想从上面网址抓中间Review部分
Review是在本文位置
<span class=rkr>
本文
<br>
表达式这样写<span class=rkr>\s(.*)\s<br>
完全抓不到东西
然後\s(.*)\s<br>这样抓到文章九成
剩下这段抓不到
Straight photography (Street, documentary, and environmental portraiture) is
primarily concerned with capturing images of people in uncontrived, naturally
lit and candid settings that evocatively depict or dramatically reveal some
aspect of the human condition. In addition to being a first rate general
purpose digicam, the nifty little SX210 is almost perfect for “straight”
photography - it is compact, responsive, unobtrusive, features a 14x zoom
(for a little extra standoff room) and dependably generates first rate images.
明明就有写换行为什麽会抓不到在同一行的这一段
然後第一个和第二个的差别只差<span class=rkr>
然後就全没了?????
好苦恼啊
希望有人能解答
谢谢
