I have the following text = "superilustrado e de capa dura?", and I want to find all the spaces between words in the text. I am using the following expression = [\\p{L}[:punct:]][[:space:]][\\p{L}[:punct:]]. The expression works fine but it can find the space between the "e de". Does anybody know what is the problem with my regular expression?
Answer
Spaces can be found simply by putting a space character in your regex.
Whitespace can be found with \s.
If you want to find whitespace between words, use the \b word boundary marker.
This would match a single space between two words:
"\b \b"
(The reason your match failed is that \\p{L} includes the character in a match. Because e is only one character, it gets eaten up by the previous match and can't be matched for the space after e. \b avoids this problem because it is a zero-width match.)
