Re: Writing a stylesheet to create another XML Documen

The "EXTRA STUFF" is a template matching the root node:

<xsl:template match="/">
  <xsl:for-each select="Tutorial/AuthorList/Author">
    <xsl:value-of select="Name" />
  </xsl:for-each>
</xsl:template>

When the processor starts its work, it begins at the root node of the
source document (in your case Tutorial.xml) and tries to find a
template that matches that root node. You've provided one for it here,
so this is the template that gets used to generate the output of the
transformation.

This template tells the processor to find all the Author elements
within the AuthorList within the Tutorial document element of
Tutorial.xml, then, for each of them, give the Name element child of
that Author.

However, in Tutorial.xml, the Author elements don't have Name element
children. So for each of the Author elements, you generate nothing.
And the output is therefore empty.

In other words, this "EXTRA STUFF" template is overriding everything
else in your stylesheet because it matches the root node of the source
document, and completely determines the result of the transformation.

I'm not sure what you wanted to achieve with this template. Possibly
you wanted to apply templates to the Author elements in Author.xml
(rather than copying them), and retrieve their Name element children
in that way. To do so, apply templates rather than copying the Author
elements, in a different mode than usual ('details' mode, say):

<xsl:template match="Author">
  <xsl:variable name="id" select="@id" />
  <xsl:for-each select="$authors">
    <xsl:apply-templates select="key('authors', $id)" mode="details" />
  </xsl:for-each>
</xsl:template>

and then have a template that matches Author elements in 'details'
mode, and gives their names:

<xsl:template match="Author" mode="details">
  <xsl:value-of select="Name" />
</xsl:template>

Cheers,

Jeni
