在线阅读XML内容的困难与Python，XML.Etree.Elementtree和Urllib

发布于 2025-01-23 16:59:51 字数 963 浏览 2 评论 0原文

我正在使用Python，XML.Etree.ElementTree和Urllib在RSS提要中在线阅读XML。我的代码似乎很简单，但没有给我我想要的结果无论我做什么，它总是返回XML流中的所有数据，

我为如何将特定字符串读取到列表中的更好建议，

请参见下面的代码

import xml.etree.ElementTree as ET
from urllib import request

title_list = []  


def main():
    try:
        response = request.urlopen("https://www.abcdefghijkl.xml")
        rsp_code = response.code
        print(rsp_code)
        if rsp_code == 200:
            webdata = response.read()
            print("1")
            xml = webdata.decode('UTF-8')
            print("2")
            tree = ET.parse(xml)
            print("3")
            items = tree.findall('channel')
            print("4")
            for item in items:
                title = item.find('title').text
                title_list.append(title)

            print(f"title_list 0 is, {title_list}")
            print("5")

    except Exception as e:
        print(f'An error occurred  {str(e)}')


main()

I am reading XML online in an RSS feed using python, xml.etree.ElementTree and urllib.
My code seems to be straightforward but is not giving me the results that I want
No matter what I do it always returns what looks like all the data in the XML stream

I am open to better suggestions on how to read specific strings into lists

see my code below

import xml.etree.ElementTree as ET
from urllib import request

title_list = []  


def main():
    try:
        response = request.urlopen("https://www.abcdefghijkl.xml")
        rsp_code = response.code
        print(rsp_code)
        if rsp_code == 200:
            webdata = response.read()
            print("1")
            xml = webdata.decode('UTF-8')
            print("2")
            tree = ET.parse(xml)
            print("3")
            items = tree.findall('channel')
            print("4")
            for item in items:
                title = item.find('title').text
                title_list.append(title)

            print(f"title_list 0 is, {title_list}")
            print("5")

    except Exception as e:
        print(f'An error occurred  {str(e)}')


main()

谢谢，大家，我在一个很棒的udemy视频之后弄清楚了。我最终使用了BS4图书馆（美丽的汤）Python图书馆和请求。这是以下代码

import bs4
import requests

title_list = []


def main():
    try:
        result = requests.get("https://abcdefghijk.xml")
        res_text = result.text
        soup = bs4.BeautifulSoup(res_text, features="xml")
        title_tag_list = soup.select('title')
        for titles in title_tag_list:
            title = titles.text
            title_list.append(title)
     
        print(f"title_list 0 is, {title_list}")
        print("5")

    except Exception as e:
        print(f'An error occurred  {str(e)}')


main()

Thanks, everyone, I figured it out after an awesome Udemy video. I eventually used the bs4 library(beautiful soup)python library and requests. Heres the code below

import bs4
import requests

title_list = []


def main():
    try:
        result = requests.get("https://abcdefghijk.xml")
        res_text = result.text
        soup = bs4.BeautifulSoup(res_text, features="xml")
        title_tag_list = soup.select('title')
        for titles in title_tag_list:
            title = titles.text
            title_list.append(title)
     
        print(f"title_list 0 is, {title_list}")
        print("5")

    except Exception as e:
        print(f'An error occurred  {str(e)}')


main()
