Changeset 23489 for main/trunk/greenstone3/src/java/org/greenstone/gsdl3/action/FormatAction.java

Message:

Working on saving a format statement to the config file. This looks like it should work but changes in FormatAction have caused major issues with Document/Node violations. This is because saving required the format statement as a Document rather than a string (which did work). Added a check to GSXML for xmlNodeToString to check that attrs is not null (attrs will be null unless the node is an element).
