Only the highest level parentheses are used. For example, if the search
pattern and(y|rew) finds the text andrew, token 1 is assigned the value rew.
However, if the search pattern (and(y|rew)) is used, token 1 is assigned
the value andrew.
UsingTokens—Example2
Use (expr) and \N to capture pairs of matching HTML tags (e.g., and
) and the text between them. The expression used for this example is
expr = '.*?';
The first part of the expression, ’), and any characters that may precede the
next opening bracket.
The last part, '', matches all characters in the ending HTML tag. This
tag is composed of the sequence , wheretag is whatever characters
were captured as a token.
hstr = 'Default';
expr = '.*?';
[mat tok] = regexp(hstr, expr, 'match', 'tokens');
