Re: Re: For loop problem

Thanks for your advice which has raised a point and a question in my mind. Point: The tags are on the inner most left side of the text file. I need $d and $key to be an exact numeric match. Question: Does the if ($d =~ /^$key$/){ not cover this in every circumstance? Point: I tried to do a numeric match but the $key is treated as a string.

Something like this would probably make more sense (if I understand your situation correctly): `open( OUTPUT_XML_A_OPEN, $output_XML_A_open ); open( NEW_OUTPUT_XML_A, "+>>", $new_output_xml_a ); for $d ( 1..9 ) { seek( OUTPUT_XML_A_OPEN, 0, 0 ); while (<OUTPUT_XML_A_OPEN>) { chomp; # I'm leaving out a lot of your debugging stuff if( /^$d\D/ ) { # does this line start with "$d"? print NEW_OUTPUT_XML_A; } } }` [download] As I understand it, you are trying to find lines in the input file that begin with single-digit numbers, and print these to an output file in sorted order (all the "1" lines first, then all the "2" lines, etc), without worrying about any sub-sort ordering (all the "1" lines can be in any order). In that regard, I wonder why you open the output file for "append" access (">>") -- and why you open it for both read and write access (using "+"), when you don't really need to read it here?

open( OUTPUT_XML_A_OPEN, $output_XML_A_open );
open( NEW_OUTPUT_XML_A, "+>>", $new_output_xml_a );
for $d ( 1..9 ) {
  seek( OUTPUT_XML_A_OPEN, 0, 0 );
  while (<OUTPUT_XML_A_OPEN>) {
    chomp;   # I'm leaving out a lot of your debugging stuff
    if( /^$d\D/ ) {  # does this line start with "$d"?
      print NEW_OUTPUT_XML_A;
    }
  }
}
