<div class="help">Use with a Javascript- and cookie-enabled, relatively new version of a common browser. <em>Submitted input will also be HTML-rendered (XHTML 1) after htmLawed-filtering.</em>

<br /><br />For anti-XSS tests, try the <a href="http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/htmLawedSafeModeTest.php"><span class="notice">special test-page</span></a> or see <a href="http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/rsnake/RSnakeXSSTest.htm"><span class="notice">these results</span></a>.

<br /><br /><small>Change <em>Encoding</em> to reflect the character encoding of the input text. Even then, it may not work or some characters may not display properly because of variable browser support and because of the form interface. Developers can write some PHP code to capture the filtered input to a file if this is important.
<br /><br />Refer to the htmLawed documentation (<a href="htmLawed_README.htm"><span class="notice">htm</span></a>/<a href="htmLawed_README.txt"><span class="notice">txt</span></a>) for details about <em>Settings</em>, and htmLawed's behavior and limitations. For <em>Settings</em>, incorrectly-specified values like regular expressions are silently ignored. One or more settings form-fields may have been disabled. Some characters are not allowed in the <em>Spec</em> field.


<br /><br />Hovering the mouse over some of the text can provide additional information in some browsers.</small>

<?php
if($_w3c_validate){
?>

<small><br /><br />Because of character-encoding issues, the W3C validator (anyway not perfect) may reject validation requests or invalidate otherwise-valid code, esp. if text was copy-pasted in the input box. Local applications like the <em>HTML Validator</em> Firefox browser add-on may be useful in such cases.</small>
