D'oh, just realised you can do it in one line with JQuery, which I am using in my project.

$('#my-element').text($('#my-element').html());

if at all you need to store the value in a variable and then store that to a field for the database, here is the code

var textVal = $('<div />').text($(this).contents().find("body").html()); $("#dest_field).val(textVal .html());
All HTML special characters can have their numeric values used instead of their normal symbols. So > can also be represented by >. Javascript's encodeURI() converts characters into these numbers, but uses the HEX versions. I've made a simple function using this idea to escape HTML. I tried doing it using back references, but couldn't get it working.
