To add to what Graham said, probably the easiest way to handle this is to go to Special:Preferences and under Editing, change to Source Editor.

When you go into edit, you will have the source code for your page.

If you copy and paste that into a good text editor such as BBEdit for Mac (you can use for free, and Notepad++ for Windows, you can then do find and replace. (Anyone using Linux probably knows way more than I do....)

Once you finish the edits in the text editor, do a copy paste back into your edit page and then publish.
