从pyoai读取元数据结果

Question

我正在使用python3.7上的pyoai库使用oai-pmh协议获取元数据，但是在读取记录列表时遇到了麻烦

from oaipmh.client import Client
from oaipmh.metadata import MetadataRegistry, oai_dc_reader

URL = 'http://revista-iberoamericana.pitt.edu/ojs/index.php/Iberoamericana/oai'
registry = MetadataRegistry()
registry.registerReader('oai_dc', oai_dc_reader)
client = Client(URL, registry)

for record in client.listRecords(metadataPrefix='oai_dc'):
print(record)

我考虑了一种元组上的xml文件，但结果如下：

(<oaipmh.common.Header object at 0x00000251FAA16A20>, <oaipmh.common.Metadata object at 0x00000251FAA160B8>, None) 
(<oaipmh.common.Header object at 0x00000251FA9DB5C0>, <oaipmh.common.Metadata object at 0x00000251FA9C6518>, None) 
(<oaipmh.common.Header object at 0x00000251FA9DB0F0>, <oaipmh.common.Metadata object at 0x00000251FA9DB208>, None)

你能告诉我我忘了什么吗
