text between tag manipulation (HTML)

Hi.

I'm trying to insert on-screen sequential numbers (in locally saved
web documents) to let non-web designers comment on the elements/tags.
Additionally, these numbers act as a pseudo-line/reference number.

Just to be clear, if I have:
<body>
Lorem ipsum dolor
Proin sed sapien
</body>

I'm trying to generate:
<body>
1 Lorem ipsum 2 dolor
3 Proin sed sapien
</body>

I'm familiar with opening/saving files, loops, and regex, however,
working with/seamless massaging the text between tags, (and not
damaging the nested tag structure) is beyond me. How could I
manipulate HTML final rendered, on screen text, but respect the HTML
source?

(I'm having a lot of trouble forming a regex that honors tags within tags.)

It is a bad idea to try to manipulate HTML using regular expressions:
you should parse the HTML into a document object and manipulate that.

This looks to me like a job for JavaScript. Just find all the text
nodes in the document body and precede them with an incrementing
sequence of numbers.

Perhaps I have missed something as I don't understand what you mean by

> manipulate HTML final rendered, on screen text

as the rendered display is clearly not HTML any longer. Also

> respect the HTML source

puzzles me. Are you hoping to annotate the display without modifying the
HTML?

Anyway, I hope this helps.

Sorry, that wasn't worded clearly.

I'm trying to manipulate the source code, but I don't want to destroy
the tags or the structure of the document.
