Here are some examples:

if you need to remove all html tags:

${esc.h}set(${esc.d}mystring = "<span>test span</span><p> test p</p>")

${esc.d}mystring.replaceAll("</?[^>]+/?>", "");

to remove, for example, only p tags

${esc.h}set(${esc.d}mystring = "<span>test span</span><p> test p</p>")

${esc.d}mystring.replaceAll("</?p[^>]*/?>", "");
