sunny5156 / xml2array

Converts an XML DOMDocument to an array, and back.

Readme

Convert XML to an array representation, and then convert back to XML again.

Drop-in replacement for Lalit.org's XML2Array and Array2XML classes, based on their work.

• Configurable to use different special array keys for attributes/cdata/value
• Configurable to preserve tag and attribute namespaces
• Array to XML conversion automatically uses the root array element as the root XML node, if only one element exists at the top-level in the array

Usage Examples

Basic usage

$array = XML2Array::createArray($xml);
$xml = Array2XML::createXML($array);

Note that there's no need to specify the 'rootNode' parameter from the previous implementation. If the array contains a single root item, that will automatically be used as the root node.

Drop-in replacement

Of course, if you need a drop-in replacement, the old syntax works as before.

$array = XML2Array::createArray($xml);
$xml = Array2XML::createXML('rootNode', $array);

Preserve namespaces

$config = array(
    'useNamespaces' => true,
);
$array = XML2Array::createArray($xml, $config);

Use JSON-friendly special keys

$config = array(
    'attributesKey' => '$attributes',
    'cdataKey'      => '$cdata',
    'valueKey'      => '$value',
);
$array = XML2Array::createArray($xml, $config);
$xml = Array2XML::createXML($array, $config);
