XML results questions

I'm retrieving an XML result from a website and the the result changes
according to the number of Items returned.
if only one item returned the XML use a hash to hold the name and
value, however if more then one Item was returned it uses an Array to
hold all the results.
I'm trying to right a foreach statement to extract all the information
and when I get one Item I get an error that this is not an Aray
referance (which is obvius).
does anyone have a seggestion, how can I find if the results are in an
array or a hash?

Thanks
Arik

Some subs return either a scalar or list based on context
which may be the problem you are having. If you posted
the code which is returning the morphing value and the
way that you are calling it then someone might be able
to help you.

Since you're dealing with references, this is easy.

There's a built-in function (ref) which does precisely this.
if ( ref($r) eq 'HASH' ) {
print "r is a reference to a hash.\n";
}
else if ( ref($r) eq 'ARRAY' ) {
print "\$r is an array ref.\n";
}

In addition, if you're using XML::Simple, read the documentation for
ForceArray.

You keep claiming that you have XML questions but your questions always
turn out to be basic language related questions.

You should check out the table of contents of Perl documentation installed
on your computer and read at least perlsyn, perldata, perlvar and perlfaq
for starters.

Then, you should take a look at perldsc and perlref at a minimum.

Thanks for pointing me out to the documentation I'll definitely look
this up, I sure hope though that these suggestions come in good spirit
