How can I convert this string (between '<' and '>' to a tag?
Probably it's a better idea to define the replacement string as <x id="XRef" equiv-text="\2">, to make it clear, which kind of transformation has taken place.

After finishing the project, you'll have to use the external editor again, to convert the x id's to the original strings.
Use an editor to find and replace the string to mask:

Note that the original page number is visible in the project segments pane.
Igor, can we please get a feature to allow us to do useful masking operations like these?
