What's a consistent way to find the origin of data from a certain web app?
Context: I'm working on a native app, and am trying to capture data from a publicly hosted JavaScript app. But I can't figure out where exactly the data I'm looking for originates from. The Document Object Model is quite chaotic.
Consider:
<html>
<body>
<script src="app.js"></script>
</body>
</html>
and consider app.js:
// super complex app starts here
var hello = "hello world";
document.write(hello);
// super complex app ends here
Let's say app.js is a super complex compressed JS app, that somehow writes "hello world" to the document but we have no immediate idea where it's coming from...
What's a definitive way to figure out where "hello world" first gets mentioned to the DOM?
Web inspector seems unable to search all downloaded files for "hello world"...
