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("
")){

    myVar = myVar.replaceAll("
", " ");

}

Answer 1


 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+" -> " "

Answer 2

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