[erlang-questions] beginner: Generating HTML with ">" from Erlang

[Bengt Kleberg]

Could I use an xmerl hook function to preserve  ">" in the text of a
specific tag (say 'script')?

Ex (this will obviously not work, but perhaps someone has needed to
short circuit xmerl some time before and know what would work):

script( _Data, _Attributes, _Parent, E ) -> E.
