Examples with RE org.apache.regexp.RE used on opensource projects

Example 1 with RE

use of org.apache.regexp.RE in project ant by apache.

the class JakartaRegexpMatcher method getGroups.

/**
 * Returns a Vector of matched groups found in the argument.
 *
 * <p>Group 0 will be the full match, the rest are the
 * parenthesized subexpressions</p>.
 *
 * @param input the string to match against
 * @param options the regex options to use
 * @return the vector of groups
 * @throws BuildException on error
 */

    }
    Vector<String> v = new Vector<>();
    int cnt = reg.getParenCount();
    for (int i = 0; i < cnt; i++) {
        String match = reg.getParen(i);
        // treat non-matching groups as empty matches

            match = "";
        }
        v.add(match);

Example 3 with RE

use of org.apache.regexp.RE in project ant by apache.
