Re: p:exec -- can it apply to only selected parts of input using a loop?

Here is my first viewport to convert the contents of chunk to xhtml

         <p:viewport match="//html/content/chunk">
             <p:unescape-markup>
               <p:with-option name="content-type" select="text/html"/>
             </p:unescape-markup>
            </p:viewport>
