在 Google Apps 脚本上解析 XML

Question

这是我的 XML：

<?xml version="1.0" encoding="UTF-8" ?> 
<response>
    <records>
        <record id='1'>
            <column name="Name"><value><![CDATA[John]]></value></column>
            <column name="Email"><value><![CDATA[john@gmail.com]]></value></column>
        </record>
        <record id='2'>
            <column name="Name"><value><![CDATA[Joe]]></value></column>
            <column name="Email"><value><![CDATA[joe@gmail.com]]></value></column>
        </record>
    </records>
</response>

而且，这是我尝试解析上述 XML 并将名称和电子邮件作为数组返回：

var document = XmlService.parse(the_above_xml);
var root = document.getRootElement();
var atom = XmlService.getNamespace('http://www.w3.org/2005/Atom');
var records_all = document.getRootElement().getChildren('records', atom);
for (r=0; r<records_all.length; r++){
    var records = records_all[i].getChildren('record', atom);
    for (i=0; i< records.length; i++){
        columns = records[i].getChildren('column', atom);
        for (c=0; c< columns.length; c++){
            // I'm stuck here. I want to return an array of name and emails. 
        }
    }
}

我正在经历https://developers.google.com/apps-script/reference/xml-service/ 并且无法弄清楚如何实现它。我该如何解决？

Answer 1

怎么样：

function getRecords(xml) {
  var xmlDoc = XmlService.parse(xml);

  var response = xmlDoc.getRootElement();
  var records = response.getChild('records');
  var recordList = records.getChildren('record');

  var output = [];
  for (var i = 0, record; record = recordList[i]; i++) {
    var columnList = record.getChildren('column');
    var name = '';
    var email = '';
    for (var j = 0, column; column = columnList[j]; j++) {
      var attrName = column.getAttribute('name').getValue();
      var text = column.getChild('value').getText();
      if (attrName === 'Name') {
        name = text;
      } else if (attrName === 'Email') {
        email = text;
      }
    }
    output.push([name, email]);
  }
  return output;
}

此函数接受一个字符串参数，即您的 XML，并返回一个二维数组，数组的每一行都是姓名和电子邮件地址对。
