如何在一个文件中从所有HTTP响应中提取xml变量值

import xml.etree.ElementTree as ET

def extract_xml_variables_from_file(file_path):
    with open(file_path, 'r') as file:
        file_content = file.read()

    xml_variables = []
    http_responses = file_content.split('\n\n')  # 假设每个HTTP响应之间使用两个换行符分隔

    for response in http_responses:
        # 假设XML数据位于HTTP响应的正文部分
        xml_start_index = response.find('<')
        xml_end_index = response.rfind('>') + 1
        xml_data = response[xml_start_index:xml_end_index]

        # 解析XML数据
        root = ET.fromstring(xml_data)

        # 提取变量值
        variable_value = root.find('variable').text
        xml_variables.append(variable_value)

    return xml_variables

# 示例用法
file_path = 'http_responses.txt'
xml_variables = extract_xml_variables_from_file(file_path)
print(xml_variables)
