Re: [xsl] preceding-sibling in a group

Martin's suggestions would both work. Another idea would be 

<xsl:variable name="first-note" 
select="current-group/PART_DES[matches(.,'NOTE')][1]


<xsl:for-each select="current-group()">
                <xsl:choose>
                    <xsl:when test=". is $first-note or . >> $first-note">
                        <note>

...

Here is what I am getting:
 
<?xml version="1.0" encoding="UTF-8"?>
<root>
   <entry>
      <figure>99999</figure>
      <description>DIPSTICK</description>
      <description>O-RING</description>
      <description>SCREW, SELF-TAPPING</description>
      <note>NOTE: (1) NOT SERVICED SEPARATELY. INCLUDED IN</note>
      <note>58F-98-40740 SEAL KIT.</note>
   </entry>
   <entry>
      <figure>69500</figure>
      <note>DIPSTICK</note>
      <note>O-RING</note>
      <note>SCREW, SELF-TAPPING</note>
   </entry>
</root>
 
The idea is that when I see a “NOTE” string, I want that entry and all 
following within the same group to be <note> elements. So I am look for 
preceding-sibling or self that contains “NOTE” but restricted to the same 
group. I am using XSLT 3. Thank you very much.
