在 <br> 标记后获取字符串的 XPath 表达式

XPath expression to get a string after a <br> tag

我正在尝试获取 article/div/p 中的内容,但仅获取 <br> 标记之后的日期。这是怎么做到的?

<article>
    <h2>Man rescued after falling into Crater Lake</h2>
    <p class="summary highlight">
        Man rescued after falling 800 feet into Crater Lake in Oregon
    </p>

    <div class="body">
       <p>by Joe Sutton<br>
            June 11, 2019
        </p>
    </div>
</article>
$expression = "article/div/p";

这个 XPath,

//br/following-sibling::text()

select br.

之后的所有后续同级文本节点
