Example text

To match a pattern starting from the beginning, you must use the carat symbol (^) or the special character \A (backslash-capital “A”). The latter is primarily for keyboards that do not have the carat symbol (for instance, an international keyboard). Similarly, the dollar sign ($) or \Z will match a pattern from the end of a string. Patterns that use these symbols differ from most of the others we describe in this chapter because they dictate location or position. In the previous Core Note, we noted that a distinction is made between matching (attempting matches of entire strings starting at the beginning) and searching (attempting matches from anywhere within a string).

These subgroups can be recalled for the same match or search, or extracted for post-processing. 9. Why are matches of subgroups important? The main reason is that there are times when you want to extract the patterns you match, in addition to making a match. For example, what if we decided to match the pattern \w+-\d+ but wanted save the alphabetic first part and the numeric second part individually? We might want to do this because with any successful match, we might want to see just what those strings were that matched our regex patterns.

We will be using almost all of the special characters and symbols that are part of the regular expression syntax. 2, we used the pipe character in the regex bat|bet|bit. group() ... group() ... group() ... group() ... group() ... group() ... group() ... group() ... group() ... group() ... group() ... 14' # regex dot # literal dot (dec. group() ... group() ... group() ... group() ... 9 Repetition, Special Characters, and Grouping The most common aspects of regexes involve the use of special characters, multiple occurrences of regex patterns, and using parentheses to group and extract submatch patterns.
