automate download of plain text file

I need a way to create a summary of 10 or so log files that are updated daily on the local interoffice website. The text files have a static name on the site.
The constraints that make this a tougher problem is that I can’t buy software (being a minion not a boss) and can’t use IIS. Hopefully open source stuff like free perl or even shell scripts to help me do this would be awesome. The data that is parsed gets written to an excel file. Is there a way to write a macro to either parse the webpage or download the files and then parse them? So VB macro or perl script or something else that helps…
