jQuery 和 XML 解析的最佳方式

Question

尝试解析来自 Web 服务 vinquery.com 的 XML 结果，通常值位于键名之间，例如你好，但是返回的 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>

使用 $(xml) 或其他方式获取 say Item Key="Body Style" 值的最有效方法是什么？

谢谢!

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"));    
      }
   }
