推荐答案

基于库 http://goessner.net/download/prj/jsonxml/，我实现了一个示例来接收XML数据并将其解析为Angular4应用程序:

Based on the library http://goessner.net/download/prj/jsonxml/, I implemented a sample to receive XML data and parse them into an Angular4 application:

var headers = new Headers();
(...)
headers.append('Accept', 'application/xml');

return this.http.get('https://angular2.apispark.net/v1/companies/', {
  headers: headers
}).map(res => JSON.parse(xml2json(res.text(),'  ')));

要使用该库，您需要首先解析XML字符串:

To be able to use the library, you need to parse first the XML string:

var parseXml;

if (typeof window.DOMParser != "undefined") {
  parseXml = function(xmlStr) {
    return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
  };
} else if (typeof window.ActiveXObject != "undefined" &&
   new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
      var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
      xmlDoc.async = "false";
      xmlDoc.loadXML(xmlStr);
      return xmlDoc;
  };
} else {
  throw new Error("No XML parser found");
}
