Automatic Web Scraping and Wordpress Posting

I want to scrape information (including URLs) from a few websites and automatically generate job postings for my job board. I have installed the Wordpress plugin called "Scrapes" which does a decent job of scraping the data but I don't know how to use it to put data in the proper fields on my job posts. My job postings are handled by a job posting plugin and I need to retain them as they are so that my customers can post their jobs to my site. Might need to make custom code instead of using the "Scrapes" plugin. I need the scraping program to automatically run about once a day and do the following: scrape the sites, filter out any duplicate entries, create job posts, and populate the fields of the job posts with the job title, employer, job description, and URL. If it helps, my website is [login to view URL] and an example of a site I want to scrape is [login to view URL]
