Count occurence and add the index in xsl

Hello all,

i want to get the index in the output.

Input XML looks like the
following
----------------------------------------------------
<?xml
version="1.0" encoding="UTF-8"?>
<Zeitraum>
    <Years
format="yyyy">2005</Years>
    <Days>21</Days>
    <Weeks>22</Weeks>
<Date>
        <Day>10</Day>
        <Month>02</Month>
<Year>2006</Year>
    </Date>
    <test> </test>
    <test></test>
    <Date>
<Day>10</Day>
        <Month>02</Month>
        <Year>2006</Year>
    </Date>
<test></test>
</Zeitraum>

I have the following xsl
---------------------------------

    <xsl:output method="xml" indent="yes"/>
<xsl:template match="/*">
        <tree id="0">
            <xsl:call-template
name="TreeXML">
                <xsl:with-param name="nameTmp"
select="name()"/>
            </xsl:call-template>
        </tree>
</xsl:template>
    <xsl:template name="TreeXML">
        <xsl:param
name="nameTmp"/>
        <item id="{$nameTmp}" text="{name()}">
<xsl:for-each select="*">
                <xsl:call-template name="TreeXML">
<xsl:with-param name="nameTmp" select="concat($nameTmp,'_',name())"/>
</xsl:call-template>
            </xsl:for-each>
        </item>
</xsl:template>
</xsl:stylesheet>

I got the following output
------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<tree id="0"><item id="Zeitraum" text="Zeitraum"><item id="Zeitraum_Years"
text="Years"/>
      <item id="Zeitraum_Days" text="Days"/>
      <item
id="Zeitraum_Weeks" text="Weeks"/>
      <item id="Zeitraum_Date"
text="Date"><item id="Zeitraum_Date_Day" text="Day"/>
         <item
id="Zeitraum_Date_Month" text="Month"/>
         <item id="Zeitraum_Date_Year"
text="Year"/>
      </item>
      <item id="Zeitraum_test" text="test"/>
<item id="Zeitraum_test" text="test"/>
      <item id="Zeitraum_Date"
text="Date"><item id="Zeitraum_Date_Day" text="Day"/>
         <item
id="Zeitraum_Date_Month" text="Month"/>
         <item id="Zeitraum_Date_Year"
text="Year"/>
      </item>
      <item id="Zeitraum_test" text="test"/>
</item>
</tree>

My Expected output is
-----------------------------------------
<?xml version="1.0"
encoding="utf-8"?>
<tree id="0">
    <item id="Zeitraum" text="Zeitraum">
<item id="Zeitraum_Years" text="Years"/>
        <item id="Zeitraum_Days"
text="Days"/>
        <item id="Zeitraum_Weeks" text="Weeks"/>
        <item
id="Zeitraum_Date_0" text="Date">
            <item id="Zeitraum_Date_0_Day"
text="Day"/>
            <item id="Zeitraum_Date_0_Month" text="Month"/>
<item id="Zeitraum_Date_0_Year" text="Year"/>
        </item>
        <item
id="Zeitraum_test_0" text="test"/>
        <item id="Zeitraum_test_1"
text="test"/>
        <item id="Zeitraum_Date_1" text="Date">
<item id="Zeitraum_Date_1_Day" text="Day"/>
            <item
id="Zeitraum_Date_1_Month" text="Month"/>
            <item
id="Zeitraum_Date_1_Year" text="Year"/>
        </item>
        <item
id="Zeitraum_test_2" text="test"/>
    </item>
</tree>
