Supposing I have a bunch of file paths, similar to:

• /Volumes/A//Array/05_SCRIPTS/staging/tree/04_OUTPUTS/MPEG_FF_PS_wCropping/01_NBC_Youtube/Backlog/Archive/LawAndOrder_S20

• /Volumes/A//AArray/05_SCRIPTS/staging/tree/04_OUTPUTS/MPEG_FF_PS_wCropping/01_NBC_Youtube/Backlog/Archive/LawAndOrder_S20/nbcnetwork-pds-E8818-US-insert-20121020

How would I highlight all matches of specific text on the page. For example, if "04" was what I was looking for, it would do something like:

$(source).find('04').addClass('highlight');

This is pseudocode that is probably way off the mark, but this is what I'm looking to do.

var t = $(source).html();
t = t.replace(/04/g, "<span class='highlight'>04</span>");
$(source).html(t);
