Question

我只想将xml绑定到gridview中，这个多个子节点就像这样..

，当我用这样的gridview绑定它时，它没问题

 XmlDocument xmldoc = new XmlDocument();
  xmldoc.Load(Server.MapPath("~/XML/XM.xml"));
  XmlNodeList nodeList = xmldoc.SelectNodes("/Products/Product");

     foreach (XmlNode node in nodeList)
                {
                     DataRow dtrow = dt.NewRow();
                    dtrow["SKU"] = node["SKU"].InnerText;
                }

没问题，但是当我在gridview中为嵌套gridview绑定Row DataBound上的Varients

时像那样，

protected void GridXML_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

            GridView gv = (GridView)e.Row.FindControl("gvChildGrid");
            DataTable dt = new DataTable();
        XmlNodeList nodeList = xmldoc.DocumentElement.SelectNodes("/Products/Product/Variants/Variant");
        }
}

它将为两个对象选择所有变体节点，即产品SkU ID = DL-DL4000和DL-DL4002，但我只想选择一个对象，即逐个

请帮忙

基本上，您可以使用xpath谓词（h4 { color: blue; } article{ color: black; } aside{ color: purple; } aside p{ color: gray; } aside h4{ font-style: italic !important; color: yellow; } article h4{ color: brown; } section h4{ color: orange; }）来过滤特定条件的元素。例如：

[]

上面的示例将从string sku = "DL-DL4002"; string xpath = String.Format("/Products/Product[SKU='{0}']/Variants/Variant", sku); XmlNodeList nodeList = xmldoc.DocumentElement .SelectNodes(xpath); Variant返回Product，SKU等于"DL-DL4002"。我不熟悉ASP.NET gridview，但您应该能够从SKU参数中获取当前e.Row值。

通过Xpath和Bind在嵌套的GridView中搜索Xml NodeList
