如何遍历多文档YAML文件以通过管道传递到一个命令？

import yaml
import sys

def process_yaml_file(file_path):
    with open(file_path, 'r') as file:
        yaml_data = yaml.safe_load_all(file)
        for document in yaml_data:
            # 在这里对每个文档执行你的操作
            # 例如，打印文档内容
            print(document)

if __name__ == "__main__":
    file_path = sys.argv[1]
    process_yaml_file(file_path)

python yaml_parser.py data.yaml
