math extract
In XSLT 2.0, you can extract the numbers with

replace(@result, '^.*\[Total] = ([0-9]*).*$', '$1')

and

replace(@result, '^.*\[Count] = ([0-9]*).*$', '$1')

In XSLT 1.0, use a sequence of calls on substring-after and
substring-before.

A lot depends on quite how flexible you want to be in accepting variations
on this input. If you just want to extract two numbers from a string, and
you know there are spaces around them, you could do

translate($in, 'ABCDE..Zabcde..z:=[]', '')

to get rid of everything except spaces and digits and ".",

then normalize-space(),

then substring-after($in, ' ')
and substring-before($in, ' ')
