从xml获取数据集：
string sourceXML = "http://mydomain/myxmlfile.xml";
XmlReader xmlFile = XmlReader.Create(sourceXML, new XmlReaderSettings());
DataSet ds = new DataSet();
ds.ReadXml(xmlFile);
ds.Tables[0].TableName, article
ds.Tables[1].TableName, content
ds.Tables[2].TableName, photos
ds.Tables[3].TableName, photo
所以我尝试解析，我得到的文章，但所有的图片：

我想只获取每篇文章的照片，这是我尝试过的：
foreach (DataRow row in ds.Tables[0].Rows)
{
try
{
string element = row["type"].ToString();
article = new Article();
feed += element + " title: " + row["title"] + Environment.NewLine;
feed += element + " title: " + row["description"] + Environment.NewLine;
article.setTitle("<![CDATA[" + row["title"].ToString() + "]]>");
foreach (DataRow row1 in ds.Tables[3].Rows)
{
feed += row1["photoURL"] + Environment.NewLine;
}
listArt.Add(article);
i++;
}
catch (IndexOutOfRangeException ioe)
{
feed += "Error al crear " + sourceXML + Environment.NewLine;
feed += ioe.ToString() + Environment.NewLine;
}
}
textBox1.AppendText(feed);
答案 0 :(得分：0)
var q = from article in XDocument.Load(path)
.Root
.Elements("article")
let photos = article.Element("content")
.Element("photos")
.Elements("photo")
.Elements("photoURL")
select new
{
ArticleId = (string)article.Element("id"),
Photos = photos.Select(e => (string)e).ToArray()
};
用法：
foreach (var a in q)
{
Console.WriteLine(a.ArticleId);
foreach (var p in a.Photos)
{
Console.WriteLine(p);
}
}
