Objective-C/Swift regex matching across multliple lines

Question

I have a regular expression originally used in python to extract 2 strings from a scraped HTML page : var\\s+kaynaklar.*?url\\s*:\\s*\\\"([^\\\"]+)\\\"\\s*,\\s*data\\s

Answer 1

From your feedback, I see you just need to tell the regex engine to match a newline with a period.

Use the NSRegularExpressionOptions.DotMatchesLineSeparators option:

Allow . to match any character, including line separators.


Available in OS X v10.7 and later.

As a quicker-to-implement alternative, use an inline (?s) modifier at the beginning of the pattern:

let regexString = "(?s)var\\s+kaynaklar.*?url\\s*:\\s*\\\"([^\\\"]+)\\\"\\s*,\\s*data\\s*:\\s*'([^']+)"

See the regex demo.
