Here's another example regarding your question:
aCell.xmlAttributes.item("attr_name").value; //works in CS3
aCell.parent.xmlAttributes.item("attr_name").value; //works in CC 2019
As far as I know (I can be wrong!), nothing has changed in InDesign since CS3 regarding XML so both lines should work in the same way in CS3 and, say, 2020.
Below is a screenshot of my previous test doc with only one change: I added the "attr_name" attribute to the parent of aCell which is Table in my case and assigned it t

It's always at the top of the script, like so:
The glue code is located here:
Make sure the path is correct. See 'Preprocessor directives' on page 233 in JS tools guide.
>> There is no reference to use of glue code.
See the XML Rules section in InDesign Scripting SDK. BTW, sample scripts are also provided there.
>> Since these are existing scripts, there are multiple areas I have to change the way XML is parsed in CC 2019. Any idea how to fix this issue?
You can open all your scripts in ESTK and make a change in all open docs in one go, like so:
It's hard for me to tell you what goes wrong and how to fix it without having the script in question and a doc for testing.
Looking at your code, I guess aCell is a cell in a table. Right?
Then cell has no xmlAttributes property! Instead you should use associatedXMLElement which has it. Let's assume a cell is selected:
Then the following code gets its attribute's value:
main();
function main() {
var aCell = app.selection[0];
var val = aCell.associatedXMLElement.xmlAttributes.item("attr_name").value;
}

aCell.parent.xmlAttributes.item("attr_name").value; //works in CC 2019

Below is a screenshot of my previous test doc with only one change: I added the "attr_name" attribute to the parent of aCell which is Table in my case and assigned it the value of "my_another_value".
So, both lines make sense if the XML elements have the attribute called "attr_name".
In my example, they have different values:
aCell ( I assume it's associated XML element of a cell) — my_attr_value
and its parent (table) — my_another_value
However, if the attribute with this exact name is missing, you'll get the Object is invalid error because indeed the object you reference is invalid.
To avoid such a situation, you can validate the reference to the attribule, like this:
main();
function main() {
var sel = app.selection[0]; // a cell is selected
var aCell = sel.associatedXMLElement;
var attr_1 = aCell.xmlAttributes.item("attr_name");
if (attr_1.isValid) {
var val_1 = aCell.xmlAttributes.item("attr_name").value;
}
var aTable = aCell.parent;
var attr_2 = aTable.xmlAttributes.item("attr_name");
if (attr_2.isValid) {
var val_2 = aTable.xmlAttributes.item("attr_name").value;
}
}
For example, here I removed the attribute from the table. Since the reference is invalid, line #15 (unlike #9) is skipped (note the green marker after the line number is missing).
Hope it's clear now.
