use attribute value as regular expression in stringsearcher
I think this should be easy but cannot work out how to use an attribute value as the regular expression in the string searcher transformer.

I think it's possible in general. For example:
Attributes of input feature (name: value)
_src: abc123
_regex: ^([a-z]+)([0-9]+)$
Parameter settings of the StringSearcher (refer to the attributes)
Search In: _src
Regular Expression: _regex
Logged result
Attribute(encoded: utf-8): `_matched_characters' has value `abc123'
Attribute(encoded: utf-8): `_matched_parts{0}' has value `abc'
Attribute(encoded: utf-8): `_matched_parts{1}' has value `123'
Attribute(encoded: utf-8): `_regex' has value `^([a-z]+)([0-9]+)$'
Attribute(encoded: utf-8): `_src' has value `abc123'
How's your actual situation?
