( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Okay, I have some web forms that some of my Dutch customers use. My problem is that they occasionally use high bit characters like ë ï é and í. When I redisplay those pages, the system craps out with control characters A<<x0.

So I think, "Aha! I'll use a module to escape those pesky characters into HTML". So I use HTML::Entities decode on my text field inputs.

My problem is that HTML::Entities also escapes HTML characters that I WANT my text entry people to be able to use. I want them to be able to use <p> and <br> to have some basic formatting control.

HTML::Entities allows you to force only some characters to be encoded and to leave others alone. But there's no easy way to complement that list. In other words, there's no function for 'export everything BUT <> in the incoming string'.

I'm hoping you might be able to save me from creating a whole manual lookup table :)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
