Java Removing Characters from XML

Question

I'm reading XML data using Java and DOM. When I print a variable to the console I notice it prints on two different lines.

Output:

Hello How are
you today?

When I go to the attribute I'm trying to print of the underlying XML document, I notice the following:

<element attribute = "Hello How are&#xD;&#xA;you today?"></element>

How do I remove the characters 
 from the attribute value in Java?

If the data from the attribute is stored in a Java String variable called myVar, I tried the following unsuccessfully:

if(myVar.contains("&#xD;&#xA;")){

    myVar = myVar.replaceAll("&#xD;&#xA;", " ");

}

Try replacing \r and \n.

 this is a line break embedded in XML, which is probably converted into characters 0xD 0xA (13 10) in java. So for the pattern, either use "\n\r", or use "\s+" -> " "

If he's using replaceAll, he should use "\\s+" since it takes a regular expression as its first argument. Using "s+" will just replace instances of 1 or more s characters.

Should probably be "\r\n" instead of "\n\r".

replaceAll("\\s+", " ") worked but so did replaceAll("\r\n", " "). On the other hand, "\n\r" as first argument to replaceAll did not work.
