比如 
price为19.95的author

Answer 1

XPATH也不能解决吗。
/bookstore/book[Price="19.95"]
这样至少能找到price为19.95的全部book出来
再想取得author不就水到渠成了

Answer 2

xmlpath就可以阿/bookstore/book[price='19.95'/author]

Answer 3

/bookstore/book[price='19.95']/author] 少了一括号

Answer 4

xmlpath拼路径  楼上说的很详细了

Answer 5

 /// <summary>
        /// 读取指定节点的值(InnerText)
        /// </summary>
        /// <param name="strNode">节点名称</param>
        /// <returns></returns>
        public string GetXmlNodeValue(string strNode)
        {
            string strReturn = String.Empty;
            try 
            {
                XmlNode xmlNode = xmlDoc.SelectSingleNode(strNode);
                if (xmlNode != null)
                {
                    strReturn = xmlNode.InnerXml;
                }
            }
            catch (XmlException xmle)
            {
                throw xmle;            
            }
            return strReturn;
        }
