You can’t really use a regular expression in a selector but CSS selectors are powerful enough for your need with a “starts with” syntax inspired by regexes.
You can use a substring matching attribute selectors : link[type^=service]
Reads “Nodes of type link
with an attribute type
starting with “service”
From the formal specification:
[att^=val]
Represents an element with the att attribute whose value begins with the prefix “val”. If “val” is the empty string then the selector does not represent anything.
