私は「画像」の子ノードを読み取るために管理することができませんでしたしてみてください何でも、しかし

textReader.ReadToFollowing("original_name"); 
string title =textReader.ReadElementContentAsString("original_name",textReader.NamespaceURI); 

を使用して、すべての属性を読んでいます。

あなたが最初<image>子孫に読み、その後、あなたはもうできなくなるまで次の兄弟に読み、<images>要素に読んでください。以下のコードは、これをどのように行うことができるかを示しています。

Answer 2

は、これらのオブジェクトを利用してみてください。

XmlDocument xml = new XmlDocument(); 
XmlNodeList nodes = xml.ChildNodes; 
XmlNode node = nodes[0]; 
XmlNode childNode = node.ChildNodes[0];
