Re^2: HTML::Entities - encode all non-alphanumeric and foreign chars?

Hadn't imagined it would take regex elements...

The first two

$encoded = encode_entities($input, '\W');
$encoded = encode_entities($input, '^\w');
[download]

wouldn't work for me. But I tried

$encoded = encode_entities($input, '\\W'); # note double backslash
[download]

and that did work, with one little picky issue - it was encoding every whiteepsace char as well whic, while not technically bothersome, is just not needed.

So I tried the last formulation witha space added to list - had to add it as a simple typed space - wouldn't accept a \s:

$encoded = encode_entities($input, '^a-zA-Z0-9_ ');
[download]

and that does it perfectly.

Thanks.

`$encoded = encode_entities($input, '\\W'); # note double backslash` [download] Single backslash works for me. Sure you weren't trying with a double-quoted string? (`'\w', '\\w', "\\w"` should all be the same string, `\w` — whereas `"\w"` is just `w`.) Oh, and the same goes for `\s`. It should Just Work in a single-quoted string, but in a double-quoted string, you'll need to double the backslash. `print "Just another Perl ${\(trickster and hacker)},"` The Sidhekin proves Sidhe did it!

Yes, absolutely right - double quotes. Replacing with single quotes makes '\W' work like a charm. Thanks. But, just to be finicky and difficult, '\W\s' is still converting spaces to `&#32.` UPDATE: Ya, of course it was. This is the list of UNSAFE characters to be encoded. So if I include '\W\s', that specificlaly tells it to encode spaces. What I want is '^\w\s' - anything that's not a word char or a space. Works perfect now. UPDATE 2 OK, now this is very cool. With this formulation, I can create a very well defined list of what is and is not to be encoded. For example (what I'm using): `$encoded = encode_entities($input'^\w\s.\-');` [download] encodes everything that is NOT a word char, or a space, or a period, or a dash (backslash needed to escape 'cause the dash is part of the module's syntax)	[reply] [d/l] [select]
