regex to change href link to lowercase

Question

I have pages with links like:

href="FileName-One-Example.html"

I need to a regular expression command with Notepad++ to change the case of the anything between href=" nad the ending " to lowercase, and leave everything before and after it in the page as is.

So the result is:

href="filename-one-example.html"

Answer 1

This is the correct regexp to use:

Find: (href=")([^"]*)
Replace: \1\L\2\E

Edit: changed the second \L to \E as suggested in the comments.
