获取 XML 内文 [英] Get XML Innertext

问题描述

我有一个这样的 xml 文件:

I have an xml file like that :

<?xml version="1.0" encoding="utf-8"?>
<KWS>
  <KW>
    <KWNAME>"make money online youtube video"</KWNAME>
    <GSC>318,000</GSC>

    <TOP10>6</TOP10>
    <TOP100>61</TOP100>
    <SEARCH-US-C>0</SEARCH-US-C>
    <NOTE>

      </YT-LINK>
    </YTLINKS>
  </KW>
</KWS>

我的 C# 代码用于获取 YT-LINK 中的每个链接

My C# code to get every LINK inside YT-LINK

        XmlDocument xml = new XmlDocument();
        xml.Load(file);

        XmlNodeList nodes = xml.SelectNodes("//KW");

        foreach (XmlNode node in nodes)
        {
            KWDATA k = new KWDATA();

            k.KEYWORD = node.SelectSingleNode("KWNAME").InnerText;
            k.GSC = node.SelectSingleNode("GSC").InnerText;
            k.YTC = node.SelectSingleNode("YSC").InnerText;
            k.N_VIDEOS_TOP_10 = node.SelectSingleNode("TOP10").InnerText;
            k.N_VIDEOS_TOP_100 = node.SelectSingleNode("TOP100").InnerText;
            k.N_OF_KW_SEARCH_IN_GOOGLE = node.SelectSingleNode("SEARCH-US-C").InnerText;

            List<string> YT_LINKS = new List<string>();
            foreach (XmlNode node2 in node.SelectNodes("YTLINKS")) // <-- i know something is wrong here
            {
                MessageBox.Show(node2.SelectSingleNode("YT-LINK").InnerText);
                YT_LINKS.Add(node2.SelectSingleNode("YT-LINK").InnerText);
            }
            k.YTLINKS = YT_LINKS;

但我只得到每个条目的第一个链接，例如:

but i only get the first link for each entry like :

http://www.youtube.com/watch?v=Dh5vptODX-M
http://www.youtube.com/watch?v=ij34hCOMiIU

只有，其余的不会被检索.

Only and the rest won't be retrieved.

推荐答案

YTLINKS"节点是单个节点，您可以先选择那个节点，然后遍历其中的YTLINK"节点集合:

The "YTLINKS" node is a single one, you can select that one first, then iterate through the collection of "YTLINK" nodes within:

var ytlinks = node.SelectSingleNode("YTLINKS");

foreach (XmlNode node2 in ytlinks.SelectNodes("YTLINK"))
{           
    YT_LINKS.Add(node2.InnerText);
}
