作者文件的结构如下：
/type/author /authors/OL100223A 2 2008-09-08T16:20:28.105165 {"name": "Umu Hilmy", "personal_name": "Umu Hilmy", "last_modified": {"type": "/type/datetime", "value": "2008-09-08T16:20:28.105165"}, "key": "/authors/OL100223A", "type": {"key": "/type/author"}, "revision": 2}
/type/author /authors/OL6606949A 1 2009-05-14T08:13:43.294872 {"name": "Elizabeth Edwards", "created": {"type": "/type/datetime", "value": "2009-05-14T08:13:43.294872"}, "personal_name": "Elizabeth Edwards", "last_modified": {"type": "/type/datetime", "value": "2009-05-14T08:13:43.294872"}, "latest_revision": 1, "key": "/authors/OL6606949A", "birth_date": "1949", "type": {"key": "/type/author"}, "revision": 1}

我最终想要的是一个制表符分隔的文件，其中只包含以下信息：
OL参考标题名称isbn_10 isbn_13 subject subject_places subject_people
例如：
/ books / OL24712550M拯救美国人Elizabeth Edwards 0786291672 9780786291670＆＃34;巨蟹座＆＃34;，＆＃34;家庭＆＃34;，＆＃34;立法者＆＃39;配偶＆＃34;，＆＃34;哲学＆＃34;，＆＃34;患者＆＃34;，＆＃34;大型书籍＆＃34;，＆＃34;律师＆＃39;配偶＆＃34;，＆＃34;传记＆＃34;，＆＃34;受保护的DAISY＆＃34; ＆＃34;美国＆＃34;，＆＃34;北卡罗来纳州＆＃34; ＆＃34; Elizabeth Edwards（1949 - ）＆＃34;，＆＃34; John Edwards（1953年6月10日 - ）＆＃34;
（在某些情况下，其中一些字段将为空。）
因此，除了名称＆＃39;来自作者转储的字段，通过版本转储中的引用查找，例如/ authors / OL6606949A。
所以我试图将JQ用于以下查询（仅用于测试几列）：
.personal_name as $ names | .authors | {title，name，author：$ names [.key]}
但它甚至没有执行，因为我也在找到作者密钥的表示法时遇到问题。
答案 0 :(得分：1)
由于主题等可以有多个值，您希望它们如何在输出中分开，以免模糊不清？
jq '.personal_name as $names | .authors as $authors| {title, name, author: $names[.key]}'
是您在问题中使用的jq命令的固定版本，但未使用$authors。
无论如何，如果你澄清了你的意思，我们肯定可以做到这一点！
