How do I use a regular expression in XSLT 1.0?

Question

I am using XSLT 1.0. My input information may contain these values

123-00




        

Answer 1

This solution really works in XSLT 1.0 (and is simpler, because it doesn't and needn't use the double-translate method.):

 
 

 

 

 

 
  
   

    Processing X
   
   
    Processing Y
   
  
 

when applied on the provided XML fragment -- made a well-formed XML document:

    
    123-00
    
    Abc-01
    
    --
    
    Z2-p01

the wanted, correct result is produced:

Processing Y


Processing X

Processing Y


Processing X

Do Note: Any attempt to use with a true XSLT 1.0 processor code like this (borrowed from another answer to this question) will fail with error:

because in XSLT 1.0 it is forbidden for a match pattern to contain a variable reference.
