Solution

1. corrected mutate prefixes
2. found the real mistakes
3. figured that the current XPATh can not do it
4. here is the new XPATH

for this doc

this works

'sichtbar:',

for $skonto in  tokenize(/root/b[2] , '(\r?\n)')[starts-with( normalize-space(.) , '#')]  return normalize-space ($skonto),



string-join('und jetzt blind'),

every $line 
  in /root/tokenize(b[2] , '(\r?\n)')[starts-with( normalize-space(.) , '#')] 
  satisfies matches(
                     normalize-space ($line),
                     '#(SKONTO|VERZUG)#TAGE=([0-9]+#PROZENT=[0-9]+\.[0-9]{2})(#BASISBETRAG=-?[0-9]+\.[0-9]{2})?#$'
                   )  

the ever #line is the meat before ist just for debugging
