Rule editor captures data

Here, the main task is to set the target address and regular expression rules. I live in Shenzhen, IT industry of Shenzhen is more concerned, so often see the following address, http://www.iteer.net/modules/xdirectory/viewcat.php? Cid = 217 to understand the current situation of IT companies in Shenzhen.

I often think of capturing the data into my computer, which is also a reason for Data Loader. Please set a test page address as http://www.iteer.net/modules/xdirectory/singlelink.php? Cid = 217 & lid = 2558, and then apply the following regular expression to capture data.

Company Name: <Div \ sclass = "* company_title" *> (? <Title> \ W *) \ s? <?

Address: </strong> (? <Address>. *) \ s *

Scale: </strong> (? <Count>. *) person

Contact number. * </strong> (? <Tel>. *) \ s * <br>?

Fax. * </strong> (? <Fax>. *) \ s * <br>?

Email: email. * </strong>. * mailto :(? <Mail> \ W *@.*)"

Website. * \ s * </strong> <A \ s * href = "(? <Website>. *) "\ s * Target

Rating: Id = xspace-rates-tip> (? <Rating>. *) </span>

Comment time: class = comdatecaption> .*(? <Time> \ D {4}-\ D {2}-\ D {2 })

This step is done and the rules are saved. Then open segment run to select the rule you want to run and start analysis and download in the background.Program.
