers[0].indexOf('Additional Information');
var change = headers[0].indexOf('Is this a Qualifying Life Event?');
var url = headers[0].indexOf('Form URL');
var category = headers[0].indexOf('Primary Category');
var status = headers[0].indexOf('Current Status');
var users = headers[0].indexOf('Users');
// Grab only the relevant columns
for(n = 0; n < data.length; ++n ) { // iterate in the array, row by row
if (data[n][change] !== "Yes" & data[n][category] !== "Employee Relations" & data[n][date] !== "") { // if condition is true copy the whole row to target
var arr = [];
arr.push(data[n][url]);
arr.push(data[n][users]);
arr.push(data[n][date]);
arr.push(data[n][loc]);
arr.push(data[n][name]);
arr.push(data[n][category]);
arr.push(data[n][issue] + ". " + data[n][add]);
arr.push(data[n][status]);
var sh2 = SpreadsheetApp.setActiveSheet(ss.getSheetByName("Ad Hoc")); //second sheet of your spreadsheet
sh2.getRange(sh2.getLastRow()+1,2,1,arr.length).setValues([arr]); // paste the selected values in the 2cond sheet in one batch write
}
}
}

It's a bit messy but the only way I know to achieve what you're trying to do would be to insert a column to the left of the hyperlink with the word Edit right justified and then remove the borders between the two.

From your description I am assuming you want the word "Edit" to be Hyperlinked. To do so, try this:
function getHyperlink(url)
{
return "=HYPERLINK(\""+url+"\","+"\"Edit\""+")";
}
function mainFunct()
{
//Do necessary steps
var tarLink = "https://www.google.com";
var tarRng = tarSheet.getRange(rowNum, colNum).setValue(getHyperlink(tarLink));
//perform other steps
}
EDIT:
Forgot to mention, since you're pushing your values to the array... you can do it in a similar way by either just storing the hyperlink in a variable or directly pushing it to the array like all the other values. Or if you're dealing with a hyperlink that has a static and dynamic part, For example: https://stackoverflow.com/questions/post_id, where post_id keeps changing but most of the URL is static, you can easily handle it by just passing the post_id to the getHyperlink function and getting the required Hyperlink in return. Hope this helps.

Get all items in NotesXSPDocument

In my Notes Database, I perform an audit when the document is saved. Pretty easy in LotusScript. I grab the original document (oDoc) from the server, then in the document I modified (mDoc), I do a Forall loop that gets the names of each item; forall item in mDoc.items. Grab the same item from oDoc, execute a function with the new item as an argument that will run down a case statement that will see if its a field we care about. if so, I update a set of list values in the document with "When", "Who", "What field", and the "New Value".
I'm doing this in a server side script. In trying this, I discovered a couple of interesting things;
currentDocument is the NotesXSPDocument that contains everything that was just changed.
currentDocument.getDocument() contains the pre-change values. It also returns a NotesDocument which has the "items" field that I can run through.
Thing is, I need something similar in the NotesXSPDocument. Is there a way in an iterative loop to grab the names and values of all items from there?
Here's the broken code. (Currently it's walking through the NotesDocument items, but those are the old values. I'd rather walk down the XSP document items)
function FInvoice_beginAudit() {
var original_doc:NotesDocument = currentDocument.getDocument();
var oItem:NotesItem;
var oItems:java.util.Vector = original_doc.getItems();
var iterator = oItems.iterator();
while (iterator.hasNext()) {
var oItem:NotesItem = iterator.next();
item = currentDocument.getItemValue(oItem.getName());
if (oItem == undefined) {
var MasterItem = ScreenAudit(doc,item,True)
if (MasterItem) { return true }
} else {
if (item.getValueString() != oItem.getValueString()) {
var MasterItem = ScreenAudit(doc,Item,True);
if (MasterItem) { return true }
}
}
}
}

