Re:  Predicates question
You have a couple of other syntax errors, too.  You forgot to close
your "<xsl:value-of..." elements with "/>".  Try this:

<?xml version="1.0" encoding="UTF-8"?><xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">B  <xsl:output
method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">B  B  <xsl:apply-templates
select="/bookstore/book[position()&lt;3]" />B  </xsl:template>
<xsl:template match="bookstore/book">B  B  <h1><xsl:value-of
select="title"/></h1>B  B  B  <xsl:value-of select="price"/>
</xsl:template>B B </xsl:stylesheet>
