[xsl] How do I process a result-tree fragment?

["Greg Bender" <greg at thisoldtractor dot com>]

Currently I am using the following procedure (acquired from
http://www.jenitennison.com) to escape apostrophe characters (I need to do
this in order to place the resulting information in javascript):

<xsl:template name="escape-apos">
   <xsl:param name="string" />
   <!-- create an $apos variable to make it easier to refer to -->
   <xsl:variable name="apos" select='"&apos;"' />
   <xsl:choose>
      <!-- if the string contains an apostrophe... -->
      <xsl:when test='contains($string, $apos)'>
         <!-- ... give the value before the apostrophe... -->
         <xsl:value-of select="substring-before($string, $apos)" />
         <!-- ... the escaped apostrophe ... -->
         <xsl:text>\'</xsl:text>
         <!-- ... and the result of applying the template to the string
after the apostrophe -->
         <xsl:call-template name="escape-apos">
            <xsl:with-param name="string" select="substring-after($string,
$apos)" />
         </xsl:call-template>
      </xsl:when>
      <!-- otherwise... -->
      <xsl:otherwise>
         <!-- ... just give the value of the string -->
         <xsl:value-of select="$string" />
      </xsl:otherwise>
   </xsl:choose>
</xsl:template>


This method works great when I pass it a string. However, when I pass it a
result-tree fragment, I loose the mark-up language. For example:

If I pass "<div><b>these word's are bold.</b></div>"

I get "These word\'s are bold."

When what I want is "<div><b>these word\'s are bold.</b></div>"


I've tried replacing the 'xsl:value-of' commands with 'xsl:copy-of'
commands. This solution works if the result-tree fragment doesn't contain
any apostrophes (it just passes the variable through). However, when the
result-tree fragment contains apostrophes, I loose the result-tree fragment.

I think the contains(), substring-before(), and/or substring-after()
statements are converting the result-tree fragment to a string.

Any help is appreciated.
