How to add white space and " = " sign in XML createElement

Question

I am using PHP to generate XML file. I have to add space and = sign in XML node name like below

<a name="someName">someValue</a>

but it is showing Invalid Character Error when I use code as

$parentnode->appendChild($dom->createElement('a name="somName"'));

Answer 1

Because createElement() only accept tag name and text content of tag as parameter and you should use setAttribute() to add attribute to element.

$element = $dom->createElement("a");
$element->setAttribute("name", "somName");
$parentnode->appendChild($element);
