Hi, I want to set id of an element. I'm using php dom. I could not understand how following will work.
DOMElement::setIdAttribute ( string $name , bool $isId )
The only description I found for this in manual is - Declares the attribute name to be of type ID.
How can I do this ?
What about DOMElement::setAttribute? You could just setAttribute('id', 'your_id'), or am I missing something? After that, you could use setIdAttribute('id', TRUE) to mark it as the ID.
If you want to add an id attribute to your html element so that it looks like <p id="frob">... you dont use setIdAttribute() - it declares that the attribute $name can be used as an unique identifier for that element - as an alternative/addition of the id attribute. Use setAttribute() like so:
$dom = new DOMDocument();
$dom->loadHTML('<html><body><p>FROB</p></body></html>');
$dom->getElementsByTagName('p')->item(0)->setAttribute('id', 'XXX');
print $dom->saveHTML();
