→Complex Regular Expressions
===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).
