XML editing w/o loosing formating

Sorry... I forgot the code tags...

This is a sample XML that I am using for testing.

<?xml version="1.0" encoding="UTF-8"?>

<sample attr1="v1"

attr2="v2"

attr3="v3">

<content anotherAttr="" />

</sample>

This is the output after a simple read and write

<?xml version="1.0" encoding="UTF-8"?><sample attr1="v1" attr2="v2" attr3="v3">

<content anotherAttr=""/>

</sample>

This is my test code:

public static void main(String[] args) throws Exception {

File fileInput = new File("input.xml");

File fileOutput = new File("output.xml");

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

factory.setExpandEntityReferences(false);

DocumentBuilder builder = factory.newDocumentBuilder();

document = builder.parse(fileInput);

TransformerFactory tFactory = TransformerFactory.newInstance();

Transformer transformer = tFactory.newTransformer();

DOMSource source = new DOMSource(document);

FileOutputStream fos = new FileOutputStream(fileOutput);

StreamResult result = new StreamResult(fos);

transformer.transform(source, result);

}

Use JDK 1.4.x for indentation to get added. Setting the indentation adds the newline between the xml declaration and he root element tag. Whitespace between elements is considered to be a text node and is preserved. Whitespace/newline between attributes is not a text node and is not preserved.

The following input.xml would produce the same output as an input.xml without whitespaces and newlines.

<?xml version="1.0" encoding="UTF-8"?>

<sample attr1="v1"

attr2="v2"

attr3="v3">

<content anotherAttr="" />

</sample>
