c# - 正则表达式：获取 url 和标题形式的 json 字符串

Question

我有很多 Firefox 会话管理器保存的文件，名为 *.session.and 我想从文件中导出 url 和标题，我写了正则表达式：

(?<=entries":\[{"url":"(?<link>.*?(?="))","title":"(?<content>.*?)(?=",")) 

但似乎效果不佳。它匹配得太多了。

Answer 1

为什么不解析 json 并在不使用正则表达式的情况下循环呢？

Answer 2

马特布莱恩特的方式似乎是最好的。对于您的正则表达式问题，您可以简单地使用：

"url":"(?<link>[^"]+)","title":"(?<content>[^"]+)

或为了更安全

"url":"(?<link>(?>[^"]+|(?<=\\)")+)","title":"(?<content>(?>[^"]+|(?<=\\)")+)
