有没有办法用Xpath访问CDATA中的XML元素？

from lxml import etree

# 加载XML文档
xml_data = '''
<root>
    <data><![CDATA[<person>
        <name>John</name>
        <age>30</age>
    </person>]]></data>
</root>
'''
root = etree.fromstring(xml_data)

# 定位CDATA节点
cdata_node = root.find('data')

# 提取CDATA内容
cdata_content = cdata_node.text

# 解析CDATA内容
cdata_root = etree.fromstring(cdata_content)

# 使用XPath访问XML元素
name_element = cdata_root.find('name')
age_element = cdata_root.find('age')

# 打印结果
print(name_element.text)  # 输出：John
print(age_element.text)  # 输出：30
