RE: what index is the current item in a list?

In XSLT 2.0:

<xsl:number select="parent::Item" count="*[Type='type2']"/>

In 1.0:

<xsl:for-each select="parent::Item">
  <xsl:number count="*[Type='type2']"/>
</xsl:for-each>

Or if you prefer:

count(parent::Item/preceding-sibling::*[Type='type2'])

Subject: [xsl] what index is the current item in a list?

I want to do something that seems like it should be easy, but I cannot
figure it out.

I have a list of items like this in the input XML:

<Item>
   <Type>type1</Type>
   .. Other elements here..
</Item>
<Item>
   <Type>type2</Type>
   .. Other elements here..
</Item>
<Item>
   <Type>type1</Type>
   .. Other elements here..
</Item>
<Item>
   <Type>type3</Type>
   .. Other elements here..
</Item>
<Item>
   <Type>type2</Type>
   .. Other elements here..
</Item>

Each "Type" is handled differently, so the templates look like this:

<xsl:template match="*[Type = 'type1']">
      .. Do type1 stuff here..
</xsl:template>

<xsl:template match="*[Type = 'type2']">
      .. Do type2 stuff here..
</xsl:template>

<xsl:template match="*[Type = 'type3']">
      .. Do type3 stuff here..
</xsl:template>

Now, further down in the input XML is another list of items 
related to,
say, type2 Items, in the same order as in the Item list, like this:

<Type2Info>
    .. Elements related to the first type2 item is here..
</Type2Info>
<Type2Info>
    .. Elements related to the second type2 item is here..
</Type2Info>

So, I'm inside the second match template above and I want to 
get at the
proper Type2Info element. Logically, what I want to do is this:  "Get
the Nth Type2Info node where N is the ordinal number of the type2 Item
within the list of type2 Items."

I can make a list of just the type2 Items, that's easy. And I 
can access
the Nth Type2Info item, that's easy. I can even find the current type2
Item within the list of type2 Items, but I can't see how to determine
what N is. I've studied position() and xml:number and 
count(), etc. but
nothing seems quite what I need.

Help!

Thanks,

Lee
