正規語法 (Regular Grammar) 是一種相當簡單的語法,這種語法被 Perl 語言成功的用於字串比對,接著成為重要的程式設計工具。此種標準的正規語法後來被稱為正則表達式 (Regular Expression)。目前,大部分的語言都已納入正則表達式的函式庫,正則表達是可以說是程式設計師必定要瞭解的工具,也就是常識的一部分。系統程式...

regular expression syntax provides a powerful tool for pattern matching in strings. regular expressions (regex) use a combination of characters and special symbols to define patterns that match specific sequences of characters. for example, the regex pattern "^[a-za-z]+$" matches strings ...

Alternatively, you can use the setPatternOptions() function on an existing QRegularExpressionObject: QRegularExpression re("^\\d+$"); re.setPatternOptions(QRegularExpression::MultilineOption); // re matches any line in the subject string that contains only digits (but at least one) It is ...
Regular expressions can be concatenated to form new regular expressions; if A and B are both regular expressions, then AB is also a regular expression. In general, if a string p matches A and another string q matches B, the string pq will match AB. This holds unless A or B contain low...
