如何使用Java在XML中标识节点的xpath？

我在树视图中填充了一个XML。当我单击某个特定节点时，我需要获取该特定节点的XPath。下面是示例XML。我已经试着写了一些代码，但是我没有得到确切的路径。请帮我解决它

    <?xml version="1.0" encoding="UTF-8"?>

我需要xpath输出，如下所示

//android.widget.LinearLayout[1]/android.widget.FrameLayout[2]/android.widget.LinearLayout[1]/android.widget.Button[1]

获取要获取的

xpath

节点，并将此函数应用于获取其

xpath

private String getXPath(Node node) {
    Node parent = node.getParent();
    if (parent == null) {
        return "/" + node.getTagName();
    }
    return getXPath(parent) + "/" + node.getTagName();
}

map

从何而来？map是全局声明的。没有“特定节点的XPath”。任何给定节点都有许多XPath表达式。我猜您正在寻找一个只选择那个节点，并且相当简洁的节点？对于XML的更改，它需要有多强大？谢谢。但假设某个节点有两个子节点，我需要数组专门指向该节点，否则下面的答案对我适用。我从下面的链接中得到了解决方案您在return语句中只将一个参数传递给getXPath（），但函数需要两个参数。谢谢。但假设某个节点有两个子节点，我将需要数组专门指向该节点。例如：//android.widget.LinearLayout[1]/android.widget.FrameLayout[2]/android.widget.LinearLayout[1]/android.widget.Button[1]@user3355101：很好，您已经提供了所需XPath类型的示例。你能把这个加到原来的问题上吗？

private String getXPath(Node node) {
    Node parent = node.getParent();
    if (parent == null) {
        return "/" + node.getTagName();
    }
    return getXPath(parent) + "/" + node.getTagName();
}
