I thought I share this one, just in case someone needs to call BaseX (xquery the database in this example) from xslt:

Example:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" exclude-result-prefixes="xsl basex"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xmlns:basex="java:org.basex.server.ClientSession">           
   
    <!-- create a new ClientSession object (only static methods can be called directly) -->   
    <xsl:variable name="session" select="basex:new('localhost', 1984, 'admin','admin')"/>
   
    <xsl:template match="/">
       
        <!-- putting the xquery in a variable makes it easier to work with quotes or xpath results from the input xml -->
        <xsl:variable name="query"><xsl:text>XQUERY for $doc in db:open(&quot;SampleDB&quot;) return $doc</xsl:text></xsl:variable> 
       
        <example>
            <!-- execute the query with a BaseX command -->
            <xsl:value-of select="basex:execute($session,string($query))"/>       
        </example>
       
    </xsl:template>
   
</xsl:stylesheet>
