Description

When I have a Windows Line Break (CR+LF) in a CDATA section, the transformer turns it into (CR+CR+LF), which most editors display as an extra blank line. Test code:

import static org.junit.Assert.assertEquals;

import java.io.StringWriter;

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.junit.Test;
import org.w3c.dom.CDATASection;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class XmlCdataWithCrTest {
private static final String LINE_SEPARATOR = System.getProperty("line.separator");

@Test
public void testXmlCdataWithCr() throws TransformerException, ParserConfigurationException

{ Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument(); Element root = doc.createElement("root"); doc.appendChild(root); CDATASection cdataSection = doc.createCDATASection("a" + LINE_SEPARATOR + "b"); root.appendChild(cdataSection); StringWriter writer = new StringWriter(); Transformer transformer = TransformerFactory.newInstance().newTransformer(); transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.transform(new DOMSource(doc), new StreamResult(writer)); String result = writer.toString();// .replace("\r\r", "\r"); String expected = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><root><![CDATA[a" + LINE_SEPARATOR + "b]]></root>" + LINE_SEPARATOR; assertEquals(expected, result); }

}
