RE: [xslt] xslt problem

That seems to be a rule you can translate directly into XSLT:

<xsl:template match="interestingNode[con='someString']">
  <xsl:copy>
    <xsl:copy-of select="con"/>
    <follow><return>0</return></follow>
    <xsl:copy-of select="space"/>
  </xsl:copy>
  <xsl:variable name="space" select="space"/>
  <xsl:for-each select="follow/*">
    <xsl:copy>
      <xsl:attribute name="space" select="$space"/>
      <xsl:copy-of select="child::node()"/>
    </xsl:copy>
  </xsl:for-each>
</xsl:template>
