java - 如何在 XML 中查找特定标签内的所有标签

转载作者：行者123 更新时间：2023-12-01 11:17:11

我想提取 <Page> 内的所有节点节点。我使用下面的方法通过以下两种方法查找 XML 文档中的所有节点

doc.getElementsByTagName("*");  //getting all the nodes
doc.getElementsByTagName("name"); //getting nodes <name>

但我想找到特定节点内的所有节点。例如我想要 <page> 内的所有节点。请建议我一种方法......

<Pages>

最佳答案

获取名称为 <page> 的所有节点

NodeList list = doc.getElementsByTagName("page");

如果有很多，则迭代它们并为每个获取子元素

for (Node node : list)
{
   //Get all nodes inside the this <page> element
   NodeList childList = node.getChildNodes();
}

如果您确实想要每个 <page> 中包含的所有节点，您将需要一个递归函数。这个将填充一个作为参数获取的列表:

public void getAllChildren(ArrayList<Node> list, Node parentNode)
{
    NodeList childList = parentNode.getChildNodes()
    for(Node node : childList)
    {
       list.add(node);
       getAllChildren(list, node);
    }
}

使用此功能

ArrayList<Node> allNodes = new ArrayList<Node>();

//Get the first node of all elements of <page>
Node pageNode = doc.getElementsByTagName("page").item(0);

getAllChildren(allNodes, pageNode);

//Now every child and child of child etc is on allNodes
