xml和中繼器

Question

是否必須使用XPath將我的XML文檔 鏈接到中繼器，或者有其他方法。

這是我的一些代碼。通過數據和存儲

第一頁環路XML：

public virtual void Button_Click(object sender, EventArgs args) 
      { 

      TableControl recControls = (TableControl)this.Page.FindControlRecursively("TableControl"); 
       if (recControls != null) 
       { 
        TableControlRow[] rows = recControls.GetSelectedRecordControls(); 
        this.Page.Session["RegistrationTableControl"] = rows; 

        // create XML writer to 
        using(System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(@"c:\temp\reg.xml")) 
        { 
         XmlWriterSettings settings = new XmlWriterSettings(); 
         settings.OmitXmlDeclaration = true; 
         settings.ConformanceLevel = ConformanceLevel.Fragment; 
         settings.CloseOutput = false; 



         writer.WriteStartDocument(); 
         writer.WriteStartElement("SubContractors"); 
         foreach(TableControlRow rec in rows) 
         { 

          writer.WriteElementString("SubContrator1", rec.BUSINESSNAME.Text); 
          writer.WriteElementString("SubContactName1", rec.OWNERNAME.Text); 
          writer.WriteElementString("SubAddress1", rec.ADDRESS.Text); 
          writer.WriteElementString("SubCity1", rec.CITY.Text); 
          writer.WriteElementString("SubState1", rec.STATE.Text); 
          writer.WriteElementString("SubZipCode1", rec.ZIPCODE.Text); 
          writer.WriteElementString("SubPhone1", rec.PHONE.Text); 
          writer.WriteElementString("SubFax1", rec.FAX.Text); 
          writer.WriteElementString("SubEmail1", rec.EMAIL.Text); 
          writer.WriteElementString("Status1", "Please enter information"); 
          writer.WriteElementString("Referral", "1"); 

         } 
         writer.WriteEndElement(); 
         writer.WriteEndDocument(); 
       } 


       }} 

它創建我的XML文檔。代碼：我需要在新創建的XML文檔中獲取數據，然後使用此代碼填充我的表格控件中繼器。

public override void DataBind() 
    { 
     base.DataBind(); 


     // Make sure that the DataSource is initialized. 
     if (this.DataSource == null) 
     { 
      return; 
     } 
     // Setup the pagination controls. 
     BindPaginationControls(); 

     // Populate all filters data. 

     // Bind the repeater with the list of records to expand the UI. 
     System.Web.UI.WebControls.Repeater rep = (System.Web.UI.WebControls.Repeater)(this.FindControl("TableControlRepeater")); 
     rep.DataSource = this.DataSource; 
     rep.DataBind(); 

     int index = 0; 
     foreach (System.Web.UI.WebControls.RepeaterItem repItem in rep.Items) 
     { 

      // Make sure that the DataSource is initialized. 


      // Loop through all rows in the table, set its DataSource and call DataBind(). 
      TableControlRow recControl = (TableControlRow)(repItem.FindControl("TableControlRow")); 
      recControl.DataSource = this.DataSource[index]; 
      recControl.DataBind(); 
      recControl.Visible = !this.InDeletedRecordIds(recControl); 
      index += 1; 
     } 
    } 

對我採取XML數據並將其放置在成爲中繼器的數據源2頁。

任何幫助或建議是非常有益的。我真的不需要重寫代碼。

Answer 1

我用LINQ to XML

查詢XML文檔就容易多了。

Answer 2

LINQ-To-XML可能是完成此任務最簡單的方法。參見Scott Gu的post就可以了。

僞代碼：

var xml = XDocument.Load(...); 
reapeater.DataSource = from x in xml.Descendents("z") 
    where x.Attributes("y").Equals("select value") 
    select new { Value1 = x.Element("Value1"), Value2 = x.Element("Value2") }; 
repeater.DataBind();
