Re: Using HTML tags

encode the previous string as

<description>Some &lt;b&gt;description&lt;/b&gt;</description>

why couldn't that be encoded with elements

encode the previous string as

<description>Some <b>description</b></description>

in which case you would be in much better position.

<fp:if-post>
  <fp:write to="XMLdoc" select="{@tag}">
    <request:get-parameter name="{@tag}"/>
  </fp:write>
</fp:if-post>

<fp:if-post>
  <fp:write to="XMLdoc" select="{@tag}">
    Some <b>description</b>
  </fp:write>
</fp:if-post>
