如何在Java中使用转义的“ \\”从json数据中提取url

Question

I need to extract url from json filed. (replace it with "" and do not break the json format), so that there's no url in json.

the url looks in this way

"source":"\u003ca href=\"http:\/\/twitter.com\/download\/iphone\",
"profile_image_url_https":"https:\/\/pbs.twimg.com\/profile_images\/3475536942\/2b0ccd9e42754adf7e22947037dd8c34_normal.jpeg","profile_banner_url":"https:\/\/pbs.twimg.com\/profile_banners\/488849893\/1364691799",

...

I noticed that there's "\\" in the url to escape the string, I don't know how to deal with it while writing the regex.

Simply use a lightweight JSON parser such as this reference implementation in Java

To overwrite, say, the source property to "blah", it is possible to do things as simple as

String newJsonString = new JSONObject(originalJsonString).putString("source","blah").toString();
