RE: Problem for : increment a variable in a for-each?

 Thanks lots for help.

Now I try to use the template except using the
<xsl:for-each-->

But I still can't figure out how I can format the
child node since I can't get how many child node.
example for the ID=21 ,It has three child (which ID
are 22,23,24). sorry that I am so poor skill for xsl
language.

What I need do:
Format the parent node title (Which parentID is 1 and
ID is 21) then
find all child ID which parent_ID is 21 then format
the child ID based on there position.If the first
child
then I need do format 1,if the last child then I do
format 2,If not first and last one then I format3

My code:
 <xsl:template match="Lists"> 
    <xsl:apply-templates/>
 </xsl:template>

 <xsl:template match="List" >
    <xsl:choose>
       <xsl:when test="Parent_ID = 1">
         <!--parent Node-->
        <xsl:variable name="ID" select="Subject_ID"/>
        <xsl:choose>
        <xsl:when test="position()=1">
         <b><xsl:value-of select="Title"/></b>
        </xsl:when>
        <xsl:when test="position() = last()">
        <b> and <xsl:value-of select="Title"/></b>
        </xsl:when>
        <xsl:when test="position() &gt;1 and position()
&lt;last() ">
        <b>; <xsl:value-of select="Title"/></b>
      </xsl:when>
        </xsl:choose>   
        <!--need find child node and format child node
title-->
<!--??? How I can get know how many child node for
this current node-->
       <xsl:for-each select="../List">
          <xsl:choose>
          <xsl:when test="Parent_ID=$ID">
           <b><xsl:value-of select="Title"/></b>      
                                       </xsl:when>
</xsl:choose>

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 ?


Try the following stylesheet, hopefully it's clear
enough.  A good rule
of thumb - always use templates!  If you are new to
the language, using
xsl:for-each will tempt you into the wrong way of
thinking, whereas
using templates forces you to understand whats going
on in the
background (although it seems completely wrong to
start with :)

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:param name="ID" select="'21'"/>

<xsl:template match="/">
      <xsl:apply-templates/>
</xsl:template>

<xsl:template match="list">
      <xsl:choose>
              <xsl:when test="ID = $ID and
not(preceding-sibling::list)">
                      <!-- I'm equal to 21 and at the start of the
list -->
              </xsl:when>
          <xsl:when test="ID = $ID and
not(following-sibling::list)">
                      <!-- I'm equal to 21 and at the end of the list
-->
          </xsl:when>
          <xsl:when test="ID = $ID">
                      <!-- I'm equal to 21 and in the middle of the
list -->
          </xsl:when>
          <xsl:otherwise>
                      <!-- I'm not equal to 21! -->
          </xsl:otherwise>
      </xsl:choose>
</xsl:template>

</xsl:stylesheet>
