XMLHttpRequest.responseXML 只读特性返回 Document containing the HTML or XML retrieved by the request; or null if the request was unsuccessful, has not yet been sent, or if the data can't be parsed as XML or HTML.

注意： 名称 responseXML is an artifact of this property's history; it works for both HTML and XML.

Usually, the response is parsed as " text/xml ". If the responseType is set to " document " and the request was made asynchronously, instead the response is parsed as " text/html ". responseXML is null for any other types of data, as well as for data: URL .

If the server doesn't specify the Content-Type as " text/xml " or " application/xml ", you can use XMLHttpRequest.overrideMimeType() to parse it as XML anyway.

This property isn't available to workers.

句法

var data = XMLHttpRequest.responseXML;
					

值

A Document from parsing the XML or HTML received using XMLHttpRequest ，或 null if no data was received or if the data is not XML/HTML.

异常

InvalidStateError

responseType isn't either " document " or an empty string.

范例

var xhr = new XMLHttpRequest;
xhr.open('GET', '/server');
// If specified, responseType must be empty string or "document"
xhr.responseType = 'document';
// Force the response to be parsed as XML
xhr.overrideMimeType('text/xml');
xhr.onload = function () {
  if (xhr.readyState === xhr.DONE && xhr.status === 200) {
    console.log(xhr.response, xhr.responseXML);
  }
};
xhr.send();

This was inconsistent with the specification. Starting with Firefox 51, this scenario now correctly returns null as per the spec.
