dom - 使用 XPath 到达特定类时如何停止查询？

Question

假设我有以下内容:

<div class="data">
    <h2 class="entry-contentH2">Preparation</h2>
    <h2>Airplanes</h2>
    <ul>
        <li><strong>3 large</strong> wings</li>
        <li><strong>2</strong>doors</li>
    </ul>
    <h2>Car</h2>
    <ul>
        <li><strong>4</strong> doors</li>
        <li><strong>1 cup</strong> holder</li>
    </ul>
    <h2 class="stopHeader">Execution</h2>
    <h2>Motorcycles</h2>
    <ul>
        <li>Easy to learn</li>
    </ul>
</div>

我正在尝试查询所有 <p></p> <h2>Preparing</h2> 之后的标签文本, 但我希望它停在最后 <p></p>在 stopHeader 类之前。

这是我想出的代码:

//h2[contains(.,"Preparation")]/following-sibling::h2/text()[not(preceding::h2[@class="stopHeader"])]

#and also
//h2[contains(.,"Preparation")]/following-sibling::h2/text()[not(preceding::h2[contains(., "Execution")])]

Answer 1

尝试以下 XPath 以获得所需的输出:

//h2[.="Preparation"]/following-sibling::h2[./following-sibling::h2[.="Execution"]]/text()

这应该返回 "Preparation" 和 "Execution"

之间每个标题 ( h2) 的文本内容
