Ok, I'm writing an apxl to html converter and I have one little problem: I need to open a filehandle in one sub, use it in several others, and then close it in a different sub yet. I'd pass it as a parameter, but all the subs are actually called by XML::Parser, so I don't get to choose the parameter list. Therefore I'm trying to keep it in a 'global' (package-level) variable, but I can't seem to get it to work. ;-)
Here's what I'm trying at the moment: -------------
my $curFile; # The current output file. my $html; # The HTML Stream.
# Some code....
# The start of a slide.
sub slide
{
# Open/create the file.
$slideNum++; # Incriment the slide number.
open CURFILE, "> slide$slideNum.html" or warn "Could not open slide$slideNum.html: $!";
$curFile = \*CURFILE;
$html = new HTML::Stream($curFile);
# More code... (All from HTML::Stream) }
# The end of a slide.
sub slide_
{
# Closing code...
# Close the file.
close $curFile;
}-----------
This goes through with no warnings or errors, but the code in slide_() does not have access to the file opened in slide(). (It does get run, I tested that.) Anyone have any ideas (other than re-opening it in every sub, which I could probably do as a last resort...)?
