Hi Anthony,
unfortunately the sample above is a simple extract of the hole project
already!
I need the countercariable wich takes values shown above during the
xml-terminal-part file Transformation!
The difficulty in in all is, the order of output elemets is not the
same like the order of elements in xml-source-tree. Therefore many
elements must be stored and concatet with other later elements. After
too days struggle to do it with xsl:variables I have desided yesterday
do built in a javascript. I have read in this newsgroup, that
xsl-experts don't like such stuff, but for my as newbie is no
alternativ at the moment. It works fine now, thanks for your help and
patieance.

here is the xsl:counter variable and the script:

<xsl:variable name="ek_counter">
     <xsl:choose>
          <!-- EK-Terminal found
         <xsl:when
test='string-length(substring-before(substring-after(string(Comment),"$EK:"),"$"))!=0'>
             <xsl:value-of select="myFun:sortTerminals(2)" />
         </xsl:when
         <xsl:otherwise>
             <xsl:value-of select= "myFun:sortTerminals(3)" />
        </xsl:otherwise>
   </xsl:choose>
</xsl:variable>

<msxsl:script language="javascript" implements-prefix="myFun">

var counter=0;
function sortTerminals(action)
{
	switch (action)
	{
		case 1:
		{
			counter=0;     // Reset
			break;
		}

		case 2:
		{
			counter=1;    // start new count
			break;
		}

		case 3:
		{
			counter++ ;   // count
			break;
		}
	}	//switch

	return (counter);
} 
 </msxsl:script>

</xsl:stylesheet>
