Snippet of day: 用xpath 查找特定节点的下一个节点

    public static void RunSnippet()
    {
        string xml_str = @"




";
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(xml_str);
        // Find the element which has a preceding sibling with attribite dever

        string xpath = "//a[ preceding-sibling::*[@name='dever'] ]";
        XmlElement ma = doc.SelectSingleNode(xpath) as XmlElement;
        if(ma != null)
        {
        WL( ma.OuterXml );
        }
    }


要查找要节点本身并没有特别的特征, 因此不能在xpath中指定其查找条件, 条件在于它前面的兄弟节点的特征, 希望找到这样的节点之下的节点, 上面的办法还有点绕, 其实可以用更直观的:

string xpath = "//a[ @name='dever']/following-sibling::a/following-sibling::a";

查找到该节点开始的第二个兄弟节点, 不过没办法指定数字来循环, 想要第10个兄弟节点时就累了.
