These are my basic ASP Functions about regular expressions, very handy and powerful, for the Ancient ASP Technology.
List of Variables Representing Arguments
VStr, vStr2, vStr3 ….: the string
vPattern: the regular expression pattern, basic syntax at the bottom.
Function: Check Regular Expression Match
Function kCheckRegExp(vPattern, vStr)
Function: Replace String by Regular Expression
Replace vStr1 to vStr2 by vPattern
Function kLeachRegExp(vStr1, vPattern, vStr2)
Replace vStr1 to vStr2 by vPattern, only replace the first found match
Function kLeachRegExpOnce(vStr1, vPattern, vStr2)
Replace vStr1 to vStr2 by vPattern, only replace the first found match, and case-sensitive
Function kLeachRegExpOnceCase(vStr1, vPattern, vStr2)
oRegExp.IgnoreCase = False
Replace vStr1 to vStr2 by vPattern, case-sensitive
Function kLeachRegExpCase(vStr1, vPattern, vStr2)
oRegExp.IgnoreCase = False
Function: Find Matched String and Put into an Array
Function kMultiRegExp(vStr, vPattern)
Dim oRegExp, oMatches, vMatch, vArray, vStr2, vLoop
Set oMatches = oRegExp.Execute(vStr)
vArray = Array()
vLoop = -1
For Each vMatch in oMatches
Next
kMultiRegExp = vArray
| Character | Description |
| \ | Marks the next character as either a special character or a literal. For example, “n” matches the character “n”. “\n” matches a newline character. The sequence “\\” matches “\” and “\(” matches “(”. |
| ^ | Matches the beginning of input. |
| $ | Matches the end of input. |
| * | Matches the preceding character zero or more times. For example, “zo*” matches either “z” or “zoo”. |
| + | Matches the preceding character one or more times. For example, “zo+” matches “zoo” but not “z”. |
| ? | Matches the preceding character zero or one time. For example, “a?ve?” matches the “ve” in “never”. |
| . | Matches any single character except a newline character. |
| (pattern) | Matches pattern and remembers the match. The matched substring can be retrieved from the resulting Matches collection, using Item [0]…[n]. To match parentheses characters ( ), use “\(” or “\)”. |
| x|y | Matches either x or y. For example, “z|food” matches “z” or “food”. “(z|f)oo” matches “zoo” or “food”. |
| {n} | n is a nonnegative integer. Matches exactly n times. For example, “o{2}” does not match the “o” in “Bob,” but matches the first two o’s in “foooood”. |
| {n,} | n is a nonnegative integer. Matches at least n times. For example, “o{2,}” does not match the “o” in “Bob” and matches all the o’s in “foooood.” “o{1,}” is equivalent to “o+”. “o{0,}” is equivalent to “o*”. |
| {n,m} | m and n are nonnegative integers. Matches at least n and at most m times. For example, “o{1,3}” matches the first three o’s in “fooooood.” “o{0,1}” is equivalent to “o?”. |
| [xyz] | A character set. Matches any one of the enclosed characters. For example, “[abc]” matches the “a” in “plain”. |
| [^xyz] | A negative character set. Matches any character not enclosed. For example, “[^abc]” matches the “p” in “plain”. |
| [a-z] | A range of characters. Matches any character in the specified range. For example, “[a-z]” matches any lowercase alphabetic character in the range “a” through “z”. |
| [^m-z] | A negative range characters. Matches any character not in the specified range. For example, “[m-z]” matches any character not in the range “m” through “z”. |
| \b | Matches a word boundary, that is, the position between a word and a space. For example, “er\b” matches the “er” in “never” but not the “er” in “verb”. |
| \B | Matches a nonword boundary. “ea*r\B” matches the “ear” in “never early”. |
| \d | Matches a digit character. Equivalent to [0-9]. |
| \D | Matches a nondigit character. Equivalent to [^0-9]. |
| \f | Matches a form-feed character. |
| \n | Matches a newline character. |
| \r | Matches a carriage return character. |
| \s | Matches any white space including space, tab, form-feed, etc. Equivalent to “[ \f\n\r\t\v]“. |
| \S | Matches any nonwhite space character. Equivalent to “[^ \f\n\r\t\v]“. |
| \t | Matches a tab character. |
| \v | Matches a vertical tab character. |
| \w | Matches any word character including underscore. Equivalent to “[A-Za-z0-9_]“. |
| \W | Matches any nonword character. Equivalent to “[^A-Za-z0-9_]“. |
| \num | Matches num, where num is a positive integer. A reference back to remembered matches. For example, “(.)\1″ matches two consecutive identical characters. |
| \n | Matches n, where n is an octal escape value. Octal escape values must be 1, 2, or 3 digits long. For example, “\11″ and “11″ both match a tab character. “011″ is the equivalent of “01″ & “1″. Octal escape values must not exceed 256. If they do, only the first two digits comprise the expression. Allows ASCII codes to be used in regular expressions. |
| \xn | Matches n, where n is a hexadecimal escape value. Hexadecimal escape values must be exactly two digits long. For example, “\x41″ matches “A”. “\x041″ is equivalent to “\x04″ & “1″. Allows ASCII codes to be used in regular expressions. |
