本文介绍了嗨伙计们有谁知道我怎么做，让我的Xmlnodelist在Foreach中。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

您好我有问题，我想在我的xmlnode foreach中得到我的xmlnodelist，因为我有反击它，我需要得到addon属性匹配文本框和节点的id 。

我的最终目标是一个篮子。我计算文本框中的数字并计算，它的价格来自一个名为AddonPrice的xmlnode。

现在我只得到第一个插件而不是其他两个，所以它现在看起来像这样。



类型：票数： 1价格：178总价：178



和计数工作正常，但只有第一个节点。我想我的问题是这行doc.SelectNodes（TourInfo / AddOns / AddOn [@ Id ='+ id +']）;.因为它在我的foreach之外所以id计数总是为0.所以我需要帮助才能把它放到我的foreach里面，或者用其他方式做吧:)



< pre lang =c＃> string id = addon + count;
string addon;

XmlNodeList nodeListADDon = doc.SelectNodes（ TourInfo / AddOns / AddOn [@ Id =' + id + ']）;
litTotal.Text = ;
litAdd.Text = ;
foreach （XmlNode nodeA in nodeListADDon）
{

addon = Request.Form [ txtAddonAntal + count];
antal = int .Parse（addon.ToString（））;

pris = int .Parse（nodeA [ AddonPrice]的innerText）。
ansver + = antal * pris;
总计+ = ansver;

litTotal.Text + = total.ToString（）+ & nbsp; kr ;
litAdd.Text = < table class = table table-condensed >< tr> + < span class =code-string>< td> + nodeA [ AddonText]。InnerText + < / td> + < td> + antal.ToString（）+ < / td> + < td> Pris： & nbsp; + ansver.ToString（）+ & nbsp; kr< / td> + < / tr>< / table>< br />;
count ++;
}

解决方案

好的 - 我明白了：



你是对的。列表节点列表仅针对1个id迭代一次。尝试将其包装在中循环：



如果正在迭代id 





  for （ int  x =  0 ; x< doc.SelectNodes（  TourInfo / AddOns / AddOn）。计数; x ++）
 {
 
  string  addon ; 
 
 XmlNodeList nodeListADDon = doc.SelectNodes（  TourInfo / AddOns / AddOn [@ Id ='插件 + x +  ']）; 
 litTotal.Text =  ; 
 litAdd.Text =  ; 
  foreach （XmlNode nodeA  in  nodeListADDon）
 {
 
 addon = Request.Form [  txtAddonAntal + x]; 
 antal =  int  .Parse（addon.ToString（））; 
 
 pris =  int  .Parse（nodeA [  AddonPrice]的innerText）。 
 ansver + = antal * pris; 
总计+ = ansver; 
 
  //  为清晰起见而格式化 
 litTotal.Text + = total.ToString（）+  & nbsp; kr; 
  string  text =  < table class =表格精简 >< tr> 
 text + =  < td> + nodeA [   AddonText]。InnerText +   < / td> 
 text + =  < td> + antal.ToString（）+  < / td> 
 text + =  < td> Pris：& nbsp; + ansver.ToString（）
 text + =  & nbsp; kr< / td> 
 text + =  < / tr>< / table>< br />< /跨度>; 
 
 litAdd.Text = text; 
 
} 
}









更新：我现在可以访问OP源代码：





  private   static   void  testsss（）
 {
 XmlDocument doc =  new  XmlDocument（）; 
 doc.Load（ @  C：\ nrd Party\testsss.xml ）; 
 
  int  total =  0 ; 
 
 litTotal.Text =  ; 
 litAdd.Text =  ; 
 
  //  错误处理 
  var  allAddonNodes = doc.SelectNodes（  TourInfo / AddOns / AddOn ）; 
  if （allAddonNodes ==  null ）
 返回; 
 
  for （ int  x =  0 ; x <  allAddonNodes.Count; x ++）
 {
  string  textBoxname =  string  .Format（  txtAddonAntal {0}，x）; 
 
 XmlNode addonNode = allAddonNodes [x]; 
  //  错误处理 
  if （addonNode [  AddonPrice] ==  null ）
 继续; 
 
  //  错误处理 
  int  antal; 
  if （！int.TryParse（Request.Form [textBoxname]， out  antal）） 
 继续; 
 
  //  错误处理 
  int  pris; 
  if （！int.TryParse（addonNode [  AddonPrice]。InnerText， out  pris））
  continue ; 
 
  var  ansver = antal * pris; 
总计+ = ansver; 
 
 
  var  nodeAAddonText = addonNode [  AddonText]; 
 
  string  nodeAInnerText = nodeAAddonText ==  null ？  ：nodeAAddonText.InnerText; 
 
  //  此行似乎不合适 
 litAdd。 Text =  string  .Format（FormatText，nodeAInnerText，antal，ansver）; 
 
