Suppressing text content is commonly done in the past with a show string yank and possible need for <?tpignme=1> amongst other needs.

A alternative way is to use the <?attr> PI to tell 3B2 to move the current formatting position to the end of the current paragraph.

You would of course need to know the characters position of the end of the current paragraph.

This example below (in old-style PI code) is applicable for any XML document:

<hidden>HIDE ME</hidden>

Inside the tag ‘hidden’:

<?show “^currentNodeEndPos”$^[xpath x3b2:end-pos(.)]>
<^?attr 4,0,^currentNodeEndPos>
