摘要：Web data analysis applications such as extracting mutual funds information from a website, daily extracting opening and closing price of stock from a web page involves web data extraction. Every time you need analyze data, you need to visit number of web sites. It is very time consuming process to construct wrapper to visit those sites and collect data.