} 
 litTotal.Text =总计+  @ & nbsp; kr ; 
}









最终更新：有关一些想法litAdd：



 private static void testsss（）
 {
 //如果你有一个表包含在标记中然后在服务器
 //运行它并改为使用它。下面的方法有点像黑客。 
 
 //我们将使用它将表标记写入字符串。这是hack部分
 StringBuilder sb = new StringBuilder（）; 
 HtmlTextWriter writer = new HtmlTextWriter（new StringWriter（sb，CultureInfo.InvariantCulture））; 
 
 //在hack中使用的表
 HtmlTable table = new HtmlTable（）; 
 table.Attributes.Add（class，table table-condensed）; 
 
 
 
 XmlDocument doc = new XmlDocument（）; 
 doc.Load（@C：\ 3rd Party\testsss.xml）; 
 
 int total = 0; 
 
 litTotal.Text =; 
 litAdd.Text =; 
 
 //错误处理
 var allAddonNodes = doc.SelectNodes（TourInfo / AddOns / AddOn）; 
 if（allAddonNodes == null）
 return; 
 
 for（int x = 0; x< allAddonNodes.Count; x ++）
 {
 //创建一个新表行
 HtmlTableRow row = new HtmlTableRow（ ）; 
 //要添加到行的单元格实例。 
 HtmlTableCell单元格; 
 
 string textBoxname = string.Format（txtAddonAntal {0}，x）; 
 
 XmlNode addonNode = allAddonNodes [x]; 
 //错误处理
 if（addonNode [AddonPrice] == null）
 continue; 
 
 //错误处理
 int antal; 
 if（！int.TryParse（RequestForm [textBoxname]，out anntal））
 continue; 
 
 //错误处理
 int pris; 
 if（！int.TryParse（addonNode [AddonPrice]。InnerText，out pris））
继续; 
 
 var ansver = antal * pris; 
总计+ = ansver; 
 
 
 var nodeAAddonText = addonNode [AddonText]; 
 
 string nodeAInnerText = nodeAAddonText == null？ ：nodeAAddonText.InnerText; 
 
 cell = new HtmlTableCell（）; 
 cell.InnerText = nodeAInnerText; 
 row.Cells.Add（cell）; 
 
 cell = new HtmlTableCell（）; 
 cell.InnerText = antal.ToString（）; 
 row.Cells.Add（cell）; 
 
 cell = new HtmlTableCell（）; 
 cell.InnerText = string.Format（Pris：& nbsp; {0}& nbsp; kr，ansver）; 
 row.Cells.Add（cell）; 
 
 //将行添加到表
 table.Rows.Add（row）; 
 
} 
 
 //如果表已经存在，那么页面渲染将绘制它，行和单元格
 //在呈现页面时。在这个hack中，它不在页面中，所以我们必须自己渲染
 //并获取html。这是一个黑客（但很好;）
 
 table.RenderControl（writer）; 
 
 litAdd.Text = sb.ToString（）; 
 
 litTotal.Text = total + @& nbsp; kr; 
}


Hi i have a problem, i want to get my xmlnodelist inside my xmlnode foreach somehowe because i have counter on it, an i need to get the of addon attribute match the id of textbox and nodes.
My final goal is a shooping basket. Where i count the number in the textbox and counting, it with the price that comes from an xmlnode called AddonPrice.
Right now i only get the first addon not the two others, so it looks like this right now.

Type:Ticket counts:1 price:178 total price: 178

and the counting works fine, but only with the first node. I think my problem is this line doc.SelectNodes("TourInfo/AddOns/AddOn[@Id='" + id + "']");. Because its outside my foreach so the id count will allways be 0. So i need help to get it inside my foreach or, do it some other way :)

string id = "addon" + count;
        string addon;
                
        XmlNodeList nodeListADDon = doc.SelectNodes("TourInfo/AddOns/AddOn[@Id='" + id + "']");
        litTotal.Text = "";
        litAdd.Text = "";
        foreach (XmlNode nodeA in nodeListADDon)
        {
         
            addon = Request.Form["txtAddonAntal" + count];
            antal = int.Parse(addon.ToString());

            pris = int.Parse(nodeA["AddonPrice"].InnerText);
            ansver += antal * pris;
           total += ansver;

            litTotal.Text += total.ToString() + "&nbsp;kr";
            litAdd.Text = "<table class="table table-condensed"><tr>" + "<td>" + nodeA["AddonText"].InnerText + "</td>" + "<td>" + antal.ToString() + "</td>" + "<td>Pris:&nbsp;" + ansver.ToString() + "&nbsp;kr</td>" + "</tr></table><br />";
            count++;
        }

解决方案

Ok - I see:

You are correct. The list nodelist is only iterated once for 1 id. Try wrapping this in a for loop:

if the id is being iterated


for(int x= 0;x<doc.SelectNodes("TourInfo/AddOns/AddOn").Count;x++)
{

        string addon;
                
