If you use EmEditor , press Ctrl + H to bring up the Replace dialog box, and enter:

Find : <(.*?)name="(.*?)">

Replace with : \\J "<\\1name=\\"\\2\\" newattribute=\\"\\2_" + (Math.floor(Math.random()*16)).toString(16) + (Math.floor(Math.random()*16)).toString(16) + (Math.floor(Math.random()*16)).toString(16) + (Math.floor(Math.random()*16)).toString(16) + "\\">"

set the Regular Expressions option, and click Replace All .

Explanation

\\J in the beginning of the Replace with string means that it is a JavaScript. \\1 and \\2 are back references referring to the first (.*?) and second (.*?) in the matched string. (Math.floor(Math.random()*16)).toString(16) is a random hexadecimal character.
