Hi Tom-
indeed, the new reader complains because what you feed to it is not a 
well-formed XML.

yes, for example e.g. using the same reader and checking the value of depth(). 
readInnerXML and readOuterXML are not meant to be used for this purpose.

Yes, see the following code:

#_____________

my $xml  = <<'EOF';
<parent a='A' b='B'> 
  <child a='A' b='B'> 
    <gchild a='A' b='B'> a</gchild>
  </child> 
</parent> 
EOF

use XML::LibXML;
use XML::LibXML::Reader;
my $r = XML::LibXML::Reader-> new(string => $xml);
while ($r-> read) {
  if ($r-> nodeType == XML_READER_TYPE_ELEMENT) {
    print "-----------------\n";
    print "Element ". $r-> name,"\n";

    # several ways of reading attributes:
    # read all attributes:
    if ($r-> moveToFirstAttribute) {
      do {{
	print "Attribute ",$r-> name(), " => ",$r->value,"\n";
      }} while ($r-> moveToNextAttribute);
      $r-> moveToElement;
    }
    # back at the element
    # ...

    # read a specific attribute:
    print "----\n";
    print "Attribute b: ",$r-> getAttribute('b'),"\n";
  }
}
