Simple research program search help

[MaoMao]

New in testing a research program for download log.

The process is to search the number of Downloads for the program names in the txt file.

Result can be displayed in IE new tab page and write to excel file.

Can anyone help the following problem.

1) How to identify and What is the search keywork object name in the http://sourceforge.net page?

2) What is the "Download log" result object name in the source page?

3) Is the Excel program correct in setting and writing the file?
