Daftar Ekspresi Reguler

Istilah

Representasi/Gunakan

Karakter

The given character unless it is a regular expression meta character, which follow in this table.

.

Setiap karakter tunggal kecuali satu baris atau paragraf. Misalnya, istilah pencarian "sh.rt" sesuai dengan "shirt" dan "short".

^

Awal paragraf atau sel. Objek khusus seperti bidang kosong atau bingkai karakter-berlabuh, diawal paragraf diabaikan. Misalnya: "^Peter" sesuai dengan kata "Peter" hanya ketika itu adalah kata pertama dari sebuah paragraf.

$

Akhir paragraf atau sel. Objek khusus seperti bidang kosong atau bingkai karakter-berlabuh di akhir paragraf diabaikan. Misalnya "Peter$" hanya sesuai ketika kata "Peter" adalah kata terakhir dari sebuah paragraf, perhatikan "Peter" tidak dapat diikuti dengan titik.

$ berdiri sendiri cocok dengan akhir dari suatu paragraf. Dengan cara ini mungkin untuk mencari dan mengganti pemutus paragraf.

*

Nol atau lebih dari istilah ekspresi reguler segera sebelum itu. Misalnya, "Ab*c" sesuai dengan "Ac", "Abc", "Abbc", "Abbbc" dan so on.

+

Satu atau lebih dari istilah ekspresi reguler yang mendahuluinya. Misalnya, "AX.+4" ditemukan "AXx4", tapi bukan "AX4".

String terpanjang yang mungkin sesuai dengan persamaan ekspresi reguler ini dalam paragraf yang selalu cocok. Jika paragraf berisi string "AX 4 AX4", seluruh bagian disorot.

?

Zero or one of the regular expression term immediately preceding it. For example, "Texts?" matches "Text" and "Texts" and "x(ab|c)?y" finds "xy", "xaby", or "xcy".

\

The special character that follows it is interpreted as a normal character and not as a regular expression meta character (except for the combinations "\n", "\t", "\b", "\>" and "\<"). For example, "tree\." matches "tree.", not "treed" or "trees".

\n

A line break that was inserted with the Shift+Enter key combination when in the Find text box.

A paragraph break that can be entered with the Enter or Return key when in the Replace text box.

To change line breaks into paragraph breaks, enter \n in both the Find and Replace boxes, and then perform a search and replace.

\t

Sebuah karater tab. Dapat juga digunakan pada kotak Gantikan.

\b

A word boundary. For example, "\bbook" matches "bookmark" and "book" but not "checkbook" whereas "book\b" matches "checkbook" and "book" but not "bookmark".

Note, this form replaces the obsolete (although they still work for now) forms "\>" (match end of word) and "\<" (match start of word).

^$

Menemukan sebuah paragraf kosong.

^.

Menemukan karakter pertama paragraf.

& atau $0

Adds the string that was found by the search criteria in the Find box to the term in the Replace box when you make a replacement.

For example, if you enter "window" in the Find box and "&frame" in the Replace box, the word "window" is replaced with "windowframe".

You can also enter an "&" in the Replace box to modify the Attributes or the Format of the string found by the search criteria.

[...]

Any single occurrence of any one of the characters that are between the brackets. For example: "[abc123]" matches the characters ‘a’, ‘b’, ’c’, ‘1’, ‘2’ and ‘3’. "[a-e]" matches single occurrences of the characters a through e, inclusive (the range must be specified with the character having the smallest Unicode code number first). "[a-eh-x]" matches any single occurrence of the characters that are in the ranges ‘a’ through ‘e’ and ‘h’ through ‘x’.

[^...]

Any single occurrence of a character, including Tab, Space and Line Break characters, that is not in the list of characters specified inclusive ranges are permitted. For example "[^a-syz]" matches all characters not in the inclusive range ‘a’ through ‘s’ or the characters ‘y’ and ‘z’.

\uXXXX

\UXXXXXXXX

The character represented by the four-digit hexadecimal Unicode code (XXXX).

The character represented by the eight-digit hexadecimal Unicode code (XXXXXXXX).

For certain symbol fonts the Unicode code for special characters may depend on the font in use. The Unicode codes can be viewed by choosing Insert - Special Character.

|

The infix operator delimiting alternatives. Matches the term preceding the "|" or the term following the "|". For example, "this|that" matches occurrences of both "this" and "that".

{N}

The post-fix repetition operator that specifies an exact number of occurrences ("N") of the regular expression term immediately preceding it must be present for a match to occur. For example, "tre{2}" matches "tree".

{N,M}

The post-fix repetition operator that specifies a range (minimum of "N" to a maximum of "M") of occurrences of the regular expression term immediately preceding it that can be present for a match to occur. For example, "tre{1,2}" marches "tre" and "tree".

{N,}

The post-fix repetition operator that specifies a range (minimum "N" to an unspecified maximum) of occurrences of the regular expression term immediately preceding it that can be present for a match to occur. (The maximum number of occurrences is limited only by the size of the document). For example, "tre{2,}" matches "tree", "treee", and "treeeee".

(...)

The grouping construct that serves three purposes.

  1. To enclose a set of ‘|’ alternatives. For example, the regular expression "b(oo|ac)k" matches both "book" and "back".

  2. To group terms in a complex expression to be operated on by the post-fix operators: "*", "+" and "?" along with the post-fix repetition operators. For example, the regular expression "a(bc)?d" matches both "ad" and "abcd" in a search.; the regular expression "M(iss){2}ippi" matches "Mississippi".

  3. To record the matched sub string inside the parentheses as a reference for later use in the Find box using the "\n" construct or in the Replace box using the "$n" construct, where the reference to the first matched sub string in the current expression in the Find box is represented by "\1" in the Find box and by "$1" in the Replace box, the reference to the second matched sub string by "\2" and "$2" respectively, and so on.

For example, the regular expression "(890)7\1\1" matches "8907890890".

With the regular expression "\b(fruit|truth)\b" in the Find box and the regular expression "$1ful" in the Replace box occurrences of the words "fruit" and "truth" can be replaced with the words "fruitful" and "truthful" respectively without affecting the words "fruitfully" and "truthfully"
