Question

我想使用xpath检索位于另一个div内的div节点：

我的意见是：

    <div id="toolbar">

    <div class="linkTrail">
    <span class="trailLabel">You are here: </span>
    <a href="http://www.euromonitor.com/home">Home</a>
    <a href="http://www.euromonitor.com/solutions">Solutions</a>
    <a href="http://www.euromonitor.com/industries">Industries</a>
    <a href="http://www.euromonitor.com/home-care" class="last">Home Care</a>
    </div>
    <script type="text/javascript">var switchTo5x = false;</script>
    <script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script>
    <script type="text/javascript">  stLight.options({ publisher: 'c4fa7e97-6938-4efa-b3d0-b81551cc9ee3', tracking: 'google' });</script>
<div class="clear">
</div>

我希望输出为：

<div class="linkTrail">
<span class="trailLabel">You are here: </span>
<a href="http://www.euromonitor.com/home">Home</a>
<a href="http://www.euromonitor.com/solutions">Solutions</a>
<a href="http://www.euromonitor.com/industries">Industries</a>
<a href="http://www.euromonitor.com/home-care" class="last">Home Care</a>
</div>

我在xpath之后尝试了xpath来检索linktrail div：

//div[@class='toolbar']/div

但是它给了我错误的输出：

<div class="linkTrail">
    <span class="trailLabel">You are here: </span>
    <a href="http://www.euromonitor.com/home">Home</a>
    <a href="http://www.euromonitor.com/solutions">Solutions</a>
    <a href="http://www.euromonitor.com/industries">Industries</a>
    <a href="http://www.euromonitor.com/home-care" class="last">Home Care</a>
    </div>
    <script type="text/javascript">var switchTo5x = false;</script>
    <script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script>
    <script type="text/javascript">  stLight.options({ publisher: 'c4fa7e97-6938-4efa-b3d0-b81551cc9ee3', tracking: 'google' });</script>

可能是什么问题，是由于父div包含脚本。任何人都可以帮我解决这个问题。

就这么简单：

//div[@id='toolbar']/div[@class='linkTrail']

这会选择任何div，其class属性为"linkTrail"的字符串值，且div属性为字符串id的子项值"toolbar"

基于XSLT的验证：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="/">
     <xsl:copy-of select="//div[@id='toolbar']/div[@class='linkTrail']"/>
 </xsl:template>
</xsl:stylesheet>

将此转换应用于提供的XML文档时：

<div id="toolbar">
    <div class="linkTrail">
        <span class="trailLabel">You are here: </span>
        <a href="http://www.euromonitor.com/home">Home</a>
        <a href="http://www.euromonitor.com/solutions">Solutions</a>
        <a href="http://www.euromonitor.com/industries">Industries</a>
        <a href="http://www.euromonitor.com/home-care" class="last">Home Care</a>
    </div>
    <script type="text/javascript">var switchTo5x = false;</script>
    <script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script>
    <script type="text/javascript">  stLight.options({ publisher: 'c4fa7e97-6938-4efa-b3d0-b81551cc9ee3', tracking: 'google' });</script>
    <div class="clear"></div></div>

评估Xpath表达式并将评估结果（所选节点）复制到输出：

<div class="linkTrail">
   <span class="trailLabel">You are here: </span>
   <a href="http://www.euromonitor.com/home">Home</a>
   <a href="http://www.euromonitor.com/solutions">Solutions</a>
   <a href="http://www.euromonitor.com/industries">Industries</a>
   <a href="http://www.euromonitor.com/home-care" class="last">Home Care</a>
</div>

Answer 2

在XPath中，您将@class指定为“工具栏”，但@id具有该值。如果我调整表达式，我会得到你想要的输出加上“clear”div。

问题可能是div包含在与条件匹配的另一个div中。

检索xpath以选择其父节点包含java脚本的节点
