Hi, Eric,

Here is more of a "push" approach (assuming you are able to use XSLT
2.0+)--which I highly recommend whenever working with XSLT.


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs" version="2.0">

    <xsl:strip-space elements="*"/>
    <xsl:output method="text"/>

    <xsl:template match="/">
        <xsl:apply-templates select="session"/>
    </xsl:template>

    <xsl:template match="presentation">
        <xsl:apply-templates/>
    </xsl:template>

    <xsl:template match="person">
        <xsl:value-of select="."/>
        <xsl:text>&#09;</xsl:text>
        <xsl:sequence
            select="
                string-join(
                (distinct-values(for $a in following-sibling::affiliation
                return
                    $a)), '|'
                )
                "/>
        <xsl:text>&#09;</xsl:text>
        <xsl:sequence select="../paper"/>
        <xsl:if test="position() ne last()">
            <xsl:text>&#10;</xsl:text>
        </xsl:if>
    </xsl:template>

    <xsl:template match="affiliation"/>

    <xsl:template match="paper"/>

</xsl:stylesheet>
