Convert XSLT 1.0 to 2.0
I need help converting an XSLT 1.0 file to 2.0 (so I can use the XSLT 2.0 replace() function call).
I've Googled, searched different books and SO with no success. I tried changing version="1.0" to 2.0 and changing html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en" to simply html but this all just results in XSLTProcessor errors.
Any help is greatly appreciated. Thanks in advance.
Here is my XSLT:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml" version="1.0">
<xsl:output method="xml" omit-xml-declaration="yes" indent="no"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" encoding="ISO-8859-1" />
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<xsl:element name="meta">
<xsl:attribute name="name">description</xsl:attribute>
<xsl:attribute name="content"><xsl:value-of select="EventList/title"/></xsl:attribute>
</xsl:element>
<xsl:element name="link"><xsl:attribute name="rel">alternate</xsl:attribute><xsl:attribute name="type">application/rss+xml</xsl:attribute><xsl:attribute name="title">RSS</xsl:attribute><xsl:attribute name="href"><xsl:value-of select="EventList/rssURL"/></xsl:attribute></xsl:element>

<body>
<xsl:apply-templates select="EventList" />
</body>
</html>
</xsl:template>
<xsl:template match="EventList">

<xsl:when test="Event">
<xsl:apply-templates select="Event"/>

<div class="eventItemText">

</div>
</div>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<!-- List -->
<xsl:template match="Event">

<!-- Title -->
<xsl:if test="eventStatus = 2"><xsl:value-of select="eventStatusString"/> - </xsl:if>
<xsl:element name="a"><xsl:attribute name="href">http://events.stanford.edu/e/e/?d=<xsl:value-of select="replace(detailpath,'/events/','')"/></xsl:attribute><xsl:attribute name="id"><xsl:value-of select="eventID"/></xsl:attribute><xsl:attribute name="rel">external</xsl:attribute>

<xsl:choose>
<xsl:when test="repeatRuleID > 0">

<xsl:if test="repeatRuleID=99">See details for exact dates and times.</xsl:if>
</xsl:when>
<xsl:otherwise>
<xsl:if test="string(beginDay)"><xsl:value-of select="beginDay"/>, </xsl:if>
<xsl:value-of select="beginDate"/>.
</xsl:otherwise>
</xsl:choose>
<xsl:if test="repeatRuleID!=99">
<xsl:if test="string(beginTime)">
<xsl:text disable-output-escaping="yes"></xsl:text><xsl:value-of select="beginTime"/>.
</xsl:if>
</xsl:if>
</xsl:element>
<!-- Location -->
<xsl:element name="a"><xsl:attribute name="href">http://events.stanford.edu/e/details.php?detailpath=<xsl:value-of select="detailpath"/></xsl:attribute><xsl:attribute name="rel">external</xsl:attribute>

</xsl:stylesheet>
In addition to changing the version attribute to '2.0', you need to feed your XSLT 2.0 code to an XSLT 2.0 processor.
At present, some of the XSLT 2.0 processors I use are:
Saxon 9.x
XQSharp 2.0
AltovaXML (XMLSpy)
Do note that an existing XSLT 1.0 code may behave differently under XSLT 2.0 -- the most obvious differences are that <xsl:value-of> no longer produces the string value of only the first node from a node-set, and that in XSLT 2.0 the dreaded RTF type has been eliminated, so no xxx:node-set() extension function is needed/provided.
You should also check the non normative XSLT 2.0 Appendix J Changes from XSLT 1.0 .
This section lists all known cases where a stylesheet that was valid (produced no errors) under XSLT 1.0, and whose behavior was fully specified by XSLT 1.0, will produce different results under XSLT 2.0.
While you're converting the code, you should get rid of those ugly disable-output-escaping="yes" attributes. They are almost certainly not wanted. The use of this attribute usually indicates that it was written by a novice with a poor understanding of the language. This also applies to the use of verbose constructs like
<xsl:element name="a"><xsl:attribute name="href">http://events.stanford.edu/e/e/?d=<xsl:value-of select="replace(detailpath,'/events/','')"/></xsl:attribute><xsl:attribute name="id"><xsl:value-of select="eventID"/></xsl:attribute><xsl:attribute name="rel">external</xsl:attribute>
<xsl:value-of select="title" disable-output-escaping="yes"/>
</xsl:element>
that could be replaced by the much more readable
<a href="http://events.stanford.edu/e/e/?d={replace(detailpath,'/events/','')}"
id="{@eventID}" rel="external">
<xsl:value-of select="title"/>
</a>
Generally, some refactoring is long overdue for this code.
