[xsl] grouping duplicate links with xslt 1.0

[Terry Ofner <tdofner@xxxxxxxxx>]

I couldn't find any reference to this issue in the archive. If it has been
addressed before, please forgive.

I have an issue with MS Word outputting duplicate links in xml, breaking up
the text. I need to group identical links and output one link while leaving
all other nodes/text the same. Here is an example of the input xml:

<paragraphs>

    <!-- Have students practice [the activity in 9.01].-->
<p>Have students practice
    <internalLink>
    <target>Update_Link [7] [act_1]</target>the activity</internalLink>
    <internalLink>
    <target>Update_Link [7] [act_1]</target> in 9.01</internalLink>.</p>

    <!-- Have students practive [the activity in 9.02]. -->

<p>Have students practice <internalLink>
    <target>Update_Link [7] [act_2]</target>the activity</internalLink>
<internalLink>
    <target>Update_Link [7] [act_2]</target> in 9.02</internalLink>.</p>
</paragraphs>

I am limited to xslt 1.0. The following 1.0 sheet does everything I need it to
except it drops the final period.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">

    <!-- duplicate link processor -->

    <xsl:output method="xml" indent="yes"/>

<xsl:key name="link_target" match="internalLink" use="target" />


<xsl:template match="paragraphs">
    <xsl:for-each select="p">
    <p><xsl:apply-templates select="./text()[1]"/><internalLink>
	<target><xsl:apply-templates select="internalLink[count(. |
key('link_target', target)[1]) = 1]/target"/></target>
	<xsl:apply-templates
select="./internalLink/text()"/></internalLink></p></xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Here is the output using Oxygen/Saxon 6.5.5. Everything is good except for the
final period.

<?xml version="1.0" encoding="utf-8"?>
<p>Have students practice
    <internalLink>
      <target>Update_Link [7] [act_1]</target>
    the activity
     in 9.01</internalLink>
</p>
<p>Have students practice <internalLink>
      <target>Update_Link [7] [act_2]</target>
    the activity
     in 9.02</internalLink>
</p>

Any pointers would be most appreciated.
