1260 =item Simple word matching

1264 \d is a digit and represents [0-9], \s is a whitespace character and
1265 represents [\ \t\r\n\f], \w is a word character (alphanumeric or _) and
1266 represents [0-9a-zA-Z_], \D is a negated \d; it represents any character
1267 but a digit [^0-9], \S is a negated \s; it represents any non-whitespace
1268 character [^\s], \W is a negated \w; it represents any non-word character
1269 [^\w], The period '.' matches any character but "\n", no modifiers (//):
1270 Default behavior. C<'.'> matches any character except C<"\n">. C<^>
1271 matches only at the beginning of the string and C<$> matches only at the
1272 end or before a newline at the end, s modifier (//s): Treat string as a
1273 single long line. C<'.'> matches any character, even C<"\n">. C<^>
1274 matches only at the beginning of the string and C<$> matches only at the
1275 end or before a newline at the end, m modifier (//m): Treat string as a set
1276 of multiple lines. C<'.'> matches any character except C<"\n">. C<^> and
1277 C<$> are able to match at the start or end of I<any> line within the
1278 string, both s and m modifiers (//sm): Treat string as a single long line,
1279 but detect multiple lines. C<'.'> matches any character, even C<"\n">.
1280 C<^> and C<$>, however, are able to match at the start or end of I<any>
1281 line within the string
1283 =item Matching this or that
1285 =item Grouping things and hierarchical matching
1287 0 Start with the first letter in the string 'a', 1 Try the first
1288 alternative in the first group 'abd', 2 Match 'a' followed by 'b'. So far
1289 so good, 3 'd' in the regexp doesn't match 'c' in the string - a dead end.
1290 So backtrack two characters and pick the second alternative in the first
1291 group 'abc', 4 Match 'a' followed by 'b' followed by 'c'. We are on a roll
1292 and have satisfied the first group. Set $1 to 'abc', 5 Move on to the
1293 second group and pick the first alternative 'df', 6 Match the 'd', 7 'f' in
1294 the regexp doesn't match 'e' in the string, so a dead end. Backtrack one
1295 character and pick the second alternative in the second group 'd', 8 'd'
1296 matches. The second grouping is satisfied, so set $2 to 'd', 9 We are at
1297 the end of the regexp, so we are done! We have matched 'abcd' out of the
1300 =item Extracting matches
1302 =item Matching repetitions
1304 C<a?> = match 'a' 1 or 0 times, C<a*> = match 'a' 0 or more times, i.e.,
1305 any number of times, C<a+> = match 'a' 1 or more times, i.e., at least
1306 once, C<a{n,m}> = match at least C<n> times, but not more than C<m> times,
1307 C<a{n,}> = match at least C<n> or more times, C<a{n}> = match exactly C<n>
1308 times, Principle 0: Taken as a whole, any regexp will be matched at the
1309 earliest possible position in the string, Principle 1: In an alternation
1310 C<a|b|c...>, the leftmost alternative that allows a match for the whole
1311 regexp will be the one used, Principle 2: The maximal matching quantifiers
1312 C<?>, C<*>, C<+> and C<{n,m}> will in general match as much of the string
1313 as possible while still allowing the whole regexp to match, Principle 3: If
1314 there are two or more elements in a regexp, the leftmost greedy quantifier,
1315 if any, will match as much of the string as possible while still allowing
1316 the whole regexp to match. The next leftmost greedy quantifier, if any,
1317 will try to match as much of the string remaining available to it as
1318 possible, while still allowing the whole regexp to match. And so on, until
1319 all the regexp elements are satisfied, C<a??> = match 'a' 0 or 1 times. Try
1320 0 first, then 1, C<a*?> = match 'a' 0 or more times, i.e., any number of
1321 times, but as few times as possible, C<a+?> = match 'a' 1 or more times,
1322 i.e., at least once, but as few times as possible, C<a{n,m}?> = match at
1323 least C<n> times, not more than C<m> times, as few times as possible,
1324 C<a{n,}?> = match at least C<n> times, but as few times as possible,
1325 C<a{n}?> = match exactly C<n> times. Because we match exactly C<n> times,
1326 C<a{n}?> is equivalent to C<a{n}> and is just there for notational
1327 consistency, Principle 3: If there are two or more elements in a regexp,
1328 the leftmost greedy (non-greedy) quantifier, if any, will match as much
1329 (little) of the string as possible while still allowing the whole regexp to
1330 match. The next leftmost greedy (non-greedy) quantifier, if any, will try
1331 to match as much (little) of the string remaining available to it as
1332 possible, while still allowing the whole regexp to match. And so on, until
1333 all the regexp elements are satisfied, 0 Start with the first letter in the
1334 string 't', 1 The first quantifier '.*' starts out by matching the whole
1335 string 'the cat in the hat', 2 'a' in the regexp element 'at' doesn't match
1336 the end of the string. Backtrack one character, 3 'a' in the regexp
1337 element 'at' still doesn't match the last letter of the string 't', so
1338 backtrack one more character, 4 Now we can match the 'a' and the 't', 5
1339 Move on to the third element '.*'. Since we are at the end of the string
1340 and '.*' can match 0 times, assign it the empty string, 6 We are done!
