Thanks for the guidance. I do have some code, but I didn't figure it would help to see it if I didn't provide the file it's trying to extract data from. But I'll place it here anyway. <\p>

while(<STDIN>)

    @section = split /Class: Invoice/, $_;
    @AdminData = split /\n/, $section[0];
    @BodyTemp = split /Administrative Data:/, $_;
    @Body = split /Reply: click here/, $BodyTemp[0];
    
    @Splitterhold = split/Payment Detail - Payment ID /, $_;
    
    foreach $Splitterhold(@Splitterhold)
    {
    $Splitterhold =~ s/InvoiceDate /Invoice Dateĉ /g;
    $Splitterhold =~ s/Customer ID /CustomerIDĉ /g;
