jQuery讀取xml錯誤

我正在嘗試使用jQuery和yahoo地圖服務編寫簡單的位置查找調用。即用戶將一個位置放入搜索框中，當他們綁定jQuery時，我將調用我的網站上的一個頁面，該頁面從yahoo返回XML。jQuery讀取xml錯誤

Geocode.aspx.cs

protected void Page_Load(object sender, EventArgs e) 
{ 
    var url= "http://local.yahooapis.com/MapsService/V1/geocode?appid=SjCk7UjV34H0L9VoW5dFEXFGvsQuKX0xwIPNBX.rY8XxrWZbIYeSScFGuMrJyen_QwGKpLk-&location=" + Request.QueryString["location"]; 

    var oBuilder = new StringBuilder(); 
    var oStringWriter = new StringWriter(oBuilder); 
    var oXmlReader = new XmlTextReader(url); 
    var oXmlWriter = new XmlTextWriter(oStringWriter); 
    while (oXmlReader.Read()) 
    { 
     oXmlWriter.WriteNode(oXmlReader, true); 
    } 
    oXmlReader.Close(); 
    oXmlWriter.Close(); 
    Response.Clear(); 
    Response.Write(oBuilder.ToString()); 
    Response.Flush(); 
    Response.End(); 
}

Geocode.aspx：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Geocode.aspx.cs" Inherits="Search_Geocode" %>

我的搜索頁面使用下面的jQuery代碼來調用這個頁面：

function findAddress() { 
    var address = document.getElementById('ctl00_ContentPlaceHolder1_Location').value; 

    if (address.length > 3) { 
     $.ajax({ 
      type: "GET", 
      url: "Geocode.aspx?location=" + address, 
      dataType: "xml", 
      success: function(xmlData) { 
       $(xmlData).find('Result').each(function() { 
        document.getElementById('ctl00_ContentPlaceHolder1_Lat').value = $(this)[0].selectSingleNode('Latitude').text; 
        document.getElementById('ctl00_ContentPlaceHolder1_Long').value = $(this)[0].selectSingleNode('Longitude').text; 
        document.getElementById("locationspan").innerHTML = $(this)[0].selectSingleNode('Address').text + '<br />' + $(this)[0].selectSingleNode('City').text + '<br />' + $(this)[0].selectSingleNode('State').text; 

        var mapList = document.getElementById("divAddressSelector"); 
        mapList.className = 'mapAddressSelectorHide'; 
       }); 
      }, 
      error: function(XMLHttpRequest, textStatus, errorThrown) { 
       alert(XMLHttpRequest + '--' + textStatus + '--' + errorThrown); 
      } 
     }); 
    } 
}

運行此代碼用以下文本生成一個文本框：undefinedparsererror - undefined

當我從我的地理編碼頁面創建一個XML文件，並指向jQuery的URL，而不是一切正常。

感謝您的任何幫助。

好，幾個小時的搜索我設法找到一個解決方案之後。問題在於生成XML。主要是HTTP狀態碼和其他位。因此，對於任何人尋找一個解決一個問題是這樣的：

Geocode.aspx.cs應該是這樣的，而不是：

protected void Page_Load(object sender, EventArgs e) 
{ 
    var url= "http://local.yahooapis.com/MapsService/V1/geocode?appid=SjCk7UjV34H0L9VoW5dFEXFGvsQuKX0xwIPNBX.rY8XxrWZbIYeSScFGuMrJyen_QwGKpLk-&location=" + Request.QueryString["location"]; 

    var oBuilder = new StringBuilder(); 
    var oStringWriter = new StringWriter(oBuilder); 
    var oXmlReader = new XmlTextReader(url); 
    var oXmlWriter = new XmlTextWriter(oStringWriter); 
    while (oXmlReader.Read()) 
    { 
     oXmlWriter.WriteNode(oXmlReader, true); 
    } 
    oXmlReader.Close(); 
    oXmlWriter.Close(); 


    // Remove all headers and data in the Response. 
    Response.Clear(); 
    //set the mime type 
    Response.ContentType = "text/xml"; 
    // Buffer output and send it out in one chunk. 
    Response.BufferOutput = true; 
    // Specify a successful HTTP status code. 
    Response.StatusCode = 200; 

    Response.Write(oBuilder.ToString()); 
}
