You would have to post some sample code and the specific error text. "Its giving me error" doesn't really say much.

Just for grins:

#!/usr/bin/perl
my $foo="|abcxyz||fiuhs|";
for (split(/\|/,$foo)) {
   print "field is [$_]\n";
}
[download]

Creates this output:

field is []
field is [abcxyz]
field is []
field is [fiuhs]
[download]

Which seems reasonable to me...
