Answer 1

is there any operation such as trim in xslt?

I. XSLT 1.0

No, and it is rather difficult to perform "trim" in XSLT 1.0.

Here is the trim function/template from FXSL:

  

  

  
  
    '
        
    '
  

When this transformation is performed (you have to download at least a few other stylesheet modules, which comprise the complete import tree) on this XML document:

   This is    some text   

the wanted, correct result is produced:

'This is    some text'

II In XSLT 2.0 / XPath 2.0

Still a little bit tricky, but very short:

     if (string(.))
       then replace(., '^\s*(.+?)\s*$', '$1')
       else ()

Here is the complete, corresponding transformation:

    

 
     ""
 

and when applied on the same XML document (above), the same correct result is produced:

"This is    some text"
