Question

我目前正在处理一个脚本，该脚本从我们的Cisco Prime基础设施中获取网络设备的完整列表，然后将这些设备添加到我们的Cisco ISE安装中。

Cisco Prime基础设施的输出数据超过25000行，为文本。

示例输出：

现在，我只想将以 entity 开始并以 / entity 结尾的行保存到列表中，并且每个部分都应该是其自己的列表。

示例：

[['<entity dtoType="devicesDTO" type="Devices" url="https://X.X.X.X/webacs/api/v4/data/Devices/7860155308">', '...truncated...', '</entity>'], ['<entity dtoType="devicesDTO" type="Devices" url="https://X.X.X.X/webacs/api/v4/data/Devices/7605631035">', '...truncated...', '</entity>']]

我当前的代码：

#!/usr/bin/python
# coding=utf-8
import sys
import requests
import xml.etree.ElementTree as ET

response = requests.get('https://X.X.X.X/webacs/api/v4/data/Devices?.full=true&.sort=deviceName', verify=False)
output = response.text

data = []

for line in output:
    data.append(line)

但是它给出了奇怪的结果。我无法理解当前如何解决这个问题。一些帮助，将不胜感激。

编辑：

我可以看到每行末尾都有一个 \ n 。如果我这样做：

output = output.split("\n")

我得到一个包含所有数据的列表。

您可以采取两种方法：

第一种方法：逐行

如果要逐行运行代码，可以使用regex检查行是否符合要求：

for line in output:
    if re.match(r'entity.*/entity', line):
        print("It's a match")

这将与您拥有“任何文本（例如<）实体任何文本 / entity 任何文本（例如>）”的每一行匹配但是，这只会捕获单行实体。另外，您可以查找带有开始标签和开始标签的行，并在以下两者之间捕获内容：

for line in output:
    if re.match(r'entity', line):
        if re.match(r'/entity', line):
            print("End of block")
        else:
            print("Start of block")

第二种方法：XML

如果您想将其实际视为XML，不仅可以查找单行 entity 对象，还可以使用xml.etree.ElementTree并按照here的描述运行递归findall。查找每个实体元素。

将REST API中的特定部分保存到列表中
