Convert XML into an array object

Convert XML into an array object

After the XML content is parsed, a corresponding array object is returned, and the return type [array, JSON] can be set through parameter settings. default value: Array Because simplexml_load_string-based parsing of XML with namespaces is not very good, the namespace content will be lost. the above is the conclusion obtained in the test. this problem will be solved in later versions. This can meet general needs.
