Sscanf () Sscanf () 2011-11-23 09:07:56........ I have been crawling recently. The STL of C ++ makes me tangle with the lack of support for regular expressions. I should use regular expressions unless I install the boost library, but I am very lazy, considering the running efficiency, boost has not been installed since it was downloaded. All functions used to extract information from crawlers are self
