Tutorial9: Regular Expressions

316 bytes removed, 08:54, 28 February 2021
→‎Complex Regular Expressions
The problem with using literals or simple regular expressions is that only <u>simple</u> or <u>general</u> patterns are matched.
 
For example, the pattern “'''the'''” would be matched for larger word containing that pattern like '''there''', '''they''', '''either''', '''them''', '''their''', etc.<br>Another problem is that you may want to search for pattern at a specific location within the string of text (like at the beginning or end).
There are other regular expression tools to provide more precise matches. These tools are '''complex''' and '''extended''' regular expressions.
