Re: [xsl] call-template with dynamic parameters

Hello Saied,

I don't understand exactly, what you want to reach, but let me explain 
some things.

<xsl:variable name="path" 
select="/Kartenauftrag/Kundendaten/Privatkunde/Title">
  <xsl:choose>
    <xsl:when test="$path">
      ...
    </xsl:when>
    <xsl:otherwise>
      ...
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>

You can not assign a value to the variable via select and via the 
"content" of <xsl:variable>content</xsl:variable>. You have to choose 
one. If you have the first one with select, a node set is stored in the 
variable (or a string), otherwise a result tree fragment (RTF).

Maybe you want the following:

<xsl:variable name="path" select=".. same as above .."/>

<xsl:call-template name="table-cell">
  <xsl:with-param name="no_cell" select="15"/>
  <xsl:with-param name="word" select="$path"/>
</xsl:call-template>

If $path is empty because there are no 
/Kartenauftrag/Kundendatan/Privatkunde/Titel elements, an empty node set 
is passed to the next template "table-cell". You called the param $word, 
so I assume you don't want to have a node set but a string. You can 
reach this by using string() either at

<xsl:variable name="path" select="string(.. same as above ..)"/>

or at

<xsl:with-param name="word" select="string($path)"/>

In the template "table-cell" there must be a <xsl:param name="word"/>, 
otherwise you can't access the passed param value. If you add a select, 
you can give word a default value, e.g. select="''" as empty string or a 
special one.

Now is the question what you want to do exactly.

Regards,

Joerg
