如何获取具有某个标记名的所有ttk.Treeview节点的niid (tkinter)

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

treeview = ttk.Treeview(root)
treeview.pack()

# 添加节点及其标记名
treeview.insert("", "end", text="节点1", tags=("标记1",))
treeview.insert("", "end", text="节点2", tags=("标记2",))
treeview.insert("", "end", text="节点3", tags=("标记1", "标记3"))
treeview.insert("", "end", text="节点4")

def get_nodes_with_tag(tree, tag):
    nodes = []
    for item in tree.get_children():
        if tag in tree.item(item, "tags"):
            nodes.append(tree.item(item, "text"))
    return nodes

nodes_with_tag = get_nodes_with_tag(treeview, "标记1")
for node in nodes_with_tag:
    niid = treeview.item(treeview.focus(), "iid")
    print(f"节点 '{node}' 的 niid 为 {niid}")
