Hex bytes can also be used in character classes. For example, to search for the bytes '3F 4D ? 0F' use the regular expression: \x3F\x4D.\x0F This syntax must be used for regular expressions even when the Find type is set to Hex Bytes in the Find Bar. When searching for hex bytes use the syntax '\x HH' to denote a hex byte where HH is the byte to find. For example to search for 'const int' or 'const char' use: const (int|char) For example to search for the colors red, green or blue, use: red|green|blueĪlternation can be combined with the '(' and ')' brackets to make more complex statements. The alternation operator '|' allows matching one out of several possible regular expressions. Warning: Using certain combinations of repetition operators can cause searches to be performed very slowly. Matches both the strings 'regular expression' and 'reg ex'. Repetition operations can also be used with the '(' and ')' brackets to indicate what is repeating. ![]() This regular expression matches one or more alphanumeric characters inside '' brackets. To match both the strings 'color' and 'colour' use the regular expressions: colou?rįor another example, to match a simple XML tag use: Regular expressions use a number of special control characters to control how the searches are done and the special characters are: ".^$()/\* For example, to find a string such as 'Green' just use the regular expression: Green Regular expressions look just like regular Find strings. Warning: Some regular expressions can be very complex and using certain regular expressions containing lots of repetition operators can cause searches to be performed very slowly. The full syntax of regular expressions are beyond the scope of this document but the following contains an introduction to the major features of regular expressions. Note that the letter 'R' will appear beside the word Options when regular expressions are enabled. Regular expressions can be used when performing a Find, Replace, Find In Files, or Replace In Files operation. To search for a regular expression, click the Options button in the Find Bar and enable the Search with Regular Expressions toggle (see the image below). Many different flavors of regular expressions exist and 010 Editor uses a syntax similar to Ruby/Perl. ![]() Regular Expressions are a powerful syntax for finding string patterns within a file.
