Method ExtString.RxSplit

---

Overload

Returns an array of substrings that in this string are delimited by regular expression matches.

public static string[] RxSplit(this string t, string rx, int maxCount = 0, RXFlags flags = 0, Range? range = null)

Parameters

t  (string) This string.

rx  (string) Regular expression. Cannot be null.

maxCount  (int) Maximal count of substrings to get. The last substring contains the unsplit remainder of the subject string. If 0 (default) or negative, gets all.

flags  (RXFlags) Options. Default 0. Flag UTF is implicitly added if rx contains non-ASCII characters and there is no flag NEVER_UTF.

range  (Range?) Start and end offsets in the subject string. If null (default), uses whole string. Examples: i..j (from i to j), i.. (from i to the end), ..j (from 0 to j). The subject part before the start index is not ignored if regular expression starts with a lookbehind assertion or anchor, eg ^ or \b or (?<=...). Instead of ^ you can use \G or flag RXFlags.ANCHORED. More info in PCRE documentation topic pcre2api, chapter "The string to be matched by pcre2_match()". The subject part after the end index is always ignored.

Returns

string[]
