如何批量更新Jenkins作业配置xml文件？

import requests
import xml.etree.ElementTree as ET

# Jenkins服务器的URL和API Token
jenkins_url = "http://your_jenkins_url"
api_token = "your_api_token"

# 获取所有作业的配置xml
response = requests.get(f"{jenkins_url}/api/xml?tree=jobs[name,url,config]", auth=("api_token", api_token))
jobs = ET.fromstring(response.content)

# 遍历每个作业的配置xml，更新需要修改的配置项
for job in jobs.iter("job"):
    job_name = job.find("name").text
    job_url = job.find("url").text

    # 获取作业的配置xml
    response = requests.get(f"{job_url}/config.xml", auth=("api_token", api_token))
    config_xml = ET.fromstring(response.content)

    # 更新配置xml中的内容
    # ...

    # 将更新后的配置xml发送回Jenkins服务器
    response = requests.post(f"{job_url}/config.xml", auth=("api_token", api_token), data=ET.tostring(config_xml))

    if response.status_code == 200:
        print(f"作业 {job_name} 的配置已成功更新")
    else:
        print(f"作业 {job_name} 的配置更新失败")
