DOMDocument::createAttributeNS — Create new attribute node with an associated namespace
This function creates a new instance of class DOMAttr. This node will not show up in the document unless it is inserted with (e.g.) DOMNode::appendChild().
namespaceThe URI of the namespace.
qualifiedName The tag name and prefix of the attribute, as prefix:tagname.
DOM_INVALID_CHARACTER_ERR Raised if qualifiedName contains an invalid character.
DOM_NAMESPACE_ERR Raised if qualifiedName is a malformed qualified name, or if qualifiedName has a prefix and namespace is null.
| Version | Description |
|---|---|
| 8.3.0 | Calling this method without specifying a prefix will now choose a prefix instead of assuming the default namespace. Previously this would create an attribute without a prefix and incorrectly apply the namespace to the owner element because default namespaces don't apply on attributes. |
| 8.3.0 | Calling this method using a prefix that was already declared on the owner element with a different namespace URI will now change the new prefix to avoid creating namespace conflicts. This aligns the behaviour with the DOM specification. Previously this threw a DOMException with code DOM_NAMESPACE_ERR. |