        XmlNodeList nodeListADDon = doc.SelectNodes("TourInfo/AddOns/AddOn[@Id='addon" + x + "']");
        litTotal.Text = "";
        litAdd.Text = "";
        foreach (XmlNode nodeA in nodeListADDon)
        {
         
            addon = Request.Form["txtAddonAntal" + x];
            antal = int.Parse(addon.ToString());
 
            pris = int.Parse(nodeA["AddonPrice"].InnerText);
            ansver += antal * pris;
           total += ansver;
 
            //Formatted for clarity
            litTotal.Text += total.ToString() + "&nbsp;kr";
            string text = "<table class="table table-condensed"><tr>" 
            text += "<td>" + nodeA["AddonText"].InnerText + "</td>" 
            text += "<td>" + antal.ToString() + "</td>" 
            text += "<td>Pris:&nbsp;" + ansver.ToString() 
            text += "&nbsp;kr</td>" 
            text += "</tr></table><br />";

            litAdd.Text = text;

        }
}





UPDATE: I now have access to the OP source and code:


private static void testsss()
{
    XmlDocument doc = new XmlDocument();
    doc.Load(@"C:\3rd Party\testsss.xml");

    int total = 0;

    litTotal.Text = "";
    litAdd.Text = "";

    //Error handling
    var allAddonNodes = doc.SelectNodes("TourInfo/AddOns/AddOn");
    if (allAddonNodes == null)
        return;

    for (int x = 0; x < allAddonNodes.Count; x++)
    {
        string textBoxname = string.Format("txtAddonAntal{0}", x);

        XmlNode addonNode = allAddonNodes[x];
        //Error handling
        if (addonNode["AddonPrice"] == null)
            continue;

        //Error handling
        int antal;
        if (!int.TryParse(Request.Form[textBoxname], out antal))
            continue;

        //Error handling
        int pris;
        if (!int.TryParse(addonNode["AddonPrice"].InnerText, out pris))
            continue;

        var ansver = antal * pris;
        total += ansver;


        var nodeAAddonText = addonNode["AddonText"];

        string nodeAInnerText = nodeAAddonText == null ? "" : nodeAAddonText.InnerText;

        //This line seems out of place
        litAdd.Text = string.Format(FormatText, nodeAInnerText, antal, ansver);

    }
    litTotal.Text = total + @"&nbsp;kr";
}





FINAL UPDATE: Some ideas about litAdd:

private static void testsss()
{
    //If you have a table included in the markup then run that at server
    //and use that instead.  The method below is a bit of a hack.

    //We'll use this to write the table markup to a string.  This is the hack part
    StringBuilder sb = new StringBuilder();
    HtmlTextWriter writer = new HtmlTextWriter( new StringWriter(sb,CultureInfo.InvariantCulture));

    //table to use in the hack
    HtmlTable table = new HtmlTable();
    table.Attributes.Add("class", "table table-condensed");



    XmlDocument doc = new XmlDocument();
    doc.Load(@"C:\3rd Party\testsss.xml");

    int total = 0;

    litTotal.Text = "";
    litAdd.Text = "";

    //Error handling
    var allAddonNodes = doc.SelectNodes("TourInfo/AddOns/AddOn");
    if (allAddonNodes == null)
        return;

    for (int x = 0; x < allAddonNodes.Count; x++)
    {
        //create a new table row
        HtmlTableRow row = new HtmlTableRow();
        // a cell instance to add to the row.
        HtmlTableCell cell;

        string textBoxname = string.Format("txtAddonAntal{0}", x);

        XmlNode addonNode = allAddonNodes[x];
        //Error handling
        if (addonNode["AddonPrice"] == null)
            continue;

        //Error handling
        int antal;
        if (!int.TryParse(RequestForm[textBoxname], out antal))
            continue;

        //Error handling
        int pris;
        if (!int.TryParse(addonNode["AddonPrice"].InnerText, out pris))
            continue;

        var ansver = antal * pris;
        total += ansver;


        var nodeAAddonText = addonNode["AddonText"];

        string nodeAInnerText = nodeAAddonText == null ? "" : nodeAAddonText.InnerText;

        cell = new HtmlTableCell();
        cell.InnerText = nodeAInnerText;
        row.Cells.Add(cell);

        cell = new HtmlTableCell();
        cell.InnerText = antal.ToString();
        row.Cells.Add(cell);

        cell = new HtmlTableCell();
        cell.InnerText = string.Format("Pris:&nbsp;{0}&nbsp;kr", ansver);
        row.Cells.Add(cell);

        //add the row to the table
        table.Rows.Add(row);

    }

    //if the table exists already, then the page render will draw it, the rows and the cells
    //when the page is rendered.  In this hack it is not in the page so we have to render it
    //ourselves and get the html.  This is a hack (but a good one ;)

    table.RenderControl(writer);

    litAdd.Text = sb.ToString();

    litTotal.Text = total + @"&nbsp;kr";
}
