( #3333=superdoc: print w/replies, xml ) Need Help??

Oh. The file is being written to, but you can't read it because it was opened for append but not read (mode ">>" instead of "+>>"), and also because, due again to the append access, it is already positioned to the end of file when you do the first read.

If you change the open mode from ">>" to "+>>", and insert   seek FH5, 0, 0 or die "Seek failed, $!"; just before  while (<FH5>) it should work.

Another way would be to close FH5 and then reopen it for input (mode "<") just before trying to read it.

    [Corion]: I usually expect fixed header names, but am sometimes lenient in the order of columns. But changing the report titles often sounds to me as if you are not the sole consument of the export ;)
    [shmem]: perldigious: as always - if it ain't broke, don't fix it. Ther must be a very compelling reason for changing column names in a database. Those are rare.
    [Corion]: If you have whitespace in the column names in the database, whap the DBAs ;)
    [shmem]: It's common for some vendors to have column names such as WRSTVG or some other such whizzbang, and another table where these names are mapped to something meaningful depending on how you look at the data
    [shmem]: afair in SAP that occurs all the time
