From numbers we’ll move to alphabets first an example for validation lowercase alphabets and then to validate both uppercase and lowercase.
Here we create a Reg Exp pattern and use the match to validate it.
A regular expression could be defined with the Reg Exp () constructor, as follows − The ranges shown above are general; you could also use the range [0-3] to match any decimal digit ranging from 0 through 3, or the range [b-v] to match any lowercase character ranging from b through v. For instance, you can search for a large sum of money using the '\d' metacharacter: /([\d] )000/, Here \d will search for any string of numerical character.
The frequency or position of bracketed character sequences and single characters can be denoted by a special character. The following table lists a set of metacharacters which can be used in PERL Style Regular Expressions.
