The XML classes in the com-hfg library are designed to let you construct or parse xml content in a modular, object-oriented way. The XMLTag class is the base tag for the HTML and SVG classes.
XMLTag tag = new XMLTag("TagOne");
tag.setAttribute("foo", "bar");
tag.addContent("Hello World");
tag.addSubtag(new XMLTag("TagTwo"));
System.out.println(tag.toXML());
would produce the following XML snippet:
<TagOne foo='bar'>Hello World<TagTwo /></TagOne>
