Extracting from pipe delimited file.
Hey,

I am new to regualar expression. I wanted to extract the information from a pipe delimited file which has some entries like

L|S2CMG1B|||-11178399||1|-8.65|IRCSH|BOND||||N|S|IRDL|AUD||CRP|STD|CRP|M|0|1|||CSH||||OTHER|01|DE|KFW|50418Y9T5|||||||||||2||| |||

In this I want to extract the parts between various pipes. The entries between pipe may or may not be null.
I have got that using split function but I want to try with Regular expressions to check for the performance difference between split and regular expressions.
The entries between pipes in going to be alphanumeric.

Can anyone please help me with that?

Thanks
lee

NAME

       streampipes - force all pipes to be STREAMS-based

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
DESCRIPTION

       This tunable determines the type of pipe that is created by the system call.  If set to the default value of zero, all pipes created by are
       normal HP-UX file-system pipes.	If the value is non-zero, creates STREAMS-based pipes, and STREAMS modules can be pushed onto the  result-
       ing stream.

       If this tunable is set to a non-zero value, the and module and driver must be configured in file

   Who Is Expected to Change This Tunable?
       Any customer.

   Restrictions on Changing
       Changes to this tunable take effect at next reboot.

   When Should the Tunable Be Turned On?
       If the customer uses applications that require STREAMS-based pipes, this tunable should be turned on.

   What Are the Side Effects of Turning the Tunable On?
       STREAMS-based pipes performance may differ from normal file system pipes.

   When Should the Tunable Be Turned Off?
       If the customer does not need the STREAMS-based pipes, this tunable should be turned off.

   What Are the Side Effects of Turning the Tunable Off?
       Applications that try to push STREAMS modules onto the pipe will fail.

   What Other Tunable Should Be Changed at the Same Time as This One?
       If this tunable is set to a non-zero value, the and module and driver must be configured in the file

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