You can get both versions of a document after submit - the original and the one with changed/new values:
original: var original_doc:NotesDocument = currentDocument.getDocument();
changed: var changed_doc:NotesDocument = currentDocument.getDocument(true);
This way you can compare the items for changes.
But, there is a pitfall: after assigning "changed_doc" to currentDocument.getDocument(true) the "original_doc" has the changed values too because both variables point to the same document. That's why we have to copy all items from currentDocument.getDocument() to a new temporary document first and only after get the changed values with currentDocument.getDocument(true). As an alternative you could read the original document from server like you do in LotusScript.
This is a code for detecting changed items as a starting point:
var original_doc:NotesDocument = database.createDocument();
currentDocument.getDocument().copyAllItems(original_doc, true);
var changed_doc:NotesDocument = currentDocument.getDocument(true);
var oItems:java.util.Vector = original_doc.getItems();
var iterator = oItems.iterator();
while (iterator.hasNext()) {
var oItem:NotesItem = iterator.next();
var itemName = oItem.getName();
var cItem:NotesItem = changed_doc.getFirstItem(itemName);
if (cItem.getText() !== oItem.getText()) {
print("changed: " + itemName);
}
oItem.recycle();
cItem.recycle();
}
original_doc.remove(true);
original_doc.recycle();

Page with multiple dropdown filters

I have a page which uses dropdowns to filter a listing. I have over 10 filters now and each of the change function, I am calling an AJAX request and passing corresponding variables to the PHP function. Like this :
$("#categories").change(function() {
uri = "myurl" ;
var status=$("#statusfilter").val();
var category=$("#categories").val();
var network=$("#networksfilter").val();
var prod_type = $("#prodtypefilter").val();
loadData(uri,category,status,network,prod_type);
});
and in loadData() I have the following code :
function loadData(uri,category,status,network,prod_type){
url + = category+"/"+status+"/"+network+"/"+prod_type;
$('#userdata').load(url);
}
Here I have given only 4 filters only, but it is actually 10 and may increase.Anyway this is working fine. But the problem is that as I increase the filters, I need to write this same for every dropdown change function. Is there any better approach to optimze the code and so I don't need to load a bunch of JS ?

Rename your filter elements' IDs to start with same word, for example "filter_". Then get all of them at once:
$('select[id^="filter_"]').change(function() {
var uri = "myurl";
var filters = new Array();
$('select[id^="filter_"]').map(function () {
filters[$(this).name()] = $(this).val(); // not tested, just an idea
});
loadData(uri,filters);
});
.map() iterates over its elements, invoking a function on each of them and recording the selected option value in the array.
You can use .each() if it's more intuitive from .map() for you:
$.each('select[id^="filter_"]', function() {
filters[$(this).name()] = $(this).val(); // not tested, just an idea
});
Note: It's a good idea to use associative array as #Tony noticed below to be sure which filter is for which database table attribute in your server side script.

You will need to write some code in any cases, but you can reduce it, for example like this:
$("#categories").change(function() {
uri = "myurl";
var filters = {
status: $("#statusfilter").val(),
category: $("#categories").val(),
network: $("#networksfilter").val(),
prod_type: $("#prodtypefilter").val()
}; // order is important
loadData(filters );
});
loadData(filters) {
var url = '';
for (var filterName in filters)
url += '/' + (filters[filterName] || 'any'); // here some def value needed
url = url.substring(1); // cut first slash
$('#userdata').load(url);
}
EDIT
Or even like this:
loadData(filters) {
var url = Object.keys(filters).map(function(el) {
return filters[el] || 'any';
}).join('/');
$('#userdata').load(url);
}

javascript update controls onload

iv'e got 2 html pages
one performs a "get" method on the other
these pages are duplicates in that they own they both poses a form with the same control types
and control names
when i submit my form from the source page my url string consist of the values appended together after a '?' char
....?txtName=era&txtAge=28&gender=male&langHe=on&langEn=on&select=1
in the detestation page onload i call a function which splits the control names and their values and sets them
// this is called from <body onload="f();">
function f() {
var st = new String(location.search);
st = st.substring(1, st.length);
var input = st.split('&');
var value;
var ctrl;
var val;
var _control;
for (var i = 0; i < input.length; i++)
{
value = input[i].substring(0, input[i].length);
ctrl = value.substring(0, value.indexOf('='));
val = value.substring(value.indexOf('=') + 1, value.length);
_control = document.getElementsByName(ctrl);
_control.value = val;
}
}
i debugged this function and checked that every thing is put in to place as it should
the problem is that after the value are set to the controls
they do not appear on the page , as if they didn't get set at all
additionally in Google chrome i get a "Aw,Snap!" Error after these actions (Aw Snap happens only when i debug )
i'm new to java-script and i'm guessing there's a problem with the way i'm assigning these values , i tried also just the first control which is a text type input and it also does not get updated .
any idea's on why this doesn't work ?
thanks in advance
eran.

Try changing the last line to:
_control[0].value = val;
UPDATE:
It would be a lot easier if you used jQuery:
$('[name='+ctrl+']').val(val);
