Htmlpurifier: Auto Br

How i can get:

firstp

second p

from:

first p

second p

using HTMLPurifier?

Solution 1:

I'm not sure about the specifics, but since this question has no answers, see if these pointers help you:

If you're really set on solving this with HTML Purifier, you might be able to write a textnode transformation that does an nl2br or str_replace by writing a class that extends HTMLPurifier_AttrDef_Text. Pseudocode:

classHTMLPurifier_AttrDef_Text_LinebreaksextendsHTMLPurifier_AttrDef_Text{
    publicfunctionvalidate($string, $config, $context) {
        $string = parent::validate($string, $config, $context);
        return str_replace("\n", "<br />", $string);
    }
}

Then you'd inject your class into HTML Purifier:

$purifier->set('HTML.DefinitionID', 'aNameForYourDefinition');
$purifier->set('HTML.DefinitionRev', 1);
//$purifier->set('Cache.DefinitionImpl', null);$htmlDef = $purifier->config->getHTMLDefinition();
$htmlDef->manager->attrTypes->set(
     'Text',
     new HTMLPurifier_AttrDef_Text_Linebreaks()
);

Caveats:

  1. The Text AttrDef may be htmlspecialchars()-ed (it'd be sane, really). Then you're out of luck with that approach. You'd have to find a way to inject a <br /> node, instead.
  2. That might be too late in the process to give you the control you want - that changes the text nodes 'template' (so to speak), but the actual HTML definition might already happily be making use of a HTMLPurifier_AttrDef_Text instance.

See if that helps you at all?

There's also a thread on the HTML Purifier forum (did you start it? I wouldn't be surprised) - nl2br, auto <br /> insertion. If you find a solution, you could post your answer there.
