public class RenameAttribute
This filter is used for renaming attribute names.
Regular expressions can be used in the matching and replacing.
See Javadoc of java.util.regex.Pattern class for more information:
http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html
-find <regexp> The regular expression that the attribute names must match. (default: ([\s\S]+))
-replace <regexp> The regular expression to replace matching attributes with. (default: $0)
-all Replaces all occurrences instead of just the first. (default: only first occurrence)
-R <range> The attribute range to work on. This is a comma separated list of attribute indices, with "first" and "last" valid values. Specify an inclusive range with "-". E.g: "first-3,5,6-10,last". (default: first-last)
-V Inverts the attribute selection range. (default: off)
