Changeset 33730 for main/trunk/gli/src/org/greenstone/gatherer/metadata/MetadataXMLFile.java

Message:

Finally, got the code back to achieving the same thing as the partial bugfix from yesterday to the issue of non-ascii meta filenames not retaining any meta assigned at file level. The difference in today's commit is that the reworking does it Dr Bainbridge's way: instead of hex encoding one value to compare to a hex encoded value, am now ensuring both are decoded hex values when comparing. Adding a bugfix to recently introduced FilenameEncoding.decodeStringContainingHexEntities() since I forgot to test for the most basic case of all: when a string is not hex encoded, it should return the same string (the bug caused it to return nothing and which caused my rewrite of yesterday's work to look like it wasn't working for so long).
