I need to edit the inside of the following comment tag so that I can change the location of the css file. This needs to be done through PHP. I have tried using the following code but I get invalid expression errors.
Comment Section:
<!--[if IE 6]><link rel="stylesheet" type="text/css" href="/Css/IE6.css" media="screen" /><![endif]-->
Code that does not work:
$csslist = $xpath->query("//<!--[if IE 6]>");
foreach($csslist as $css) {
$css->innertext = 'test';
}
Try "//comment()" to get all CommentNodes.
Note that the link element in the CommentNode is not a childNode of the commentNode but mere data:
libxml_use_internal_errors(TRUE);
$dom = new DOMDocument;
$dom->loadHTMLFile( 'http://www.nytimes.com/' );
libxml_clear_errors();
$xpath = new DOMXPath($dom);
foreach( $xpath->query('//comment()[contains(., "link")]') as $node)
{
var_dump( $node->data );
}
This will give:
string(135) "[if IE]>
<link rel="stylesheet" type="text/css" href="http://graphics8.nytimes.com/css/0.1/screen/build/homepage/ie.css">
<![endif]"
string(138) "[if IE 6]>
<link rel="stylesheet" type="text/css" href="http://graphics8.nytimes.com/css/0.1/screen/build/homepage/ie6.css">
<![endif]"
As you can see, the actual comment node is just the <!-- and --> parts. The remainder is just text. The [if IE]> is not part of the actual tag. It is character data.
