Perl & XML
by Erik T. Ray, Jason McIntosh

The following errata were *corrected* in the 7/04 reprint:

Here's a key to the markup:
	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem



(5)  1st code segment, line 10
<email>i-like-cheese@jmac.org</email> 

NOW READS:
<email>joewrigley@jmac.org</email>


(6)  Paragraph starting with "In the Perl world";
"through the use pragma" NOW READS  "through a use
directive".


(21)  Paragraph starting with :Finally";
"&#00DC;" HAS BEEN CHANGED to "&#x00DC"


[23]  1st paragraph;
"The answer is: declare the decoding in the XML declaration."

NOW READS:
"The answer is: declare the encoding in the XML declaration."


(24)  1st sentence;
Spurious "hackers" HAS BEEN DELETED.


{29}  4th paragraph, lines 3,5;

max-inclusive  NOW READS  maxExclusive
max-length  NOW READS  maxLength


(32)  Step 7 of tranformation list;

<xsl:apply-templates/>



{44}  Example 3-2, print statements on lines 12 and 14;

NOW READ:
     print STDERR "\nERROR in '$xmlfile':\n$@\n";
     print STDERR "'$xmlfile' is well-formed\n";


(52) IN PRINT: Second paragraph, last sentence;
"...thinking in standards-complaint ways."

NOW READS:
"...thinking in standards-compliant ways."


[53]  First example (top of page);
  return unless ($node->nodeType eq &XML_ELEMENT_NODE);

NOW READS:
   return unless ($node->nodeType eq XML_ELEMENT_NODE() );



(53)  code example in sub{} at top of page;
I could not get Example 3-6 to work unless I changed the "return" line
to be:

return unless (ref($node) eq 'XML::LibXML::Element');

[note: I had previously changed the earlier error (rm the "&"), but
this did not
matter.]

This problem is CORRECTED with the CHANGE to page 53 noted above.
