A more elegant way, that requires JDK1.4, would be this:
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class removeIt {
public static void main(String argv[]) {
String strHtml = "this is\nsome\nstring with\nchr's";
Pattern regPattern = Pattern.compile( "\n",
Pattern.DOTALL );
Matcher regMatcher = regPattern.matcher( strHtml );
strHtml = regMatcher.replaceAll( "<P>" );
System.out.println( strHtml );
}
}

| Hi
|
| Use the following method to replace all "\n" to "<P>"
|
|
| public String replaceAllValues(String stringValue, String
| oldString, String replaceString)
| {
| String temp1;
| String temp2;
| for(; stringValue.indexOf(oldString) > -1; stringValue =
| temp1 + replaceString + temp2)
| {
| temp1 = stringValue.substring(0,
| stringValue.indexOf(oldString));
| temp2 =
| stringValue.substring(stringValue.indexOf(oldString) +
| oldString.length(), stringValue.length());
| }
|
| return stringValue;
|
| }
|
| Eg. get the String from the database and call the above method
| using the following syntax
|
|
| out.println(replaceAllValues(log_message.get(i).toString(),
| "\n","<p>")); %>
|
|

| Subject: convert \n to <p> in jsp print statement
|
|
| Hi
|
| I have text which I submit to and retrieve from a database. When I
| submit to the database, it seems that the line breaks are preserved, but
| when I want to retrieve the text to my browser, everything becomes one
| long on-going stream of text. Presumably the \n line breaks exist in the
| database but they have to be converted to <p> tags for the browser to
| display them as line breaks.
|
| I am using a jsp which has a vector called log_messages to obtain the
| messages from the database. After obtaining them, I then display these
| messages with the following code.
|
| <% for (i =0; i < log_message.size(); i ++) { %>
| <p> Message: <%out.println(log_message.get(i).toString());%>
| <% } %>
|
| But I would like to convert the newline characters \n (which presumably
| are there in some of the message bodies) to <p> statements so new
| paragraphs will be showing. Is there an easy way to do this?
|
| Any help will be greatly appreciated.
|
| Thanks
|
| Hugo
