Hi,
I have problem with PHP DOM extension. How can I add my own javascript
to javascript tag?
I tried it using this code
$html = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\"
\"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">\n" .
" \n" .
"<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\"
lang=\"en\">\n" .
"<head>\n" .
" <script type=\"text/javascript\" language=\"Javascript\" />\n" .
"</head>\n" .
"<body>hello\n" .
"</body>\n" .
"</html>";
$dom = new DomDocument();
$dom->preserveWhiteSpace = true;
$dom->loadXML($html);
$params = $dom->getElementsByTagName('script');
foreach ($params as $param) {
$dat = $dom->createTextSection("\n\nalert('ddd');\n\n");
$param->appendChild($dat);
}
echo $dom->saveXML();
but it encloses it to CDATA section automatically like this:
<script type="text/javascript"
language="Javascript"><![CDATA[alert('ddd');]]></script>
but I need it like this (because otherwise the javascript don't work):
<script type="text/javascript" language="Javascript">
//<![CDATA[
alert('ddd');
//]]>
</script>
Thanks for any idea,
Petr
