XMLElement

SimpleXMLElement wrapper, adding: namespace-prefixed attribute/child access ('ns:name'), parent/sibling navigation, a self-contained toXML serializer, and various convenience mutators SimpleXMLElement itself lacks (setAttribute, addElement, removeAttribute, ...).

class MMO\core\helpers\XMLElement extends SimpleXMLElement

You need to call static method FromString or FromFile to load correctly the xml.

$xml = XMLElement::FromString('<root a="1"><child>text</child></root>'); $xml->getAttribute('a'); // '1' $xml->getChild('child')->getInnerText(); // 'text'

addElement($tag, $attributes, $children)

XMLElement.php:247

Add child element (prefix supported)

function addElement( string $tag, array $attributes = [], SimpleXMLElement|string ...$children ): static

<foo:a>Apple</foo:a> $this->addElement('foo:a');

addNamespace($prefix, $namespace)

XMLElement.php:80

Declare a namespace on this element (xmlns:$prefix="$namespace"), without leaving a dummy attribute behind (a standard SimpleXML add-then-unset trick). NOTE: due to a SimpleXML quirk, getNamespaces may not immediately reflect the new declaration without re-parsing the XML -- asXML / toXML output does include it right away.

function addNamespace(string $prefix, string $namespace): self

$prefix	string	the prefix name
$namespace	string	the namespace uri
retourne	self	$this, for chaining

$node->addNamespace('foo', 'http://example.com/foo');

addXML($xml, $namespace)

XMLElement.php:276

Add xml to this node

function addXML(SimpleXMLElement|string $xml, ?string $namespace = null): self

$xml	SimpleXMLElement \| string
$namespace = null	null \| string
retourne	self	the created node

staticXMLElement.php:24

static function FromString( string $xml, int $options = 0, string $namespace_or_prefix = '', bool $is_prefix = false ): static

$xml	string	if it doesn't already start with an XML declaration, one (UTF-8) is prepended
