您想要搜索此对象数组。此对象可以具有带对象数组的childrean。这些很难找到找到对象的逻辑。我试过了。
import re
s = '''
{
title = "Hello",
description = 9,
followup = [
{
title = "World",
description = 0,
}
]
}'''
s = re.sub(r'(\s+\d+),', r'\1', s)
print(s)
这仅在第一层中显示。我想看看整个对象。 有人有个主意吗？也许有一个简单的解决方案？ 示例对象：
let obj = DATA.children.find(o => o.size === 4461)
