/**
 * Turn an object into a simple XML Element, supporting custom property
 * editors.//  ww w .  j ava  2s .  c  o m
 * 
 * <p>
 * The returned XML will be a single element with all JavaBean properties
 * turned into attributes. For example:
 * <p>
 * 
 * <pre>
 * &lt;powerDatum
 *   id="123"
 *   pvVolts="123.123"
 *   ... /&gt;
 * </pre>
 * 
 * <p>
 * {@link PropertyEditor} instances can be registered with the supplied
 * {@link BeanWrapper} for custom handling of properties, e.g. dates.
 * </p>
 * 
 * @param bean
 *        the object to turn into XML
 * @param elementName
 *        the name of the XML element
 * @return the element, as an XML DOM Element

/**
 * Update an existing article by copying properties from the new one over.  Note that we can't call saveOrUpdate,
 * since the new article is not a persistent instance, but has all the properties that we want.
 * <p/>//w w  w  . j  a v  a 2 s . c  om
 * See <a href="http://stackoverflow.com/questions/4779239/update-persistent-object-with-transient-object-using-hibernate">this
 * post on stack overflow</a> for more information
 * <p/>
 * For collections, we clear the old property and add all the new entries, relying on 'delete-orphan' to delete the
 * old objects. The downside of this approach is that it results in a delete statement for each entry in the old
 * collection, and an insert statement for each entry in the new collection.  There a couple of things we could do to
 * optimize this: <ol> <li>Write a sql statement to delete the old entries in one go</li> <li>copy over collection
 * properties recursively instead of clearing the old collection.  e.g. for {@link Article#assets}, instead of
 * clearing out the old list, we would find the matching asset by DOI and Extension, and update its properties</li>
 * </ol>
 * <p/>
 * Option number 2 is messy and a lot of code (I've done it before)
 *
 * @param article         the new article, parsed from the xml
 * @param existingArticle the article pulled up from the database
 * @throws IngestException if there's a problem copying properties or updating
