<a href="#" class="J_show_list J_MakePoint" data-point-val="tbrate.2.3.1" data-param="timeLine=-30&amp;result=1">23323</a>正则匹配这个就可以了。

Answer 6

我发现PHP版一直删我楼，艹了

Answer 7

我要同时匹配这两段字符，该如何写正则呢
<a href="http://ratehis.taobao.com/user-rate-39512--isarchive|true--detailed|1--goodNeutralOrBad|1--timeLine|-211--receivedOrPosted|0--buyerOrSeller|0.htm#RateType" class="J_MakePoint" data-point-val="tbrate.2.5.1">4508530</a><a href="#" class="J_show_list J_MakePoint" data-point-val="tbrate.2.4.1" data-param='timeLine=-210&result=1'>289048</a>提示：
第一个的：class="J_MakePoint" data-point-val="tbrate.2.5.1">4508530</a>
第二个的：class="J_show_list J_MakePoint" data-point-val="tbrate.2.4.1" data-param='timeLine=-210&result=1'>289048</a>
都是需要提取<a>标签内的数字，如第一个中搞定4508530和第二个中的289048，用一个正则匹配
