The regex for matching the device tree path is different from a path.

the pathname convention is:

node-name@unit-address

The characters allowed for node-name/unit-name are:
        0-9 a-z A-Z , . _ + -

Although the @unit-address may be ommitted.

So the regex should be something like:
"/"({alnum}|['\._\+\-@])*
