var RoaqyFPm={pages:1,data:["002042,华孚色纺,88,18837971,0.0226148126773274,增仓,15170345,4.136284615716,2015-03-31","600517,置信电气,1,7467160,0.00600002110046579,减仓,-6182622,-0.452946574531373,2015-03-31","002013,中航机电,1,3449707,0.00481610067451324,减仓,-6506264,-0.653503711491325,2015-03-31","600086,东方金钰,3,21662045,0.0481378777777778,减仓,-10277407,-0.321777812593654,2015-03-31","002276,万马股份,2,22154366,0.0235776173664484,减仓,-17645634,-0.443357638190955,2015-03-31"]}


从
http://datainterface.eastmoney.com//JS.aspx?type=8&js=var%20RoaqyFPm={pagespc),data:[(x)]}&stat=6&cmd=1&fd=2015-03-31
获取最新的数据条目文件 存为b.txt

对比b.txt 和a.txt 找出更新的条目
存为c.txt


大牛帮帮忙 在线等 不胜感激!!
