Hey Thanks a lot. I got it. I greatly appreciate your help. I have another small issue. when I get the array of something I extract, I try to print them using the code

if (ref($bar) eq "ARRAY") {
      
    foreach my $q (@$bar){
      print FH $q ,",";
    }
    } else {
      print FH $bar;
    }

But, this doesn't seem to be of help. I want to do something that if its an array separate them by ',' else just print the individual without ','. But when I use the above code it also prints the single element with a ',' and in an array it gives ',' after the last element. I know how to solve the same issue in XSLT its something like

<xsl:test if position() != last()>
<xsl:value-of select="."/>;
</xsl:test>
<xsl:test if position() = last()>
<xsl:value-of select="."/>
</xsl:test>

Thus everything is separated by ';' except for the last element and if its only a single element then it gets printed as it is. Can I do something same in perl, can you please help. Thank you, Sammed
