replaceAll <BR> with \n

I am not very good in the ways of Regex; therefor I am here to get help.

I am working in Java atm.

What I am looking for is a piece of code, that goes through a String and uses replaceAll() 

The tags I want to change from and to:
replaceAll() : <BR>, <br>, <br /> or/and <BR /> with “\n”

What I have tried to do, is the following from this JavaScript replace <br> with \n link but from debugging, I can see that it, doesn’t change the String.

MyCode

String titleName = model.getText();

// this Gives me the string comprised of different values, all Strings.

countryName<BR> dateFrom - dateTo: - \n hotelName <br />

// for easy overview I have created to variables, with the following values

String patternRegex = "/<br ?\\/?>/ig";
String newline = "\n";

With these two, I now create my titleNameRegex string, with the titleName String. 

String titleNameRegex = titleName.replaceAll(patternRegex, newline);

I have had a look at Java regex replaceAll multiline as well, because of the need to be case insensitive, but unsure where to put the flag for this and is it (?i) ?

So what I am looking for, is that my regex code should, replaceAll <BR> and <br /> with \n,
so that i looks properly in my PDF document.

Solution

  • /<br ?\\/?>/ig is Javascript regex syntax, in Java you need to use:

    String patternRegex = "(?i)<br */?>";

    (?i) is for ignore case comparison.
