[xsl] Problem for : increment a variable in a for-each?

[que Li <queincanada@xxxxxxxx>]

Hi:

I found several people asked the same question with me
"Re: [xsl] how to increment a variable in a for-each
loop" but it really didn't resolve my problems. So
just wonder could I get help ? I spent lots of time on
it and can't get solution!

My xml file
<root> 
<list>
    <ID>21</ID>
   <Title>text1</Title>
   <ParentID>1<ParentID>
</list>
<list>
    <ID>22</ID>
   <Title>text2</Title>
   <ParentID>21<ParentID>
</list>

<list>
    <ID>23</ID>
   <Title>text3</Title>
   <ParentID>21<ParentID>
</list>    

<list>
    <ID>24</ID>
   <Title>text4</Title>
   <ParentID>21<ParentID>
</list>  

<list>
    <ID>25</ID>
   <Title>text5</Title>
   <ParentID>1<ParentID>
</list>  

</root>

What I want do: I need do different thing  for the 
node which  parentID is 21(by passing in )(exampel:If
it is first child then I need bold. if not first and
not last one then I need do second thing. If the node
is last child then I need do third things.

I try to use the call:template and xsl:for each to
pass the parameter but the count is always set to
initial since I run so many for each 
what I shoud do ?

My code


<xsl:template match="root">

<xsl:for each select="list">

<xsl:if test="parented =1">

<xsl:call-template name= !0findChildNode!1>

  <xsl:with-param name=!1ID!1 select="ID!1/>

</xsl:call-template>

</xsl:for-each>

</xsl:template>



<xsl:template name="findChildNode!1>

<xsl:param name="ID!1>

<xsl:param name="count!1 select="0!1/>

<xsl:for-each select="../list!1>

   <xsl:if test="parentID=$ID!1>

    <xsl:call-template  name="formatChild!1>

<xsl:with-param name="count" select="$count+1!1/>

   </xsl:if>

</xsl:for each>

</xsl:template>



<xsl:template name="formatChid!1>

   <xsl:param name="count!1>

<xsl:variable name="TotalChildCount!1 select=!1?!1/>
(Note: I don't know how I can get all child node count
based on the one parentID)

            <xsl:choose>

<xsl:when  test="$count=1!1>do firsth thing</xsl:when>
<xsl:when  test="$count &gt; 1 and $count &lt; 
$TotalChildCount!1>do second  thing</xsl:when>

<xsl:when  test="$count=$TotalCount!1>do third 
thing</xsl:when>

          </xsl:choose>

</xsl:template>



Question: 

 1.   Why every time the $count is 0 and never
incresement  ?
2.   How I can get the total child count value based
on the parent ID?

Thanks for any help
Helena
