Understand the Anatomy of an XSLT Stylesheet
Get acquainted with the basic elements of an XSLT stylesheet.
You had a close brush with XSLT in the hack that discussed converting text to XML [Hack #18] , but you didn’t see much more than the stylesheet’s name. Here is the complete stylesheet, time.xsl :
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="Import">
<xsl:apply-templates select="Row"/>
</xsl:template>
<xsl:template match="Row">
<time timezone="{@timezone}">
<xsl:copy-of select="hour|minute|second"/>
<xsl:apply-templates select="atomic"/>
</time>
</xsl:template>
<xsl:template match="atomic">
<xsl:copy>
<xsl:attribute name="signal">true</xsl:attribute>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>The Document Element
An XSLT stylesheet has two possible
document elements,
stylesheet
and transform (see
line 1). Both have identical attributes; in fact, the only difference
between the two is that they have different names, but
stylesheet seems more popular with developers than
transform.
The version attribute is required. Some XSLT
processors support a value of 1.1 or 2.0, in support of those
versions of the XSLT specs, but 1.0 is the most commonly used value.
(Version 1.1 of XSLT is not and will never be a W3C recommendation,
so any support for it is processor-dependent.) The namespace
declaration is also required if you want an XSLT processor to
recognize the XSLT markup. The namespace name for XSLT 1.0 is
