如何在TreeView上按名称获取属性

# 导入必要的库
from tkinter import ttk

# 创建一个TreeView控件
tree = ttk.Treeview()

# 添加一些节点和属性
tree.insert("", "0", "node1", text="Node 1")
tree.set("node1", "attribute1", "Value 1")
tree.set("node1", "attribute2", "Value 2")

tree.insert("node1", "end", "node2", text="Node 2")
tree.set("node2", "attribute1", "Value 3")
tree.set("node2", "attribute2", "Value 4")

# 按名称获取属性的函数
def get_attribute_by_name(tree, node_name, attribute_name):
    # 遍历所有节点
    for node in tree.get_children():
        # 检查节点名称是否匹配
        if tree.item(node, "text") == node_name:
            # 获取节点的属性集合
            attributes = tree.item(node)
            # 检查属性名称是否存在
            if attribute_name in attributes["values"]:
                # 获取属性的值
                attribute_value = attributes["values"][attribute_name]
                return attribute_value

    # 如果未找到匹配的节点或属性，返回None
    return None

# 调用函数获取属性值
attribute_value = get_attribute_by_name(tree, "Node 1", "attribute1")
print(attribute_value)  # 输出: Value 1
