compare string to a list of other strings

Hi,

I'm using XSLT 2.0 and Saxon 9.
I want to check if a string starts with on of a whole bunch of strings.

For example:

This are the strings: estg, abgb, eg, ...

I want to check if another string starts with estg, abgb oder eg.
Now i could do a very long line of "starts-with() or starts-with()" but
I'm sure there is a better way to do it right ?!

Kind regards
