Thanks Andrew,

I understand the logic, just a practical question.
I wrote the application with the javax.xml.transform. Is there a similar
function as saxon:parse() which I can use with my excising code or and
easy way to sue it without having to rewrite and retest the whole
application?

An other small side problem is that the transformation crashes with a
variable in the apply-templates (??). I tried as I hoped that that would
do the job, but it crashes.

		      		<xsl:variable name="htmlContent" select="."/>		      		
	            	<!-- <xsl:call-template name="replace">
        				<xsl:with-param name="string" select="$htmlContent"/>
    				</xsl:call-template> -->
					<xsl:value-of select="$htmlContent"/>
	           	</fo:block>
           	</xsl:if>
  </xsl:template>
 
  <xsl:template name="replace"> 
    <xsl:param name="string"/>
    <xsl:value-of disable-output-escaping="yes" select="$string"/>
  </xsl:template>
