The Default Template Rule for Text and Attribute Nodes

The most basic built-in template rule copies the value of text and attribute nodes into the output document. It looks like this:

<xsl:template match="text( )|@*">
  <xsl:value-of select="."/>
</xsl:template>

The text( ) node test is a pattern matching all text nodes, just as first_name is a pattern matching all first_name element nodes. @* is a pattern matching all attribute nodes. The vertical bar combines these two patterns so that the template rule matches both text and attribute nodes. The rule’s template says that whenever a text or attribute node is matched, the processor should output the value of that node. For a text node, this value is simply the text in the node. For an attribute, this value is the attribute value but not the name.

Example 8-10 is an XSLT stylesheet that pulls the birth and death dates out of the born and died attributes in Example 8-1. The default template rule for attributes takes the value of the attributes, but an explicit rule selects those values. The @ sign in @born and @died indicates that these are attributes of the matched element rather than child elements.

<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="people"> <html> <head><title>Famous Scientists</title></head> <body> <dl> <xsl:apply-templates/> </dl> </body> </html> </xsl:template> <xsl:template ...
