Perl website scraping

The program must be in perl. This is not negotiable.

The program scrapes historic Analysts Upgrade/Downgrade Announcement data from the website [url removed, login to view] and outputs the data into a series of comma delimited text files. The website can be found here:

[url removed, login to view]

The script will parse the Upgrades/Downgrades Archive, starting and ending with dates specified by command line arguments. By default, these dates will be 1/1/2000 for the start date, and todays date as the end date.

1) First the script obtains a full list of company tickers that have had Analysts announcements between the two dates. This is achieved by searching each page for every date from the diary e.g by changing the last part of the following address:

[url removed, login to view]

A non redundant ticker list for all tickers is generated from the “ticker” field of each table. Thus the script obtains every ticker that has associated Analysts data.

2) The script will then obtain all historic Analysts Upgrade/Downgrade Announcement data from the website:

[url removed, login to view]

Each of the ticker symbols is used to search using the “QuickSearch” button on the above webpage. I need data for each ticker ticker from the “Archived Results Upgrades/Downgrades” table from the resulting search.

I need the following fields extracted:

- Date

- Brokerage Firm

- Action

- From

- To

- Old

- New

The data extracted will only be for the dates between the “FirstDate” and “EndDate”.

This data is finally outputted to an individual file for each ticker symbol. The filename is SYMBOL.AA. It is a comma separated file. It starts with the oldest to the newest data. . Each file will then have the data for that symbol in chronological order. The format is as follows:

A single header line as:

“Date, Time, Brokerage Firm, Action, From, To, Old, New”

Each file will then have the data for that symbol in chronological order.

The next lines are comma separated as follows:

“Date” is in the format YYYYMMDD.

“Time” is always 0930

The following fields are as from [url removed, login to view]

The numbers for the fields Old and New should have the $ sign removed.

Empty Fields should be filled with the symbol “--"
