I have this xhtml :
<?xml version="1.0" encoding="UTF-8"?>
<html>
<head>
<meta charset="utf-8"></meta>
</head>
<body>
<nav>
<ol>
<li>
<a href="cover.xhtml">Cover</a>
</li>
<li>
<a href="page002.xhtml">P002</a>
</li>
<li>
<a href="page005.xhtml">P005</a>
</li>
<li>
<a href="page038.xhtml">P038</a>
</li>
</ol>
</nav>
</body>
</html>
I do this in php :
copy("nav.xhtml", "nav.xml");
$doc1 = simplexml_load_file("nav.xml");
foreach($doc1->body->nav->ol->li->a as $seg){
$dom=dom_import_simplexml($seg);
$dom->parentNode->removeChild($dom);
}
$doc1->asXml("nav.xhtml");
In result, just the fist is deleted. I would like to delete all . Why it's not correct?
Thanks.
Try this.
foreach($xml->body->nav->ol->li as $items)
{
unset($items->a);
}
This would be the DOM approach, I think it can save you troubles in the future:
$dom = new DOMDocument();
$dom->load($file);
$ol = $dom->getElementsByTagName('ol')->item(0);
$list_elements = $ol->getElementsByTagName('li');
foreach($list_elements as $li){
$links = $li->getElementsByTagName('a');
foreach($links as $a){
$li->removeChild($a);
}
}
$output = $dom->saveXML();
echo $output;
