I want to add something like this to the footer so readers can contact me if there's a problem with the page:
Elliotte Rusty Harold<br/> elharo@metalab.unc.edu
This information comes from the maintainer element:
<maintainer email="elharo@metalab.unc.edu"
url="http://www.macfaq.com/personal.html">
<name>
<first_name>Elliotte</first_name>
<middle_name>Rusty</middle_name>
<last_name>Harold</last_name>
</name>
</maintainer>
So we need a way to get content from attributes in the input document.
This is accomplished by prefixing the attribute name with @.
<xsl:template match="catalog">
<head>
<title><xsl:value-of select="category"/></title>
</head>
<body>
<h1><xsl:value-of select="category"/></h1>
<xsl:apply-templates select="composition"/>
<hr/>
Copyright <xsl:value-of select="copyright"/><br/>
Last Modified: <xsl:value-of select="last_updated"/><br/>
<xsl:apply-templates select="maintainer"/>
</body>
</xsl:template>
<xsl:template match="maintainer">
<xsl:value-of select="name"/><br/>
<xsl:value-of select="@email"/>
</xsl:template>
