Question

下面是一些HTML代码，我需要在其中找到内容为win8的元素（最后一个元素<div class="desc">win8</div>）。

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable" style="display: block; z-index: 5002; outline: 0px none; position: absolute; height: auto; width: 800px; top: 7px; left: 537px;" tabindex="-1" role="dialog" aria-labelledby="ui-dialog-title-1">
<div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
<div class="multi-wizard instance-wizard ui-dialog-content ui-widget-content" style="width: auto; min-height: 0px; height: 518px;">
<div class="progress">
<form novalidate="novalidate">
<div class="steps">
<div class="step setup loaded" wizard-step-id="setup" style="display: none;">
<div class="step select-iso loaded" wizard-step-id="select-iso" style="display: block;">
<div class="wizard-step-conditional select-template" style="display: block;">
<div class="main-desc">
<div class="template-select content tab-view ui-tabs ui-widget ui-widget-content ui-corner-all">
<ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all">
<input type="hidden" value="XenServer" name="hypervisor" wizard-field="hypervisor">
<div id="instance-wizard-featured-templates" class="ui-tabs-panel ui-widget-content ui-corner-bottom">
<div class="select-container">
<div class="select **even**">
<input type="radio" name="templateid" wizard-field="template" value="b0c24832-6fdf-11e4-a45f-b6eb114441ae">
<div class="select-desc">
</div>
<div class="select **odd**">
<input type="radio" name="templateid" wizard-field="template" value="7720cdb2-b81a-4839-94cd-b56b660e3324">
<div class="select-desc">
<div class="name">win8</div>
<div class="desc">win8</div>
</div>
</div>

我尝试了以下XPath：

.//*[@id='instance-wizard-featured-templates']/div/div[2]/input

问题是屏幕有2个元素，偶数和奇数。每次加载它都会交换值。所以XPath选择了错误的元素。

有没有办法准确选择win8？

假设你总是希望获得名为'desc'的类的元素，那么正确的XPath看起来像这样：

//div[@class="desc" and text()="win8"]

这将选择具有“desc”和“win8”类的所有<div>个元素作为文本。

需要识别元素
