XSLT - how to un-entitize WYSIWYG field values

Using XSLT presentation templates - no Perl (sigh)[/indent]
Scenario[indent]I have a DCT with a WYSIWYG textarea (in this case, using TinyMCE) - so the DCR will get some HTML tags embedded within it but encoded (e.g.:

<

will be stored as

&amp;lt;

) - If I just use

<p><xsl:value-of select="xpath-string"/></p>

in my XSLT - I'll end up with something like:

yadda yadda yadda <a href="...">mumble</a>

in the generated HTML file which will then show up, literally as:

yadda yadda yadda <a href="...">mumble</a>

in the browser.

I tried following based on the information from the webcast by putting the following in my XSLT code (after putting the appropriate jar file into customer_src/lib and running make_toolkit.ipl)

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xalan="http://xml.apache.org/xalan"
                xmlns:js="http://www.w3.org/javascript"
                extension-element-prefixes="js"
                exclude-result-prefixes="xalan"
                >
  <xalan:component prefix="js">
    <xalan:script lang="javascript"><![CDATA[
function wysiwyg(str) {
   var newstr = str.replace(/\&amp;lt;/g, "<");
   newstr = newstr.replace(/\&amp;gt;/g, ">");
   return newstr;
}
]]></xalan:script>
  </xalan:component>
  <xslutput method="xml" indent="yes"
              doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
              doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"/>
  <xsl:template match="/">
...
          <p><xsl:value-of select="js:wysiwyg({xpath-string})"/></p>
...

But this results in a java.lang.StackOverflowError - if I put the argument within single-quotes like:

...
          <p><xsl:value-of select="js:wysiwyg('{xpath-string}')"/></p>
...

I don't get the error - but I also get no output.

Has anyone here already resolved this issue? If so - could you share how?

It turned out to be much simpler than what I was trying.
DCR input:[indent]

<advisory>
...
<travel_tips>yadda yadda at &lt;strong&gt;****.com&lt;/strong&gt; or to use yadda yadda.&lt;br /&gt;&lt;br /&gt;Additionally, yadda yadda:&lt;br /&gt;&lt;ul&gt;&lt;li&gt;mumble.&lt;/li&gt;&lt;li&gt;mumble &lt;a title="TSA carryon baggage procedures" href="http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm" target="_blank"&gt;TSA carryon baggage procedures&lt;/a&gt;.&lt;/li&gt;&lt;li&gt;mumble.&lt;/li&gt;&lt;li&gt;mumble.&lt;/li&gt;&lt;/ul&gt;</travel_tips>
</advisory>

[/indent]XSLT:[indent]

...
<p><xsl:value-of disable-output-escaping="yes" select="/advisory/travel_tips"/></p>

[/indent]Results in:[indent]yadda yadda at ****.com or to use yadda yadda.

Additionally, yadda yadda:

• mumble.
• mumble TSA carryon baggage procedures.
• mumble.
• mumble.
