Programmer to write scripts to parse data

Hi, I have some HTML files. From those, you need to extract specify tabular data. (data within table/tr/td elements) and write them into a mysql database. There are 5-6 different formats of the data. The html files are well structured. You can use any open source parser (like <[login to view URL]>) OR write shell / perl scripts. Need the task completed within few hours. Should run on linux.
