RE: [xsl] preceding/following character?

["Michael Kay" <mike@xxxxxxxxxxxx>]

One solution to this kind of problem is to replace the markup by text, and
then treat it as an analyze-string problem:

<xsl:template match="bar">
  <xsl:text>%bar%</xsl:text>
</xsl:template>

<xsl:template match="foo">
  <foo_out>
    <xsl:variable name="temp" as="xs:string">
      <xsl:value-of>
         <xsl:apply-templates/>
      </xsl:value-of>
    </xsl:variable>
    <xsl:analyze-string select="$temp" regex="%bar%\.">
      <xsl:matching-substring>
        <xsl:text>. </xsl:text>
        <bar_out/>
      </
    </
  </
</

An alternative approach is to treat it as a positional grouping problem:

<xsl:for-each-group select="node()" 
  group-starting-with="bar[starts-with(following-sibling::node()[1], '.')]">
  <xsl:text>. </xsl:text>
  <bar_out/>
  <xsl:value-of select="substring-after(current-group()[2], '.')"/>
  <xsl:copy-of select="current-group()[position() gt 2]"/>
</xsl:for-each-group>
