如何从改变元素的JSONL文件中提取元素？

import json

def extract_elements_from_jsonl(jsonl_file):
    extracted_elements = []
    
    with open(jsonl_file, 'r') as file:
        for line in file:
            json_obj = json.loads(line)
            
            # 提取元素的示例逻辑
            element = json_obj['element_key']
            
            extracted_elements.append(element)
    
    return extracted_elements

# 调用函数并传入JSONL文件路径
jsonl_file = 'path/to/jsonl_file.jsonl'
elements = extract_elements_from_jsonl(jsonl_file)

# 打印提取到的元素
for element in elements:
    print(element)
