RE: hard xsl problem

Handling implicit structure is always easier in XSLT 2.0, though this one is
still a little tricky.

I would do a first pass in which all the "(" characters (and preceding
whitespace) are replaced by <lpar/> and all the ")" (and following
whitespace) are replaced by <rpar/>. This is easily done in 2.0 using
xsl:analyze-string.

<xsl:template match="text()">
  <xsl:analyze-string select="." regex="(\s*\()|(\)\s*)">
    <xsl:matching-substring>
      <xsl:choose>
        <xsl:when test="contains(.,'(')><lpar/></xsl:when>
        <xsl:otherwise><rpar/></xsl:otherwise>
      </
    </
  </
</
      

Then in a second pass, use:

<xsl:for-each-group group-starting-with="lpar|rpar">
  <xsl:if test="self::rpar">
    <xsl:copy-of select="current-group() except ."/>
  </
</

Not tested.
