考虑这个
Beer <br> Vodka <br> rum <br> whiskey
你会如何在 xpath 中表达 Beer？
/br/preceding-sibling::text() ?
伏特加呢？朗姆酒 ？
取决于上下文。理想情况下，要成为格式良好的 XML，您的序列需要一个根元素。假设它是<bar/>.
<bar/>
啤酒：/bar/br[1]/preceding-sibling::text()[1]
/bar/br[1]/preceding-sibling::text()[1]
伏特加酒： /bar/br[1]/following-sibling::text()[1]
/bar/br[1]/following-sibling::text()[1]
朗姆酒：/bar/br[2]/following-sibling::text()[1]
/bar/br[2]/following-sibling::text()[1]
