jQuery和XML最好的解析方法

Question

尝试解析来自Web服务vinquery.com的XML结果，通常这些值位于键名称之间，例如你好但是其返回的XML是：

<?xml version="1.0" encoding="utf-8" standalone="yes"?> 
<VINquery Version="1.0.0" Report_Type="BASIC" Date="1/19/2012"> 
    <VIN Number="1ZVFT80N475337065" Status="SUCCESS"> 
     <Vehicle VINquery_Vehicle_ID="32627" Model_Year="2007" Make="Ford" Model="Mustang" Trim_Level="V6 Deluxe Coupe"> 
      <Item Key="VINquery_Vehicle_ID" Value="32627" Unit="" /> 
      <Item Key="Model Year" Value="2007" Unit="" /> 
      <Item Key="Make" Value="Ford" Unit="" /> 
      <Item Key="Model" Value="Mustang" Unit="" /> 
      <Item Key="Trim Level" Value="V6 Deluxe Coupe" Unit="" /> 
      <Item Key="Manufactured in" Value="UNITED STATES" Unit="" /> 
      <Item Key="Production Seq. Number" Value="337065" Unit="" /> 
      <Item Key="Body Style" Value="COUPE 2-DR" Unit="" /> 
      <Item Key="Engine Type" Value="4.0L V6 SOHC 12V" Unit="" /> 
      <Item Key="Transmission-short" Value="5A | 5M" Unit="" /> 
      <Item Key="Transmission-long" Value="5-Speed Automatic | 5-Speed Manual" Unit="" /> 
      <Item Key="Driveline" Value="RWD" Unit="" /> 
      <Item Key="Tank" Value="16.00" Unit="gallon" /> 
      <Item Key="Fuel Economy-city" Value="18 - 19" Unit="miles/gallon" /> 
      <Item Key="Fuel Economy-highway" Value="26 - 28" Unit="miles/gallon" /> 
      <Item Key="Anti-Brake System" Value="Non-ABS | 4-Wheel ABS" Unit="" /> 
      <Item Key="Steering Type" Value="R&amp;P" Unit="" /> 
      <Item Key="Standard Seating" Value="4" Unit="" /> 
      <Item Key="Optional Seating" Value="No data" Unit="" /> 
      <Item Key="Length" Value="187.60" Unit="in." /> 
      <Item Key="Width" Value="74.00" Unit="in." /> 
      <Item Key="Height" Value="54.50" Unit="in." /> 
     </Vehicle> 
</VIN> 
</VINquery> 

什么是最有效的方式来获得使用$(xml)或其他的说Item Key="Body Style"的价值？

谢谢！

Answer 1

jQuery.parseXML（）：http://api.jquery.com/jQuery.parseXML/

var xmlDoc = $.parseXML(xmlstring);  
    $xml = $(xmlDoc);  
    $(xml).find("Item").each(function() { 
     if ($(this).attr("Key") == "Body Style") 
     { 
      alert($(this).attr("Value"));  
     } 
    } 

Answer 2

使用属性过滤器，尤其是attributeEquals过滤器：

$("node[Key='Bob Style']");

alert($(x).find("Item[Key='Body Style']").attr('Value'));
