获取 cdata

 with open(file_name, 'r') as f:
        xml_string = f.read()
    import xml.etree.ElementTree as ET
    root = ET.fromstring(xml_string)
    for c_data  in root.findall(".//logging_string"):
        data_content =  c_data.text.replace("<![CDATA[", "").replace("]]>", "")
        print(data_content)
