XSLT 1.0 is very limited for this kind of string manipulation, but you can
often achieve what you need with the help of translate(). For example,
translate($x, '012345789', '9999999999') will convert all digits to 9s,
which makes  it possible to use substring-before(translate($x, '012345789',
'9999999999'), '9') to find the text that precedes the first digit. Or given
the string "51a", you can extract the "a" using translate($x, '0123456789',
'').
