Getting and using the filename in a regex expression

[jiembe]

I want to use the filename to add an id to an expression but I don't know how and I can't find the answer on the web.

For example: I'm in the file name File001.html

I want a function to modify this string: ' ></h1>'
to get this string: 'id="File001"></h1>'
and do it recursively.

Thank you. (I hope I'm in the good forum)

Thank you.

I should have found it.

Now if only I can find to use it. Try and error will do as always !

(later) Stupidly easy.
