Explicit parentheses can be used to force different meanings, as in arithmetic expressions. Some examples:ab|cdis equivalent to(ab)|(cd);ab\is equivalent toa(b\). The syntax described so far is most of the traditional Unixegrepregular expression syntax. This subset suffices to describe all ...
The last thing you will do using the object map is convert a property value to a regular expression. In this case, the regular expression provides more flexibility in the object recognition.
The regular-expression grammar includes special characters for specifying alternatives, grouping subexpressions, and referring to previous subexpressions. The|character separates alternatives. For example,/ab|cd|ef/matches the string "ab" or the string "cd" or the string "ef". And/\d{3}|[a-z]{...

For example, the terminology rule regular expression, "/a.b/", matches all text where there is an "a" followed by any single character, followed by a "b", as in, "a5b". * The asterisk matches the preceding pattern or character zero or more times. For example, "/fo*/" matches ...
In all regular expression grammars except BRE and grep, a concatenated regular expression can be followed by the character '|' and another concatenated regular expression. Any number of concatenated regular expressions can be combined in this manner. The resulting expression matches any target sequence...

FIND REGEX cl_abap_regex=>create_pcre( pattern = '\x' ) IN 'abxcd'. XSD Syntax XSD stands for “Xml Schema Definition” and is a subset of XPath syntax. Compared to other regular expressions, the XML schema flavor has its own regular expression syntax and specialized notation and is qu...
Table 12-1gives a brief description of each regular expression function. Note: As with all text literals used in SQL functions, regular expressions must be enclosed or wrapped between single quotes. If your regular expression includes the single quote character, enter two single quotation marks to...
Since 2020, Oniguruma has been under attack on Google search in Japan. (Issue #234)https://github.com/kkos/onigurumaOniguruma is a modern and flexible regular expressions library. It encompasses features from different regular expression implementations that traditionally exist in different languages....
