Question:
I'm trying to insert an HTML <base> tag immediately after the opening <head> tag of a page using dom. I've tried using appendChild which just inserts it before the </head> which is no good.
Code im using:
$head = $dom->getElementsByTagName('head')->item(0); $base = $dom->createElement('base'); $base->setAttribute('href', $url); $head->parentNode->insertBefore($base, $head); This inserts the <base> tag before the <head>, which is still no good!
Any ideas? Beer for the correct answer!
Solution:1
$head = $dom->getElementsByTagName('head')->item(0); $base = $dom->createElement('base'); $base->setAttribute('href',$url); if ($head->hasChildNodes()) { $head->insertBefore($base,$head->firstChild); } else { $head->appendChild($base); } If the <head> element already has children, it inserts the <base> element before <head>'s first child. If <head> has no children, it just appends it to <head>.
