COBOL copy books, if I remember correctly, are usually pretty simple: I would think that picking out the level number, name, and picture of each field would be fairly easy using regular expressions, and turning the hierarchy from a flat list with level numbers into a true XML hierarchy shouldn't be too hard using for-each-group. (One thing I've never done is to use for-each-group recursively to handle infinite nesting of groups, but it should be possible in theory!)
