Reading an XML in C#

Question

I'm using System.Xml to read a xml file in C#. First I open the file (locally)... and use foreach to get the values, like this:

XmlNodeList titles = xmlDoc.GetElementsByTagName("title");
foreach (XmlNode title in titles)
{
rowNews = new ListViewItem();
rowNews.Text = (title.ChildNodes[0].Value);
listView1.Items.Add(rowNews);
}

The problem is, I have many rss tags called title in my file, I'd like to read only those what are inside <entry></entry> ?

Answer 1

Usually its easier to use XPaths in this case, so your code would look something like this:

XmlNodeList titles = xmlDoc.SelectNodes("//entry/title");
foreach (XmlNode title in titles)
{
rowNews = new ListViewItem();
rowNews.Text = (title.ChildNodes[0].Value);
listView1.Items.Add(rowNews);
}

Answer 2

I suggest using XDocument in the System.Xml.Linq namespace.

Then you can simply write document.Elements("entry").Elements("title")

Answer 3

这是一个提示：看看你如何遍历第一个“标题”节点。

Answer 4

您是否尝试过类似入口/标题的xpath？

Answer 5

请参见ParentNode和LocalName属性：

if (title.ParentNode.LocalName == "entry") { ... }
