The stylesheet I provided worked only with strings, it doesn't have any
node, just text that looks like markup, there for you can not do
xalan:nodeset($str), it will be the same as doing
xalan:nodeset("<sometag>opps</sometag>"). It won't work. What you need to do
is to apply those templates inside the definition of a variable and use the
xalan:nodeset() on that variable.

Something like:
<xsl:variable name="mymarkup">
  <xsl:call-template name="unescape">
    <xsl:with-param name="str" select="value"/>
  </xsl:call-template>
</xsl:variable>

 <xsl:for-each select="xalan:nodeset($mymarkup)">
Or
 <xsl:apply-templates select="xalan:nodeset($mymarkup)"/>

You have to be sure that the string you pass to it is a well-formed xml text
representation

Hope this help
