After parsing the XML content, a corresponding array object is returned, and the return type can be set through parameter settings [array, JSON] Default: array
Because it is based on simplexml_load_string, it is not very good at parsing XML with namespace and will lose the namespace content. The above is the conclusion obtained in the test. Subsequent versions will solve this problem.
这个可以满足一般的使用需求
