Regular expression is a mode in combination with text description characters. Use them in code search help to describe some concepts, such as "rows starting with 'VAR'" and "Intributes of numbers". For more information on search, see Search and Replace Tags and properties.
The following table lists the special characters used in the regular expression, its meaning and usage examples. To search for text containing a particular character in the table, add a backslash in front of the special character to "escape". For example, if you want to search the actual asterisk in a Some Conditions Apply * phrase, your search mode should be similar to: apply / *. If you don't make an asterisk escape, you will find all matching items of "Apply", "ApplyY", "Applyy", "ApplyY", not just those who follow the asterisk. .

[E-G] "g" [g "[g" [ABC] in "F" in "Fol" in "BED" is matched, "g" [ABC] in parentheses is not enclosed in parentheses. Specify a range of characters (for example, [^ A-F] equivalent to [^ Abcdef]) with a hyphen. [^ Aeiou] The "K" / B word boundary (such as space or auto-return "in" B "and" EEK! "In" R "," Book "in" ORANGE "is initially matched. / BB matches "B" in "BOOK", but there is no content other than any match / B word boundary in "GoOBer" and "Snob". / BB matches "B" in "GOOBER", but there is no match / d any numeric character in "Book".

Make sure if no regular expressions are used, cancel the selection of "ignoring blank difference" at the time of search. Note that this matches a particular character, not a newline in a general sense; for example, it does not match the
tag or
tag. The Enter is displayed in the "Design" view as space instead of a newline. The packets to be referenced later in the regular expression in the regular expression. Then use $ 1, $ 2, $ 3, etc. in the "Replace" domain, reference the first, second, third, and more brackets.
Note: Use / 1, / 2, / 3, etc. (rather than $ 1, $ 2, $ 3) in the "Find Content" text box to reference your earlier brackets in the regular expression.
For example, by searching (/ D ) // (/ d ) // (/ d ) and replaced it with $ 2 / $ 1 / $ 3, it can exchange days and months in the date separated by the slash (therefore can be in the US style date and Convert between European style dates).
