在XPath中选择特定节点

我有以下XML结构。我可以确定突出显示的<story contenttype="News" id="cbc655617-ba25-4629-b2a2-073ba2369758">节点，并且需要到达通过XPath突出显示的<packagesection id="264311652" navTitle="News">节点。你可以请一个能够识别相同的XPath表达式来帮忙吗？我将无法使用navTitle属性，因为它是动态的，但我只知道packagesection节点必须是最顶层的父的第一级子为故事节点在XPath中选择特定节点

我曾尝试以下： /剧情/祖先:: packagesection [@ navTitle = '气日报']/sectionelement/packagesection ，我让所有packagesection元素 – ArinCool

什么'（// sectionelement/packagesection [@ navTitle ='Gas Daily'] //故事[predicate-to-filter-on-the-story-you-want]] [1]'？ –

感谢您的回复保罗。我需要获取packagesection元素而不是故事元素。请建议 – ArinCool

我试着用下面的xpath，它工作。感谢你保罗的帮助！

//sectionelement/packagesection[@navTitle="Gas Daily"]/sectionelement/packagesection[descendant::story[@id=$id] or descendant::analytic[@id=$id]]
