在匹配模式之前獲得單個匹配嗎？

我有一個像下面在匹配模式之前獲得單個匹配嗎？

{"id":9,"announcementName":"Test","announcementText":"<p>TestAssertion</p>\n","effectiveStartDate":"03/01/2016","effectiveEndDate":"03/02/2016","updatedDate":"02/29/2016","status":"Active","moduleName":"Individual Portal"} 
{"id":103,"announcementName":"d3mgcwtqhdu8003","announcementText":"<p>This announcement is a test announcement」,"effectiveStartDate":"03/01/2016","effectiveEndDate":"03/02/2016","updatedDate":"02/29/2016","status":"Active","moduleName":"Individual Portal"} 
{"id":113,"announcementName":"asdfrtwju3f5gh7f21","announcementText":"<p>This announcement is a test announcement」,"effectiveStartDate":"03/02/2016","effectiveEndDate":"03/03/2016","updatedDate":"02/29/2016","status":"InActive","moduleName":"Individual Portal"}

我試圖讓announcementName d3mgcwtqhdu8003的ID（103）的值的響應。

我使用下面的正則表達式來獲取ID

"id":(.*?),"announcementName":"${announcementName}","announcementText":"

但它匹配一切從第一證件到announcementName。並返回

9,"announcementName":"Test","announcementText":"<p>TestAssertion</p>\n","effectiveStartDate":"03/01/2016","effectiveEndDate":"03/02/2016","updatedDate":"02/29/2016","status":"Active","moduleName":"Individual Portal"} 
{"id":103,"announcementName":"d3mgcwtqhdu8003","announcementText":

但我想只從ID 只是所需announcementName之前匹配。

如何在RegEx中執行此操作。有人可以幫助我嗎？

ps：無法爲此構建正確的問題標題。： -/ –

你可以添加一個特定的語言標籤嗎？（javascript ??） –

是不是這個'JSON'？爲什麼你不使用適當的解析器？如果不是，這些ID是數字的，就像'「id」一樣簡單：（\ d +）'[可能會這樣做]（https://regex101.com/r/iQ5jL0/1）。 – Jan

作爲一個答案在這裏。無論是使用適當的JSON功能，如果沒有，一個簡單的正則表達式，如：

"id":(\d+)

will probably do的ID是數字。
