jQuery和XML是解析的最佳方式

尝试从Web服务vinquery.com解析XML结果时，值通常位于关键字名称之间，例如hello，但返回的XML为：

<?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）

或其他方法获取say

Item Key=“Body Style”

值的最有效方法是什么

谢谢

jQuery.parseXML（）：

---

使用属性过滤器，特别是attributeEquals过滤器：

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

varx='1〕\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
\
';
警报（$（x）.find（“项[Key='Body Style']））.attr（'Value'）；

您的意思是您尝试了jQuery的自动bultin XML解析，但遇到了性能问题吗？

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

var x='<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="Transmission-short" Value="5A | 5M" Unit="" />\

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