[xsl] if child element does not exist stop generation

["Mikael Petterson \(KI/EAB\)" <mikael.petterson@xxxxxxxxxxxx>]

Hi,

I have the following line in my xml:
=========================
.....
<attribute name="reserved">
   <description>
     Reference to other product
   </description>
   <readOnly/>
   <dataType>
     <sequence>
       <moRef name="Object"/>
       <length>5</length>
       <nonUnique/>
      </sequence>
    </dataType>
 </attribute>

I need to check if there is a <length>-element as child to <sequence>
otherwise I need to terminate my code generation.

All hints are very much appreciated.

Cheers,

//Mikael

This is my xsl:

 <xsl:when test="sequence">
     <xsl: if test="not(name(./*)='length')">
      <xsl:message terminate="yes">
        <!-- class name and attribute error message -->
         Attribute:<xsl:value-of select="../@name"/>
         Error:sequence missing <length> child!
       </xsl:message>
      </xsl:if>
  </xsl:when>

I get the following error message:

[java] [Fatal Error] interface.xsl:477:11: Element or attribute do not match
