You don’t need to copy xmerl_xml.

Simply write the following module.

====================================
-module(szoboszlay_xml).
-export([‘#text#’/1, ‘#xml-inheritance#’]).

‘#xml-inheritance#’() -> [xmerl_xml].

'#text#'(Text) -> ["<![PCDATA[", xmerl_lib:export_text(Text), "]]>”].
====================================

And you’re done. ;-)

BR,
Ulf
