I would use Java Regular expressions.

Here is a class I wrote that simplifies using them. Also for more pattern examples look at this java doc: http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html.

For what you want to do this _expression_ should work: [\\r\\n\\f]

import java.util.regex.*;

public class Regtil {

private Regtil() {

}

/**

* Takes a string and based on a regular _expression_ replaces it with the given value.

* @param s The string to be changed

* @param p The regular _expression_. Example: [^\\w'] replaces all non a-z, A-Z characters

* @param r The String that you wish to replace the characters that match the pattern with.

* @see Pattern

* @return Changed string or if no changes original

public static String replaceReg(String s, String p, String r){

Pattern pn = Pattern.compile(p);

Matcher m = pn.matcher(s);

return m.replaceAll(r);

}

Example:

String s = Regtil.replaceReg(string, “[\\r\\n\\f]”, “ “);

Hope this helps.

Subject: Getting rid of Carriage returns

Hi All,

I have text I want to export to an Excel file. The text for a field may have carriage returns in it so I need to remove them and replace them with spaces. I’ve used StringTokenizer and then I used the Class String replace method and they both are not working for me.

Here is my little routine:

    public String removeReturns(String beforeStr) {
        String tempStr = "";
        StringTokenizer textTokens = new StringTokenizer(beforeStr, "\n", false);
        while(textTokens.hasMoreTokens()) {
            String aToken = (String)textTokens.nextToken();
            tempStr += aToken;
        }
        return tempStr;
    }

It doesn’t work. It still returns my string with the carriageretuns in it.

Can anyone help?
