I'm making a dynamic template that has several buttons with icons. I want to bind the icon paths to string params of the template, but only if the path is valid.

The only solution I can think of to check this is to read the svg files as a string and search the string for the icon name, kind of like this solution for view path:

I really don't like this solution though, is there another expression or scripting function I can use to valid the icon path?

If the icon path doesn't exist, it won't show anything. Is that an issue?

Yep, just getting carried away with validating
