Introdução às expressões regulares:
1. Expressões regulares (Regular Expression, abreviadas como Regex ou RE) são um tipo de padrão utilizado para corresponder combinações de caracteres em cadeias de caracteres.
2. As expressões regulares têm origem nos campos da teoria e da ciência da computação e são hoje amplamente utilizadas em diversas linguagens de programação e ferramentas de processamento de texto para pesquisar, substituir, validar e analisar textos.
3. Os componentes básicos das expressões regulares incluem:
(1) Correspondência de caracteres: corresponde a caracteres específicos, como letras, números ou símbolos. Exemplo: a corresponde ao caractere ‘a’.
(2) Metacaracteres: caracteres com significado especial, usados para representar um determinado padrão. Exemplo: . corresponde a qualquer caractere único (exceto o caractere de quebra de linha); * indica que o caractere anterior pode aparecer zero ou mais vezes.
(3) Conjunto de caracteres: representado por colchetes [], corresponde a qualquer um dos caracteres nele contidos; por exemplo: [abc] corresponde a ‘a’, ‘b’ ou ‘c’.
(4) Repetição: especifica quantas vezes o elemento anterior pode ser repetido; por exemplo: a{3} corresponde a ‘aaa’; a{2,4} corresponde a ‘aa’, ‘aaa’ ou ‘aaaa’.
(5) Ramificação: representada pelo símbolo de barra vertical |, indica a relação “ou”. Exemplo: a|b corresponde a ‘a’ ou ‘b’.
(6) Agrupamento: representado por parênteses () permite combinar vários elementos em uma única unidade; por exemplo: (ab) trata ‘ab’ como um todo.
(7) Âncoras: usadas para especificar a posição da correspondência. Exemplo: ^ indica o início da string; $ indica o fim da string.
