Need Help??

Wonko the sane has asked for the wisdom of the Perl Monks concerning the following question:

I am looking for an easy way to convert HTML entities, like

&acute;
&nbsp;
&amp;
[download]

into thier numeric representations.

So.
& would be converted to &
¡ would be converted to ¡

and so on.

I need this to work for ALL of the HTML entities. I am trying to get out of writting
a search and replace regex for all 255 of the different HTML entities like this. :)

I find it hard to believe that there is not a module already out ther that can do this for me.

Any help or pointer on solving this problem would be much appreciated.

Best Regards,
Wonko

See HTML::Entities. It has a function named `encode_entities_numeric()` which does what you're looking for. Cheers, Ovid New address of my CGI Course.	[reply]

Browsing the source of HTML::Encoder, I find a table that provides the reverse mapping of what you're looking for -- sort of. It could be helpful. Update: Hold the phone! I found it: HTML::Entities::Numbered provides conversions between numbered and named entities. Caution: Contents may have been coded under pressure.	[reply]
