-retrieve the error tags
-retrieve the corrected form in alphabetical which I will be in the corpus
what do you mean by retrieve?
if you mean have a set of programming tools which facilitate finding
occurences, then the answer is that a wide range of tools exist which
make this task relatively trivial, depending on what your markup
scheme is and what your programming platform (machine you want to run
on) is. perl, grep and icon are are programs (programming languages)
which you should learn about if you are willing to go the tool
oriented route.
on the other hand if you mean are there applications which will do the
job for you, then the answer is a much more qualified yes. on the pc,
in particular, many of the word processing programs are adding very
fast text search capability. some of these programs (word perfect is
an example of this) will produce indices to assist in the searching
task. if you can specify the error tags textually, and if you only
want to find and show the occurences of these tags, then this might be
all you need. some of these searching tools are beginning to have the
pretty much all of the capabilities of full text search systems.
on unix platforms there is also a great number of options, but based
on the headers from you email message, these would be of less interest
to you.
