Re:  What's wrong with a variable inside a xsl:when ?
Yeah I did that



<xsl:variable name="translation">
<xsl:choose>
<xsl:when test="$kind = 'ADJA'"><xsl:value-of select="mt:lexicon_adjectives($lemma)"/></xsl:when>
<xsl:when test="$kind = 'NN'"><xsl:value-of select="mt:lexicon_noun ($lemma)"/></xsl:when>
<xsl:otherwise>[set the value here]</xsl:otherwise>
</xsl:choose>
</xsl:variable>



and what I got from saxon was :


Warning: at xsl:variable on line 25 of file:/Users/jeckyll/studium/au/ project/norman/norman_neu.xsl:
SXWN9001: A variable with no following sibling instructions has no effect



but that sounds strange to me because i think i have sibling element in my variable element or am i wrong?


thanks for help!

I don't understand this, but probably your notion that you need to do this in the way you are trying to do it is wrong.


In general, with XSLT you need to set the value of a variable in a manner that seems "inside out" as compared to procedural languages.

This is the general form:

<xsl:variable name="x">
  <xsl:choose>
    <xsl:when test="">[set the value here]</xsl:when>
    <xsl:otherwise>[set the value here]</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

Hi Folks,

i have a problem with defining a variable inside a when element.

If i write it this way, so that the variable is outside everything is
fine with saxon.

   <xsl:function name="mt:check_the_next">
     <xsl:param name="kind"/>
     <xsl:param name="lemma"/>

     <xsl:variable name="translation_adja"
select="mt:lexicon_adjectives('texanisch')"/>

     <xsl:choose>
       <xsl:when test="$kind = 'ADJA'">
	.	
	.
	.

</xsl:function>

But if i write it this way,

   <xsl:function name="mt:check_the_next">
     <xsl:param name="kind"/>
     <xsl:param name="lemma"/>

     <xsl:choose>
       <xsl:when test="$kind = 'ADJA'">

          <xsl:variable name="translation_adja"
select="mt:lexicon_adjectives('texanisch')"/>
	.	
	.
	.

</xsl:function>


so that the variable is inside my when element saxon does nothing. It just tells me the following: Warning: at xsl:variable on line 22 of file:/Users/jeckyll/studium/au/ project/norman/norman_neu.xsl: SXWN9001: A variable with no following sibling instructions has no effect


I don't know what to o because the failure that there are no siblings is not correct i think because the value is choosen.

Pleas help me xsl-List members :) I need that variable inside my when
element so i can use a different function then inside another when
element.

What am i doing wrong ?


cheers,


norman
