| regular character | describe |
|---|---|
| \ | Marks the next character as a special character, or a literal character, or a backward reference, or an octal escape character. For example, “N" match character "N"." n" Matches a newline character. Serial "\\"Match."\" and " ("Then match"(". |
| ^ | Matches the starting position of the input string. If the Multiline property of the RegExp object is set, ^ also matches “ n"Or" r" after that. |
| $ | Matches the end position of the input string. $also matches if the Multiline property of the RegExp object is set “ n"Or" r" previous location. |
| * | Matches the preceding subexpression zero or more times. For example, zo * can match “Z" and "zoo". * Equivalent to {0,}. |
| + | Matches the preceding subexpression one or more times. For example,“zo+"Can match"zo" and "zoo"But they don't match."Z".+ is equivalent to {1,}. |
| ? | Matches the preceding subexpression zero or once. For example,“do(es)?"Can match"does"Or"does"In"do".? Equivalent to {0,1}. |
| {N) | N Is a non-negative integer. Match determined NTimes. For example, "o{2)" Can't match "Bob"In"o" but can match "Food"two o. |
| {N,} | N Is a non-negative integer. Matches at least NTimes. For example, "o{2,}" can't match "Bob"In"o" but can match "foooood" all o."O {1,}"Equivalent to"O +"."O {0,}"Is equivalent to"O *". |
| {N,m) | mandNBoth are non-negative integers, whereN< =mLeast matchNsecond and most matchesmTimes. For example, "O {1,3)"Will match"FOOOOD"The first three o's in."O {0, 1)"Equivalent to"O?". Please note that there can be no spaces between commas and two numbers." |
| ? | When the character immediately follows any other restrictor （*,+,?，{N}, {N,}, {N,m}) Later, the matching pattern is non-greedy. The non-greedy pattern matches as few strings as possible, while the default greedy pattern matches as many strings as possible. For example, for string "Oooo","O +?"Will match a single"o"And"O +"Will match all"o". |
| . | Match except "\NAny single character other than ". To match include"\N"Any character included, please use something like"(. | n)"The model. |
| (Pattern) | Matches the pattern and gets the match. The obtained match can be obtained from the resulting Matches collection, using the SubMatches collection in VBScript and the 0 dollars... 9 dollars attribute in JScript. To match parenthesis characters, use " ("Or")". |
| (?: pattern) | Matches the pattern but does not fetch the match result, that is, it is a non-fetch match and is not stored for later use. This is used in the or character "(|)"It is useful to combine parts of a pattern. For example"industr (?: y | ies)"Just a comparison"Industries | industries"A more abbreviated expression." |
| (? = pattern) | Positive presearch matches the lookup string at the beginning of the string of any matching pattern. This is a non-fetching match, that is, the match does not need to be fetched for later use. For example, "Windows (? = 95 | 98 | NT | 2000)"Can match"Windows 2000"In"Windows"But they don't match."Windows 3.1"In"Windows". Pre-search does not consume characters, that is, after a match occurs, the search for the next match begins immediately after the last match, rather than after the character containing the pre-ການຊອກຫາ. |

For example "Windows (?! 95 | 98 | NT | 2000)"Can match"Windows 3.1"In"Windows"But they don't match."Windows 2000"In"Windows". Pre-search does not consume characters, that is, after a match occurs, the search for the next match starts immediately after the last match, rather than starting after the character containing the pre-search |
| (? < = pattern) | A reverse positive precheck is analogous to a forward positive precheck, but in the opposite direction. For example, "(? < = 95 | 98 | NT | 2000) Windows"Can match"2000Windows"In"Windows"But they don't match."3.1 Windows"In"Windows". |
| (? <! pattern) | A reverse negative precheck is analogous to a forward negative precheck, but in the opposite direction. For example "(? <! 95 | 98 | NT | 2000) Windows"Can match"3.1 Windows"In"Windows"But they don't match."2000Windows"In"Windows". |
| X | y | Matches x or y. For example, "Z | food"Can match"Z"Or"Food"."(Z | f) ood"Then match"Zood"Or"Food". |
| [Xyz] | Character set. Matches any character contained. For example, "[Abc]"Can match"plain"In"A". |
| [^ xyz] | Set of negative characters. Matches any character not contained. For example, "[^ abc]"Can match"plain"In"p". |
| [A-z] | Character range. Matches any character within the specified range. For example, "[A-z]"Can match"A"To."Z"Any lowercase alphabetic character in the range. |
| ^[ a-z] | Negative character range. Matches any character that is not within the specified range. For example, "^[ a-z]"Can match anything that is not there"A"To."Z"Any character in the range. |
