              <departure-date-time>2015-03-17T10:40:00</departure-date-time>
              <layover-duration>1800</layover-duration>
          </stop-details>
      </stops-details>
    </segment>

我试过这样，但没有工作。任何帮助表示赞赏!!!!

var arr_tym =$(element).find('departure-date-time').text();

这对我有用，但在IE8中它不起作用

var arr_tym =$(element).find('arrival-date-time')[0].innerHTML

尝试使用:first仅选择第一个

＆＃13;

＆＃13;

var xml = '<segment> \
      <index>1</index> \
      <departure-airport>MAA</departure-airport> \
      <arrival-airport>IXB</arrival-airport> \
      <departure-date-time>2015-03-17T07:55:00</departure-date-time> \
      <arrival-date-time>2015-03-17T11:45:00</arrival-date-time> \
      <flight-number>503</flight-number> \
      <airline>6E</airline> \
      <operating-airline>6E</operating-airline> \
      <stops>1</stops> \
      <equipment>320 </equipment> \
      <duration>13800</duration> \
      <stops-details> \
          <stop-details> \
              <layover-airport>CCU</layover-airport> \
              <arrival-date-time>2015-03-17T10:10:00</arrival-date-time> \
              <departure-date-time>2015-03-17T10:40:00</departure-date-time> \
              <layover-duration>1800</layover-duration> \
          </stop-details> \
      </stops-details> \
    </segment>';

var arr_tym =$(xml).find('departure-date-time:first').text();
console.log(arr_tym);
