Answer 1

Use MavenXpp3Reader to read and MavenXpp3Writer to write Model objects. Simple example:

String baseDir = "/your/project/basedir/";

//Reading
MavenXpp3Reader reader = new MavenXpp3Reader();
Model model = reader.read(new FileInputStream(new File(baseDir, "/pom.xml")));

//Editing
model.setUrl("http://stackoverflow.com");

//Writing
MavenXpp3Writer writer = new MavenXpp3Writer();
writer.write(new FileOutputStream(new File(baseDir, "/pom.xml")), model);

And notice that any comment, extra white spaces or lines will be removed from the file.
