一个通用html抽取类
首先先放正文,我把换行去掉了为了省正则的写法.下面以新浪微博为例子



然后就是我的代码了

这里是调用例子




这个是返回结果


  看了，蛮不错的String beginRegex = "<div id=\"main\" style=\"background:none;\">";
String endRegex = "<iframe id=\"ifr\" width=\"100%\" height=\"0\" scrolling=\"no\" frameborder=\"0\" src=\"/n?cmd=2&page=http%3A%2F%2Fnews.yesky.com%2F346%2F30918346.shtml&pn=1&tn=newsrela&s_richtext=1\"></iframe>";
AnsjPaser ansjHtml = new AnsjPaser(beginRegex, endRegex, br,
AnsjPaser.TEXTTEGEX);
//SplitPaser paser = new SplitPaser();
//paser.splitString(beginRegex, endRegex, br);
// 正文抽取
beginRegex = "<p class=\"<.*?>\"><a href=\"<.*?>\" target=\"<.*?>\" mon=\"<.*?>\" >";
endRegex = "<a.*?>";
AnsjPaser ansjContent = new AnsjPaser(beginRegex, endRegex)
.addFilterRegex("<.*?>");
// 时间抽取
beginRegex = "<div class=\"abstract\">";
endRegex = "来源：<.*?></div>";
AnsjPaser ansjPubTime = new AnsjPaser(beginRegex, endRegex);
// 来源抽取
beginRegex = "<span class=\"resource\">(来源：";
endRegex = ")</span></p>";
AnsjPaser ansjFrom = new AnsjPaser(beginRegex, endRegex);
// 转发抽取
//beginRegex = "<strong lang=\"CD0023\" pop=\"true\">转发</strong><strong id=\"num_\\d*?\" rid=\"\\d*?\" type=\"rttCount\">\\(";
//endRegex = "\\)</strong>";
//AnsjPaser ansjRepeat = new AnsjPaser(beginRegex, endRegex);
//// 评论抽取
//beginRegex = "<strong lang=\"CL1004\">评论</strong><strong rid=\"\\d*?\" type=\"commtCount\">\\(";
//endRegex = "\\)</strong>";
//AnsjPaser ansjComment = new AnsjPaser(beginRegex, endRegex);

// 开始抽取
while (ansjHtml.hasNext()) {

String c1 = ansjHtml.getNext();

System.out
.println("=========================================================================");

System.out.println("时间:" + ansjPubTime.reset(c1).getText());

System.out.println("来源:" + ansjFrom.reset(c1).getText());

//String str = ansjRepeat.reset(c1).getText();
//System.out.println("转发:"
//+ ((str == null || "".equals(str)) ? "0" : str));

//str = ansjComment.reset(c1).getText();
//System.out.println("评论:"
//+ ((str == null || "".equals(str)) ? "0" : str));
//
//System.out.println("正文:" + ansjContent.reset(c1).getText());
//
}

}

}

我把你的html信息提取下来重命名为王龙君.html现在问题停在路径读取抛异常     9 楼    chenpenghui    2012-01-19              好像不错的样子，先顶一个，但是我感觉，用jsoup的话更方便点，网页是一棵树，直接取节点好了。毕竟写正则比较麻烦。
