Cool - lists are a great help.

my $name = $element->getAttribute('name');

See the README, section 8.3)
# returns a reference to a XML::Xerces::DOM_NamedNodeMap
my $attr_map_ref = $element_node->getAttributes();
# returns a hash of the attributes
my %attrs = $element_node->getAttributes();
put the method in scalar context and you get an object, put it in list
context and you get a Perl hash - I prefer the Perl hash.

Two answers:
1) $node->getNodeType eq $XML::Xerces::DOMNode::ELEMENT_NODE;
filter on the node type and throw away text nodes
2) if your XML file has a DTD you can can set a parser attribute to
ignore optional whitespace:
my $parser = XML::Xerces::AbstractDOMParser->new();
$parser->setIncludeIgnorableWhitespace(0);
now you will not get the newlines, but this only works if your XML
files use a DTD.
