Re^4: peek at STDIN, to determine data type and then pass STDIN to a parser

Okay - I have gotten your code to work, and to do what I want. Now this may be a beginners question - but:

How on earth do I get XML::Twig's parse function to use the iterator instead of a filehandle?

my $inputHandle = create_iterator();
$t->parse (<$inputHandle>);
[download]

exits with error message "Not a GLOB reference at ./script.pl line xy.".

And

$t->parse ($inputHandle);
[download]

spits out: "not well-formed (invalid token) at line 1, column 4, byte 4 at /usr/lib/x86_64-linux-gnu/perl5/5.20/XML/Parser.pm line 187. at ./script.pl line xy."

So how do I typecast the iterator in order to treat it like a file handle?

Ok, I have had a chance to look at this - my statement above about it "treat it as just a file handle" is not quite accurate. It needs a little more support to make it look like an IO::Handle or a tied file handle. I am considering a self-project to be able to export an Iterator::Simple object as an IO::Handle object. I have been using the iterators with the `->next()` or `<$iterator>` syntax, so stating that they just behave like a file handle is definitely a mea culpa. Given a couple of days perhaps I can have something available that will wrap an iterator as a globish object. I will update here if/when that happens. --MidLifeXis	[reply] [d/l] [select]

If you could find a way to do this that would be much appreciated. I would try it myself, but I am afraid I am still way too clueless about the lower level mechanics of perl :)	[reply]

I understand you've probably been too busy to get back to this. However, the idea and approach seemed very valuable, and I would therefore like to bump the topic, in case someone has the time and interest to come up with a solution to wrap the above iterator approach in a glob like object. Anyone? :)	[reply]
