Hi people.
I have a problem with an algorithm that I don't know how to realize in XSLT.
I need to show in HTLM the <description> elements of all groups but only if
between an item/type="T" element and another item/type="T" element are
existing item/type="P" elements. In this way, only the SECOND GROUP
<description> elements should be processed. The problem is that I can know
that nobody <type>P</type> elements are present only after process the group
(between <type>T</type> elements) and it's too late.
Who can help me for this URGENT problem?
Thanks in advance.

<!-- FIRST GROUP -->
<item>
<type>T</type>
<description>title 1</description>
</item>
<item>
<type>S</type>
<description>summary 1</description>
</item>
<!-- SECOND GROUP -->
<item>
<type>T</type>
<description>title 2</description>
</item>
<item>
<type>P</type>
<description>position 1</description>
</item>
<item>
<type>S</type>
<description>summary 3</description>
</item>
<!-- THIRD GROUP -->
<item>
<type>T</type>
<description>title 3</description>
</item>
