在javascript中读取xml

var xhr = new XMLHttpRequest();

xhr.open("GET", "example.xml", true);

xhr.responseType = "document";

xhr.onload = function() {
  if (xhr.status === 200) {
    var xmlData = xhr.responseXML;
    // 在这里可以对XML数据进行处理
  }
};

xhr.send();

var xhr = new XMLHttpRequest();
xhr.open("GET", "example.xml", true);
xhr.responseType = "document";
xhr.onload = function() {
  if (xhr.status === 200) {
    var xmlData = xhr.responseXML;
    var books = xmlData.getElementsByTagName("book");
    for (var i = 0; i < books.length; i++) {
      var title = books[i].getElementsByTagName("title")[0].textContent;
      var author = books[i].getElementsByTagName("author")[0].textContent;
      console.log("Title: " + title + ", Author: " + author);
    }
  }
};
xhr.send();
