元素树无法访问没有名称空间的元素

问题描述 投票：0回答：1

我正在尝试使用元素树访问此XML文件中的元素，但我无法进入它。它甚至不识别它。

            for text in g_ns.findall("text"):
                print("textfound")

这是似乎不太行的两行。

import time
import xml.etree.ElementTree as ET

def main():

    tree = ET.parse('threetext.xml')
    root = tree.getroot()

    namespaces = {'p_link': 'http://www.evolus.vn/Namespace/Pencil',
                  'text_link': 'http://www.w3.org/2000/svg'}

    for content_ns in root.findall('p_link:Content', namespaces):
        print("content_ns Found!")
        for g_ns in content_ns.findall('text_link:g', namespaces):
            print("Id: " + g_ns.get("id") + "  Cords:"+ g_ns.get("transform"))
            for text in g_ns.findall("text"):
                print("textfound")

    print("suc")
    time.sleep(500);

main()

这是我正在使用的XML

感谢@mzjn的帮助，这是正确的

import time
import xml.etree.ElementTree as ET

def main():

    tree = ET.parse('menu.xml')
    root = tree.getroot()

    namespaces = {'p_link': 'http://www.evolus.vn/Namespace/Pencil',
                  'text_link': 'http://www.w3.org/2000/svg'}

    for content_ns in root.findall('p_link:Content', namespaces):
        print("content_ns Found!")
        for g_ns in content_ns.findall('text_link:g', namespaces):
            print("Id: " + g_ns.get("id") + "  Cords:"+ g_ns.get("transform"))
            for text in g_ns.findall("text_link:text", namespaces):
                print("textfound")

    print("suc")
    time.sleep(500);

main()
