A simple PHP web scraper package -
Most websites do not offer the functionality to save a copy of the data which they display to your computer. The only option then is to manually copy and paste the data displayed by the website in your browser to a local file in your computer - a very tedious job which can take many hours or sometimes days to complete. Web Scraping is the technique of automating this process.
WebScrapa is a simple web scraper package written with PHP. It uses cURL to request and download a webpage. The downloaded webpage is converted to XML DOM object and XPath is used to navigate through elements in the XML DOM object.
