azim58 - How to find and replace regular expressions with groups in java

Pattern patt = Pattern.compile("(F)ourth");
Matcher m = patt.matcher(text);
StringBuffer sb = new StringBuffer(text.length());
while (m.find())



String text2 = m.group(1);


// ... possibly process 'text' ...


m.appendReplacement(sb, Matcher.quoteReplacement(text2));

m.appendTail(sb);
System.out.println(sb.toString());

===========================================================================
I'll just turn this into a function and put it into my useful tools

public String findAndReplacewithRegEx(String text, String find, String
replace)



Pattern patt = Pattern.compile(find);


Matcher m = patt.matcher(text);


StringBuffer sb = new StringBuffer(text.length());


while (m.find()) {


m.appendReplacement(sb, replace);

m.appendTail(sb);
return sb.toString();
}
