如何在空手道中使用JavaScript函数实现基于标签的XML值查找

var xhttp = new XMLHttpRequest();
xhttp.open("GET", "xml_data.xml", false);
xhttp.send();
var xmlData = xhttp.responseXML;

var nameElements = xmlData.getElementsByTagName("name");
for (var i = 0; i < nameElements.length; i++) {
  var nameValue = nameElements[i].textContent;
  console.log(nameValue);
}

var personElements = xmlData.getElementsByTagName("person");
for (var i = 0; i < personElements.length; i++) {
  var idValue = personElements[i].getAttribute("id");
  if (idValue === "1") {
    var nameElement = personElements[i].getElementsByTagName("name")[0];
    var nameValue = nameElement.textContent;
    console.log(nameValue);
    break;
  }
}
