Hi Prabhu,
 
     Lot of thanks for the response.
 
    Through XPath I mean the application (where selectnodes are used)
cannot use all the features of XPath like selection construct, iteration
etc. (through the documents I have seen, if we can please suggest the
way) but XSLT has the facility to use them that is why I was thinking to
use XSLT and as far as Xslerator is concerned I found at alphaworks that
it can be integrated with other applications. 
 
    If all the XPath constructs and functions are allowed from within
the application, may be my purpose will be solved. However is their any
other algorithms/ methods for faster retrieval of queries.
 
 
 
Regards,
 
Pritam.
