Question

HTML结构：

<div class="title">
    <h1>Some title</h1>
</div>    
<div class="row">something</div>

... (repeats the same structure)

<div class="title">
    <h1>Another title</h1>
</div>    
<div class="row anotherclass">1 something</div>
<div class="row">2 something</div>
<div class="row">3 something</div>

<div class="title">
    <h1>Some title</h1>
</div>    
<div class="row">something</div>

如何获取前一个标题（h1）与我的$search匹配的所有div（带有“row”类“）？

我现在所拥有的（不适用于最后一个元素，也不会停留在下一个标题）：

//div[child::h1[contains(text(), "<?php echo $search ?>")]]
/following-sibling::div[contains(concat(" ", normalize-space(@class), " "), " title ")]
/preceding-sibling::div[contains(concat(" ", normalize-space(@class), " "), " row ")]

如果我搜索“其他标题”，则输出应为：

<div class="row anotherclass">1 something</div>
<div class="row">2 something</div>
<div class="row">3 something</div>

Answer 1

这是一个很长的问题：

//div[contains(concat(" ",@class," ")," row ")][preceding-sibling::div[contains(concat(" ",@class," ")," title ")][1][contains(h1,"<?php echo $search ?>")]]

我将它分成几部分：

你想要所有具有类行的div ...

//div[contains(concat(" ",@class," ")," row ")]

第一个前一个兄弟与一个类标题......

[preceding-sibling::div[contains(concat(" ",@class," ")," title ")][1]

有一个包含搜索查询的h1

[contains(h1,"<?php echo $search ?>")]]
