Re: Selecting the first sentence of a paragraph

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:output omit-xml-declaration="yes"/>

  <xsl:template match="/">
    <xsl:apply-templates select="p" mode="fstSent"/>
  </xsl:template>

  <xsl:template match="@* | node()" mode="fstSent">
    <xsl:choose>
      <xsl:when test="not(self::p)
                     and
                      preceding::text()
                        [generate-id(ancestor::p[1])
                        =
                         generate-id(current()/ancestor::p[1])
                        ]
                        [contains(., '.')]"/>

      <xsl:when test="self::text()[contains(., '.')]">
        <xsl:value-of
        select="concat(substring-before(., '.'), '.')"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:copy>
          <xsl:apply-templates select="@* | node()"
                               mode="fstSent"/>
        </xsl:copy>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

</xsl:stylesheet>

when applied on this source xml (a complicated variant of the one originally
provided):

<p> Identical
  <u>and similar</u>
  <b>
    <i>to</i>
    <keyword>systat</keyword>.
   The optional argument
  </b>
  <arg> n</arg> specifies the level of detail.
</p>

produces the wanted result:

<p> Identical
  <u>and similar</u>
  <b>
    <i>to</i>
    <keyword>systat</keyword>.</b></p>
