Question

I want to remove characters other than alphabets from a string in XSLT. For example

O\'Niel = ONiel


        

Answer 1

Here's a 2.0 option:

EDIT: Sorry...the 1.0 requirement was added after I started on my answer.

XML

  O'Niel
  St Peter
  A.David

XSLT 2.0

Output

   ONiel
   StPeter
   ADavid

Here are a couple more ways of using replace()...

Using "i" (case-insensitive mode) flag:

replace(.,'[^A-Z]','','i')

Using category escapes:

replace(.,'\P{L}','')
