Subject: [erlang-questions] Unescape HTML text
Print | Individual message | Show original | Report this message | Find messages by this author

Hi huis,

I want  to convert an HTML escaped text (http://www.w3schools.com/tags/ref_entities.asp) like this one:

bourg&eacute; Cop

to:

bourgé Cop

Is there any Erlang library for this?

Regards,
Zabrane

That's a subset of possible inputs, you're better off using a library
that's a bit more complete. This may be useful:
