life is more interesting if you can step outside of your own world every once in a while.

The joy of nonfiction is searching for balance between storytelling and reporting, finding a way to be both loquacious and observant.

“Russian women get fat because they don’t care,”
上面是 My Clipping.txt 的一个片段，每段 highlights，以==========分割，包括书籍，作者，位置，时间，内容等信息，我想把这文件 parse 成包含以下结构 Hash 的 Array：
{
book: 'Strange Stones: Dispatches from East and West',
author: 'Hessler, Peter',
location: '1306-1306',
time: DateTime.parse('Saturday, August 17, 2013 1:50:31 PM'),
content: 'Russian women get fat because they don’t care.'
}
请大家提供一个思路，谢谢。
def parse(clippings)
rule = Regexp.new /\n?(?<book>.*) \(P\.S\.\) \((?<author>.*)\)\n.*Location (?<location>\d+-\d+) \|.*on (?<date>.*)\n*(?<content>.*)\n?/
clippings.split('==========').map do |c|
m = c.match rule
{book: m[:book], author: m[:author], location: m[:location], date: DateTime.parse(m[:date]), content: m[:content] }
end
end
