Unique element ID to reference later
<p>I'm trying to figure out a method of storing a unique reference to each  tag on a particular page. I won't have any ability to edit the page content and I'll the generated UID to stay the same on every page refresh.</p>

<p>Since browsers don't generate any kind of UID for elements, I was thinking that the only method to do this would be to execute a script which walks the DOM and creates a UID for each  it comes across. I don't know how accurate this will be, especially considering I'll need to ensure it creates the same UID for the tag each time the script crawls the page.</p>

<p>Can anyone think of any other, more accurate ways of mapping a page? </p>

<p>Many thanks.</p>
