Description
举例：https://club.autohome.com.cn/bbs/thread/86f2870bac840396/72293736-1.html
在浏览器审查元素-Console中输入
$x("//div[@class='conleft fl']/ul[@class='leftlist']/li[contains(text(),'帖子')]/a[1]/text()")
得到(7) [text, text, text, text, text, text, text]
而使用Webmagic集成的Xsoup
page.getHtml().xpath("//div[@class='conleft fl']/ul[@class='leftlist']/li[contains(text(),'帖子')]/a[1]/text()").all();
会得到一个空集合，求解

Research direction
Start by reproducing the XPath expression against the linked Autohome page in the browser console and through WebMagic's Xsoup call. Trace how Xsoup handles contains(text(),'帖子') and compare the selected nodes; done means the Xsoup query returns the expected text nodes or the limitation is clearly documented.
