Confirmed typos in the July 2005 1st edition:

p.20
Although the book shows you where to find a validating parser at this point, the current example cannot be checked for validity, because it has no DTD associated with it (see p.14). Validating parsers will come in handy later in the book, but for now if you run the current example XML file (the product listing), you'll get an avalanche of error messages, because the document does not provide a DTD for validation.
p.48 paragraph 2
"whenever there in only whitespace" should be "whenever there is only whitespace".

p.134 code listing 3
The template given here doesn't perform the sort as described. When $SORTBY is given as the value of the <xsl:sort> tag's select attribute, the style sheet simply evaluates the value of $SORTBY (which will always be the same) for each element in the list, which doesn't sort the list at all. To achieve the desired sort, you can use this template instead:

	<xsl:template match="sitemap">
		<ul>
      <xsl:choose>
        <xsl:when test="$SORTBY='type'">
          <xsl:apply-templates>
            <xsl:sort select="type" />
          </xsl:apply-templates>
        </xsl:when>
        <xsl:when test="$SORTBY='date'">
          <xsl:apply-templates>
            <xsl:sort select="created" />
          </xsl:apply-templates>
        </xsl:when>
        <xsl:otherwise>
          <xsl:apply-templates>
            <xsl:sort select="headline" />
          </xsl:apply-templates>
        </xsl:otherwise>
      </xsl:choose>
		</ul>
		<p><small>sorting by: <u><xsl:value-of select="$SORTBY"/></u></small></p>
	</xsl:template>
