xpath find previous cousin node

I already use the following:: axis quite extensively.  Instead of giving
you my complicated script, I will try to describe it and give samples of
its most important xpath statements.

Given this XML structure:
   <document date="2001.06.03">
      <war title="a" complete="yes"> . . . </war>
      <legislation title="b" complete="yes"> . . . </legislation>
      <war title="c" complete="no"> . . . </war>
   <document date="2001.06.10">
      <civil-event title="d" complete="yes">  . . . </civil-event>
   <document date="2001.06.17">
      <war title="c" complete="continued"> . . . </war>
      <exploration title="e" complete="yes"> . . . </exploration>

In the XSL, I first use <xsl:for-each select="//*[@complete]"> to find all
tags with the complete attribute (complete="yes" is the default, so this
for-each statement skips "yes" tags).  Then I create a variable called
$element that contains the name of the tag I am on.  Therefore, if I am on
<war title="c" complete="no">, then I can use <xsl:when test="following::
*[name()=$element][1][@complete='continued']"> and <xsl:when test="
@title=following::*[name()=$element][1]/@title]"> to make sure to make sure
the next <war> completes the previous one.  I have similar checks for when
@complete=continued, but it uses the preceding:: axis.

Looking at another XML sample, if it is like this:

   <document date="2001.06.03">
      <war title="c" complete="no"> . . . </war>
   <document date="2001.06.10">
      <civil-event title="d" complete="yes"> . . . </civil-event>
          <!-- civil-event interrupts the flow but war is continued in this
class -->
      <war title="c" complete="continued"> . . . </war>

Then I can find the interrupting <civil-event title="d"> by the xpath
statement "following::*[name()
=$element][1]/preceding-sibling::civil-event".  But if the <civil-event
title="d"> takes up the whole class (or, in other words is the only child
of <document>) as it does in the first XML sample, then this xpath
statement doesn't work.  It seems I can find everything but this situation.
This is what I need help with.

Thanks again,
