Question

I need to clean up chunks of HTML code (containing <tables>, <div>, <p>, <span id='something'>) into a more standardized HTML with no styling of the original HTML code, with no <tables> <div> <span>. One way of cleaning up can be to remove all original HTML tags except for <ul> <li> <ol> <br> <strong> and <td> <tr> will be replaced by <p>. The tags that remain will be stripped of classes, ids and attributes.

How can I do this? At the moment, I am using strip_tags() which removes all tags but squeezes everything remaining into a single line, making it hard to read.

Example HTML Code to Cleanup

<table cellpadding="0" cellspacing="0" width="100%">
<tr><td align="center">
<table cellpadding="0" cellspacing="0" width="850">
<tr valign="top">

Note: I’m using Codeigniter if this helps with any parsing functions that it has.

Answer 1

$doc = new DOMDocument();
$doc->loadHTML(...);
$xpath = new DOMXpath($doc);
$nodes = $xpath->query("//*");

$rtn = array();
foreach ($nodes as $node)
{
    switch ($node->nodeName)
    {
        case "ul":
        case "li":
        case "ol":
        case "br":
        case "strong":
            $rtn[] = $node->nodeValue;
            break;
    }
}
