来自这个xml文档，它有两个评论列表。

但是我需要找到哪个评论的车名为Audi A1并提取该特定节点的数据（制造商，照片，段落）。



任何人帮我写xml解析器。

推荐答案

XDocument xDocument = XDocument.Parse(xml);

            string manufacturer = string.Empty;
            var aa = xDocument.Descendants("review").Where(x => x.Element("nameofcar").Value.Equals("Audi A1"));

            foreach (var a in aa)
            {
                manufacturer = a.Element("manufacturer").Value;
            }
