I did not realize that each entry would have its own LT value. I had
thought that there were several sets of <SC> and <XC> with one <LT>. You
only showed one example...
I have modified the program to collect LT values at the same time it
collects SC and XC values. Also, it now collects whatever code appears
before the first SC code. I don't know what this code is for so I just
called the variable "before".
Notes on the code:
* Instead of doing this:
title = m.group(2)
title = title.strip()
I just do this:
title = m.group(2).strip()
You can apply string methods on any string, and it's convenient to do it
all in one line. There are several lines like that.
* There are two patterns to detect the LT code. The first one is for
finding it, and the second one is only for removing it. The second one
uses '^' to anchor the pattern, so it will only remove the LT code if the
LT code is the first thing in the string. The first pattern does not have
the '^' anchor so it will look ahead, past any number of <SC> codes, to
find the next <LT> code.
* Otherwise this is pretty much like the first version. It collects data,
saves it in a list, and then prints its output from the list.
I am busy now, so I won't have any time to make any more versions of this
for you. I hope you can study what I have done and understand how to apply
the ideas to your problems. Good luck!
