<pre><?php

<?php

<p>If you would like to validate the code with
<a href="http://validator.w3.org/#validate-by-input">W3C's
validator</a>, copy and paste the <em>entire</em> demo page's source.</p>

<p>Welcome to the live demo. Enter some HTML and see how HTML Purifier
will filter it.</p>
<?php
}

<form id="filter" action="demo.php<?php

}
?></textarea>
<?php if (getFormMethod() == 'get') { ?>
<p><strong>Warning:</strong> GET request method can only hold
8129 characters (probably less depending on your browser).
If you need to test anything
larger than that, try the <a href="demo.php?post">POST form</a>.</p>
<?php } ?>
<?php if (extension_loaded('tidy')) { ?>
<div>Nicely format output with Tidy? <input type="checkbox" value="1"
name="tidy"<?php if (!empty($_REQUEST['tidy'])) echo ' checked="checked"'; ?> /></div>
<?php } ?>
<div>XHTML 1.0 Strict output? <input type="checkbox" value="1"
name="strict"<?php if (!empty($_REQUEST['strict'])) echo ' checked="checked"'; ?> /></div>
<div>Serve as application/xhtml+xml? (not for IE) <input type="checkbox" value="1"
name="xml"<?php if (!empty($_REQUEST['xml'])) echo ' checked="checked"'; ?> /></div>
<div>
<input type="submit" value="Submit" name="submit" class="button" />
</div>
</fieldset>
</form>
<p>Return to <a href="http://hp.jpsband.org/">HTML Purifier's home page</a>.
Try the form in <a href="demo.php?get">GET</a> and <a href="demo.php?post">POST</a> request
flavors (GET is easy to validate with W3C, but POST allows larger inputs).</p>
