Ah, preceding-sibling was the trick. Thanks much!
Btw, I don't see how your first solution under 1.0 works - seems like it
would count the total number of type2 Items, not the "index" of this
particular type2 Item.

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
