C# 通过Xpath搜索Xml节点列表，并在嵌套的GridView中绑定

我只想将xml绑定到gridview中的哪个多个子节点像这样

没关系，但当我在gridview中绑定嵌套的gridview以获取行数据绑定上的变量时

就这样,

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");
        }
}

它将为对象（即产品SkU ID=DL-DL4000和DL-DL4002）选择所有变体节点，但我只想逐个选择一个对象

---

请提供帮助基本上，您可以使用xpath谓词（

[]

）来筛选特定条件的元素。例如：

string sku=“DL-DL4002”；
stringxpath=string.Format（“/Products/Product[SKU='{0}']/Variants/Variant”，SKU）；
XmlNodeList nodeList=xmldoc.DocumentElement
.SelectNodes（xpath）；

上述示例将从

产品

返回

变量

，且

SKU

等于

“DL-DL4002”

。我不熟悉ASP.NET gridview，但您应该能够从

e.Row

参数中获取当前

SKU

值

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");
        }
}
