I want to remove the BLANK lines from this file. I am reading a file of size atleast 1 GB.
So kindly let me know which would be the best way to quickly reduce the processing time when removing the blanks.
If you can give me an example that would also be fine.
Regards
Dhana

SOAPSH(1p) User Contributed Perl Documentation SOAPSH(1p)
NAME
SOAPsh - Interactive shell for SOAP calls
SYNOPSIS
perl SOAPsh http://services.soaplite.com/examples.cgi http://www.soaplite.com/My/Examples
> getStateName(2)
> getStateNames(1,2,3,7)
> getStateList([1,9])
> getStateStruct({a=>1, b=>24})
> Ctrl-D (Ctrl-Z on Windows)
or
# all parameters after uri will be executed as methods
perl SOAPsh http://soap.4s4c.com/ssss4c/soap.asp http://simon.fell.com/calc doubler([10,20,30])
> Ctrl-D (Ctrl-Z on Windows)
DESCRIPTION
SOAPsh is a shell for making SOAP calls. It takes two parameters: mandatory endpoint and optional uri (actually it will tell you about it
if you try to run it). Additional commands can follow.
After that you'll be able to run any methods of SOAP::Lite, like autotype, readable, encoding, etc. You can run it the same way as you do
it in your Perl script. You'll see output from method, result of SOAP call, detailed info on SOAP faulure or transport error.
For full list of available methods see documentation for SOAP::Lite.
Along with methods of SOAP::Lite you'll be able (and that's much more interesting) run any SOAP methods you know about on remote server and
see processed results. You can even switch on debugging (with call something like: "on_debug(sub{print@_})") and see SOAP code with headers
sent and received.
