What is 'regular expression' in SAP BC-ABA - ABAP Runtime Environment?


regular expression - Overview

  • Component: BC-ABA

  • Component Name: ABAP Runtime Environment

  • Description: A pattern of literal and special characters that characterize a string. When regular expressions are used in a text search, then you are interested in one or more occurrences of the string represented by the expression. The search using a regular expression is more powerful than searching for a simple string because the regular expression stands for a potentially endless number of strings that are searched for in parallel. As of Release 7.0, regular expressions can be used in ABAP in the FIND and REPLACE statements, as arguments of certain predefined functions, as well as in the CL_ABAP_REGEX and CL_ABAP_MATCHER classes.


regular expression - Details


  • Key Concepts: Regular expressions are a powerful tool used to search for patterns in text. They are used in SAP to search for specific strings of characters in ABAP code. Regular expressions are written using a special syntax that allows for the definition of complex patterns.
    How to use it: Regular expressions can be used in ABAP code to search for specific strings of characters. The syntax for writing regular expressions is based on the syntax of the Perl programming language. To use regular expressions, you must first define the pattern you want to search for. This can be done using the ABAP statement REGEX. Once the pattern is defined, you can use the ABAP statement FIND to search for the pattern in a string of text.
    Tips & Tricks: When writing regular expressions, it is important to remember that they are case sensitive. This means that if you are searching for a string of characters, you must make sure that the case of each character matches exactly what you are searching for. Additionally, it is important to remember that regular expressions can be used to search for patterns in text, not just exact strings of characters.
