How to use RegExp replace in Eclipse

Here is a quick tip for when you want to replace some text in your code.

Say that you have many HTML attributes like name="email" and you want to replace them with name="<?= $field['email']['name']; ?>". Then you must search for name="(w+?)" and replace with name="<?= $field['1']['name'] ?>". Note that you need to escape the $ with a backslash for Eclipse to do its work. If you omit it, Eclipse will simply not work and not complain.
