Answer 1

This short and simple (no explicit conditional instructions) XSLT 1.0 transformation:

when applied on the provided XML document (corrected for well-formedness):

    
        example
    
    
        hello
    
    
        25
    
    
        1
    

produces the wanted, correct result:

   
      example hello 25 1
   

---

II. XSLT 2.0 solution

When this transformation is applied on the same XML document (above), the same correct result is produced:

   
      example hello 25 1
   

Explanation: Using the fact that the default value for the separator attribute of xsl:value-of is a single space.
