<h2>SAFEHTML Testing interface</h2>
This parser strip down all potentially dangerous content within HTML:
<ul>
<li> opening tag without its closing tag
<li> closing tag without its opening tag
<li> any of these tags: "base", "basefont", "head", "html", "body", "applet", "object", "iframe", "frame", "frameset", "script", "layer", "ilayer", "embed", "bgsound", "link", "meta", "style", "title", "blink", "xml" etc.
<li> any of these attributes: on*, data*, dynsrc
<li> javascript:/vbscript:/about: etc. protocols
<li> expression/behavior etc. in styles
<li> any other active content
</ul>
<p>If you found any bugs in this parser, please inform me — ICQ:551593 or <a href=mailto:thingol@mail.ru>thingol@mail.ru</a> - Roman Ivanov.
