如何解析定义了多个命名空间soap xml响应。我需要解析返回的文章数组

import xml.etree.ElementTree as ET

# 假设SOAP XML响应存储在response变量中
response = """
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/namespace1" xmlns:ns2="http://example.com/namespace2">
    <soap:Body>
        <ns1:Response>
            <ns2:Articles>
                <ns2:Article>
                    <ns2:Title>Article 1</ns2:Title>
                    <ns2:Content>Content 1</ns2:Content>
                </ns2:Article>
                <ns2:Article>
                    <ns2:Title>Article 2</ns2:Title>
                    <ns2:Content>Content 2</ns2:Content>
                </ns2:Article>
            </ns2:Articles>
        </ns1:Response>
    </soap:Body>
</soap:Envelope>
"""

# 解析SOAP XML响应
root = ET.fromstring(response)

# 定义命名空间映射
namespaces = {
    'soap': 'http://schemas.xmlsoap.org/soap/envelope/',
    'ns1': 'http://example.com/namespace1',
    'ns2': 'http://example.com/namespace2'
}

# 提取文章数组
articles = []
article_elements = root.findall('.//ns2:Article', namespaces)
for article_element in article_elements:
    title = article_element.find('ns2:Title', namespaces).text
    content = article_element.find('ns2:Content', namespaces).text
    article = {
        'Title': title,
        'Content': content
    }
    articles.append(article)

# 打印文章数组
for article in articles:
    print(article)
