/text/shared/01/02100001.xhp Sun Microsystems, Inc. UFI: fixed #i24613#, plus many changes due to #i18379# regular expressions; list of lists;regular expressions List of Regular Expressions Character Result/Use Any character Represents any single character unless otherwise specified. . Represents any single character except for a line break or paragraph break. For example, the search term "sh.rt" returns both "shirt" and "short". ^ Only finds the search term if the term is at the beginning of a paragraph. Special objects such as empty fields or character-anchored frames, at the beginning of a paragraph are ignored. Example: "^Peter". $ Only finds the search term if the term appears at the end of a paragraph. Special objects such as empty fields or character-anchored frames at the end of a paragraph are ignored. Example: "Peter$". * Finds zero or more of the characters in front of the "*". For example, "Ab*c" finds "Ac", "Abc", "Abbc", "Abbbc", and so on. + Finds one or more of the characters in front of the "+". For example, "AX.+4" finds "AXx4", but not "AX4". The longest possible string that matches this search pattern in a paragraph is always found. If the paragraph contains the string "AX 4 AX4", the entire passage is highlighted. ? Finds zero or one of the characters in front of the "?". For example, "Texts?" finds "Text" and "Texts" and "x(ab|c)?y" finds "xy", "xaby", or "xcy". \ Search interprets the special character that follows the "\" as a normal character and not as a regular expression (except for the combinations \n, \t, \>, and \<). For example, "tree\." finds "tree.", not "treed" or "trees". \n Represents a line break that was inserted with the Shift+Enter key combination. To change a line break into a paragraph break, enter \n in the Search for and Replace with boxes, and then perform a search and replace. \t Represents a tab. You can also use this expression in the Replace with box. \> Only finds the search term if it appears at the end of a word. For example, "book\>" finds "checkbook", but not "bookmark". \< Only finds the search term if it appears at the beginning of a word. For example, "\<book" finds "bookmark", but not "checkbook". ^$ Finds an empty paragraph. ^. Finds the first character of a paragraph. & Adds the string that was found by the search criteria in the Search for box to the term in the Replace with box when you make a replacement. For example, if you enter "window" in the Search for box and "&frame" in the Replace with box, the word "window" is replaced with "windowframe". You can also enter an "&" in the Replace with box to modify the Attributes or the Format of the string found by the search criteria. [abc123] Represents one of the characters that are between the brackets. [a-e] Represents any of the characters that are between a and e. [a-eh-x] Represents any of the characters that are between a-e and h-x. [^a-s] Represents any character that is not between a and s. \xXXXX Represents a special character based on its four-digit hexadecimal code (XXXX). The code for the special character depends on the font used. You can view the codes by choosing Insert - Special Character. | Finds the terms that occur before or after the "|". For example, "this|that" finds "this" and "that". {2} Defines the number of times that the character in front of the opening bracket occurs. For example, "tre{2}" finds "tree". {1,2} Defines the number of times that the character in front of the opening bracket can occur. For example, "tre{1,2}" finds both "tree" and "treated". {1,} Defines the minimum number of times that the character in front of the opening bracket can occur. For example, "tre{2,}" finds "tree", "treee", and "treeeee". ( ) Defines the characters inside the parentheses as a reference. You can then refer to the first reference in the current expression with "\1", to the second reference with "\2", and so on. For example, if your text contains the number 13487889 and you search using the regular expression (8)7\1\1, "8788" is found. You can also use () to group terms, for example, "a(bc)?d" finds "ad" or "abcd". [:digit:] Represents a decimal digit. [:space:] Represents a white space character such as space.UFI: see #i41706# [:print:] Represents a printable character. [:cntrl:] Represents a nonprinting character. [:alnum:] Represents an alphanumeric character ([:alpha:] and [:digit:]). [:alpha:] Represents an alphabetic character. [:lower:] Represents a lowercase character if Match case is selected in Options. [:upper:] Represents an uppercase character if Match case is selected in Options. For a logical search expression with nested AND and OR operators, use parentheses.
