Here are some regular expressions that may be encountered: Visual Basic VBScript Match Scripting Edition / ^ / [/ T * $ / "^ / [/ t] * $" matches a blank line. // D {2} - / d {5} / "/ d {2} - / d {5}" verifies whether an ID number consists of a 2-bit word, a hyphen, and a 5-digit. /< (.*)>. (*)>. * "matches an HTML tag. The following table is a full list of metammatics and its behavior in the regular expression context: Character Description / Tags the next character as a special character, or a primary character, or a backward reference, or an octal escape symbol. For example, 'n' matches characters "n". '/ N' matches a newline. Sequence '//' match "/" "/ (" matches "(". ^ Match the input string of the start position. If the multiline property of the regexp object is set, ^ also matches '/ n' or '/ r' The next location. $ Match the end position of the input string. If the multiline property of the regexp object is set, $ also matches the position before '/ n' or '/ r'. * Match the previous sub-expression zero or multiple times For example, ZO * can match "z" and "zoo". * Equivalent to {0,}. Match the previous sub-expression once or more. For example, 'ZO ' can match "ZO" and "ZOO" However, it cannot match "Z". Equivalent to {1,}. • Match the previous sub-expression zero or once. For example, "Do (es)" can match "do" or "does" "" " Do ".? Is equivalent to {0,1}. {n} n is a non-negative integer. Match the N times. For example, 'o {2}' does not match" Bob "'o', but can Match two O. {n,} n is a non-negative integer. At least n times. For example, 'o {2,}' does not match 'O' in "Bob", but can match " All O.'o {1,} 'in fooood is equivalent to' o '.' o {0,} 'is equivalent to' o * '. {n, m} M and N are non-negative integers Where n <= m. Minimize n times and matched M times. Liu, "O {1, 3}" will match the top three of "foooood" in the "foooood". 'O {0, 1}' is equivalent to 'o?'. Please note that there is no space between commas and two numbers? When the character is tight in any other restriction (*, ,?, {n}, {n,}, {n, m When the matching mode is not greedy. The default greed mode matches the search string as possible without greed mode, and the default greed mode is as many as possible. For example, for the string "oooo" , 'O ?' Will match a single "O", and 'o ' will match all 'o'. Match any individual characters other than "/ n". To match any character, including '/ n', Please use the mode of '[./n]'. (Pattern) Match Pattern and get this match. The acquired match can be obtained from the generated Matches collection, using the Submatches collection in VBScript, in Visual Basic Scripting Edition Use $ 0 ... $ 9 attribute.
To match the bracket characters, use '/ (' or '/)'. (?: pattern) Match Pattern but does not acquire matching results, that is, this is a non-acquired match, not for storage. This is useful to use the "or" character (|) to combine a pattern. For example, 'industr (?: Y | iES) is a smale of' Industry | Industries'. (? = pattern) Positive to check, match the lookup string at any string of Pattern. This is a non-acquisition match, that is, the match does not need to be used later. For example, 'Windows (? = 95 | 98 | NT | 2000) can match "Windows" in "Windows 2000", but cannot match "Windows" in "Windows3 .1". The forecast does not consume characters, that is, after a match occurs, start the next matching search immediately after the last match, not starting from the character containing the pre-check. (?! pattern) negotiation, match the lookup string at any string of any mismatch at any Point WHERE A STRING NOT MATCHING POINT WHERE A STRING NOT MATCHING PATTERN. This is a non-acquired match, that is, the match does not need to be used later. For example, 'Windows (?! 95 | 98 | NT | 2000) "can match" Windows "in Windows 3.1, but cannot match" Windows "in" Windows 2000 ". The forecast does not consume characters, that is, after a match occurs, immediately start the next matching search immediately after the last match, instead of the X | Y, the X | Y is matched after the queue containing the pre-examined character. For example, 'Z | Food' can match "z" or "food". '(Z | f) OOD' matches "Zood" or "Food". [XYZ] Character collection. Match any of the included characters. For example, '[abc]' can match 'a' in "Plain". [^ XYZ] Negative character set. Match any of the characters that are not included. For example, '[^ ABC]' can match 'P' in "Plain". [A-Z] character range. Match any of the characters within the specified range. For example, '[a-z]' can match any lowercase letters character in the 'A' to 'Z' range. [^ a-z] Negative character range. Match any of any characters that are not within the specified range. For example, '[^ a-z]' can match any of any characters that are not in the 'A' to 'Z'. / b Match a word boundary, that is, the location of the words and spaces. For example, 'er / b' can match 'ER' in "Never", but do not match 'Er' in "Verb". / B matches non-word boundary. 'ER / B' Match 'Er' in "Verb", but does not match 'Er' in "Never". / CX matches the control character indicated by x. For example, / cm matches a Control-M or a carrier. The value of x must be one of A-Z or A-Z. Otherwise, the C is treated as a protact 'c' character. / d Match a numeric character. Equivalent to [0-9]. / D Match a non-digital character. Equivalent to [^ 0-9]. / f Match a change page. Equivalent to / x0c and / cl.
/ n Match a newline. Equivalent to / x0a and / cj. / r Match a carriage return. Equivalent to / X0D and / cm. / s Match any blank character, including spaces, tabs, change page, and the like. Equivalent to [/ f / n / r / t / v]. / S Match any non-blank character. Equivalent to [^ / f / N / R / T / V]. / t matches a tab. Equivalent to / x09 and / ci. / v Match a vertical tab. Equivalent to / x0b and / ck. / w Match any word character that includes underscore. Equivalent to '[A-ZA-Z0-9_]'. / W Match any non-word characters. Equivalent to '[^ a-za-z0-9_]'. / XN matches n, where n is a hexadecimal escape value. The hexadecimal escape value must be a long two numbers. For example, '/ x41' matches "a". '/ X041' is equivalent to '/ x04' & "1". ASCII coding can be used in regular expressions. . / NUM matches NUM, where NUM is a positive integer. References to the acquired match. For example, '(.) / 1' matches two consecutive identical characters. / n identifies an octal escape value or a rearward reference. If the sub-expression of at least N before / N, n is a backward reference. Otherwise, if n is an octal number (0-7), then n is an eight-input escape value.
