Hi Andy,

I wish it were so simple... the priority of the elements != the document order of the elements. If there's no monogr/author, then it jumps to analytic/author (which is before it in document order), then editor (somewhere else), and so on.

I'm using 2.0 (sorry, I should've mentioned that), so I'll try Michael's solution and let you know how it goes...

<xsl:sort select="
monogr/author |
self::*[not(monogr/author)]/analytic/author |
self::*[not(monogr/author | analytic/author)]/monogr/editor |
self::*[not(monogr/author | analytic/author |
monogr/editor)]/monogr/title"/>
I think for XSLT 1.0 you can simplify that select to:

<xsl:sort select="(monogr/author|analytic/author)[1]"/>

I don't think so. That will select the first in document order, not the
first in the order of precedence defined in the requirement statement.

Maybe I misunderstood the requirements, but I thought it said that under the biblStruct element you wanted the first one that occurred to be sorted. So given:

<?xml version="1.0" ?>
<document>
  <biblStruct>
    <analytic>
      <author>Author Name 2</author>
      <title>Article Name 2</title>
    </analytic>
    <monogr>
      <author>Author Name 0</author>
      <title>Journal Title 0</title>
      <editor>Editor Name 0</editor>
    </monogr>
  </biblStruct>
  <biblStruct>
    <monogr>
      <author>Author Name 1</author>
      <title>Journal Title 1</title>
      <editor>Editor Name 1</editor>
    </monogr>
  </biblStruct>
</document>

and:

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output method="xml" encoding="UTF-8" indent="yes"/>
  <xsl:template match="biblStruct">
    <xsl:copy-of select="."/>
  </xsl:template>
  <xsl:template match="document">
    <xsl:copy>
      <xsl:apply-templates select="biblStruct">
        <xsl:sort order="ascending" data-type="text" select="(monogr/author|analytic/author)[1]"/>
      </xsl:apply-templates>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="/">
    <xsl:apply-templates select="*[1]/self::document"/>
  </xsl:template>
</xsl:transform>

it should result in:

<?xml version="1.0" encoding="UTF-8"?>
<document>
   <biblStruct>
      <monogr>
         <author>Author Name 1</author>
         <title>Journal Title 1</title>
         <editor>Editor Name 1</editor>
      </monogr>
  </biblStruct>
   <biblStruct>
      <analytic>
         <author>Author Name 2</author>
         <title>Article Name 2</title>
      </analytic>
      <monogr>
         <author>Author Name 0</author>
         <title>Journal Title 0</title>
         <editor>Editor Name 0</editor>
      </monogr>
  </biblStruct>
</document>

So what did I misunderstand about the problem?
