- Launch TextWrangler.
- Select Find... from the Search menu.
- In the 'Search for' field at the top of the dialog, type autoplay=false.
- In the 'Replace with' field, type autoplay=true.
- Check the Multi File Search Box.
- Click the Other... button on the right-hand side
- Select your iWeb folder using the following path: iDisk/Web/Sites/iWeb.
- You might want to click the Saved Search Sources and choose Remember this Set. This helps for future reference, but is not necessary for the script.
- Hit the Replace All button.
- Hit the Proceed button in the dialog box that appears. I wouldn't recommend changing any of these settings.
- Hit Save when it replaces the found text in a webpage. The Save box will appear for each web page you have created with embedded music.
- When finished, Quit TextWrangler.
BTW, you might want to run TextWrangler first once you download it to register and install all of its components. Then you can quit it and run the Script Editor.
Hopefully this will help some people, and you can obviously customize the Find command to do a whole lot more. I just wanted songs to autoplay.
