Question

我有以下XML结构。我可以识别突出显示的<story contenttype="News" id="cbc655617-ba25-4629-b2a2-073ba2369758">个节点，我需要到达通过XPath突出显示的<packagesection id="264311652" navTitle="News">个节点。你能帮忙找一个可以识别相同的XPath表达式吗？我无法使用 navTitle 属性，因为它是动态的，但我只知道 packagesection 节点必须是<的最顶级父级的第一级子级< strong>故事节点

我尝试使用以下xpath并且它有效。感谢Paul的帮助!!

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

在XPath中选择特定节点
