Then apply templates to the product elements as well as the category
elements, and have a template for the product elements that creates a
product element with the name and id inside:

<xsl:template match="category">
  <xsl:copy>
    <xsl:copy-of select="id" />
    <xsl:copy-of select="name" />
    <xsl:apply-templates select="category | product" />
  </xsl:copy>
</xsl:template>

<xsl:template match="product">
  <xsl:copy>
    <xsl:copy-of select="id" />
    <xsl:copy-of select="name" />
  </xsl:copy>
</xsl:template>

(You could probably actually combine these templates into:

<xsl:template match="category | product">
  <xsl:copy>
    <xsl:copy-of select="id" />
    <xsl:copy-of select="name" />
    <xsl:apply-templates select="category | product" />
  </xsl:copy>
</xsl:template>

if you wanted.)

The general pattern in XSLT is that for each element in your XML you
have a template that shows how to map from that element to the element
that you want to create in the result.

Cheers,
