Question

HTML tidy or string replace

Asked by: us111

The code works but there are still warnings with anchors like <a name="1"> ?

Is it possible to clean this with tidy because the HTML code below is not XHTML valid ?

<a href="#1">test</a>
<a name="1"></a><h2>test</h2>

should be for instance

<a href="#a1">test</a>
<a name="a1"></a><h2>test</h2>

Any ideas how to clean this ?

$config = array('indent' => TRUE,
                'output-xhtml' => TRUE,
                'wrap' => 200,
				'drop-font-tags' => TRUE,
				'drop-proprietary-attributes' => TRUE,
				'logical-emphasis' => TRUE,
				'show-body-only' => TRUE,
				'word-2000' => TRUE,
				);
				
if ($_POST['code'] <> "")
{
	$code = $_POST['code'];
	
	$code = str_ireplace("align=\"center\"", "", $code);
	$code = str_ireplace("align=\"left\"", "", $code);
	$code = str_ireplace("align=\"right\"", "", $code);
	
	$code = @tidy_parse_string($code, $config);
	@$code->cleanRepair();
	echo tidy_warning_count($code);
	echo $code->errorBuffer;
}

If you're dealing with possibly invalid XHTML then you should really use something like HTMLPurifier which has a built in Tidy feature. It will correct and tidy the XHTML.

What are the warnings? Anchors are XHTML compliant. Maybe your warning relates to something else.

 

by: us111Posted on 2008-12-30 at 03:45:58ID: 23261804

yes anchors are compliant but not :

<a name="1" id="1">test</a>

An anchor or id should begin with a letter. Tidy returns a warning

 

by: bportlockPosted on 2008-12-30 at 04:07:27ID: 23261900

Try a regular expression. Here is a sample

<?php

$str = '<a name="1"></a><h2>test</h2><a name="2"></a><h2>test</h2><a name="333"></a><h2>test</h2><a name="4"></a><h2>test</h2>';
$replace = '<a name="a$1">';
$newStr = preg_replace('/<a name="([0-9]+)">/', $replace, $str );

echo htmlentities($newStr);
?>

Beware that prepending all numeric ids, names etc. with a letter might clash with an id="a1" that might already exist.
In other words, you'd have to prepend a letter to *all* ids, names etc.
Don't forget ids used in javascript to reference the DOM
Don't forget names used in server-side scripts to referrence form fields.
Don't forget anchored hrefs from third-party websites.
