Question

我需要提取此XML文档的XML节点：

http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=michael%20jackson&song=bad

我无法弄清楚这一点。下面是我用来从该URL读取XML的当前代码。

private void button1_Click(object sender, RoutedEventArgs e)
{
    WebClient wc = new WebClient();
    wc.DownloadStringCompleted += HttpsCompleted;
    wc.DownloadStringAsync(new Uri("http://api.chartlyrics.com/apiv1.asmx/SearchLyricDirect?artist=michael%20jackson&song=bad"));
}

private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if (e.Error == null)
    {
        XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
        this.textBox1.Text = xdoc.LastNode.ToString();
    }
}

如何从提供的URL中访问XML文档中的节点lyric？

Answer 1

对于这种情况，请使用Linq To Xml。请注意，xml结果中有一个名称空间（xmlns="http://api.chartlyrics.com/"）。

一个非常基本的例子可能是：

void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if (e.Error == null)
    {
        XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
        var lyric = xdoc.Descendants(XName.Get("Lyric","http://api.chartlyrics.com/")).FirstOrDefault();

        this.textBox1.Text = lyric.Value;
    }
}
