& XSLT Hi,
I'm just trying to use the getLength function off of a xml node, but
get an error when used it.

the error is saying: "can't call method "getLength" without a package
or object reference"

and this is part of my codes.

my @root = $doc-> getElementsByTagName("environmentConfig");
my $length = @root-> getLength;
my $sample = $doc-> getDocumentElement();
my $children = $sample-> getChildNodes();
print "\nThe root element is ", $sample-> getNodeName(), ".\n";

I think I'm using the getLength function in right way but could anyone
tell me if it is wrong? also is there an external package I should
include to be able to use this function?

Thank you.
