Class REConverter

java.lang.Object
  com.cleancode.format.REConverter

public class REConverter
extends Object

Converts a text file using a series of regular expressions replacements. This class implements a completely generic text processing engine. You provide a set of regular-expression based rules, then invoke convert to run the engine. The simplest example is:

 static final REPiece[] PATTERNS = { ... };
 String outputText = (new REConverter(PATTERNS)).convert(inputText);
 

The devil is in the details, of course. That is, you need to define a set of regular expression rules in the PATTERNS variable. Here is the beginning of a set of rules to strip HTML markup from web text:

 static final REPiece[] PATTERNS = {
          new REPiece("italic",
            "<I>(.*?)</I>", "*$1*", Pattern.CASE_INSENSITIVE),
          new REPiece("rules",
            "<HR>", NL+"====================="+NL, Pattern.CASE_INSENSITIVE),
          new REPiece("non-breaking spaces",
            " ", " "),
          new REPiece("all other tags",
            "<[^>]*>", "", Pattern.DOTALL),
 };
