j2me怎么实现类似正则表达式的功能，提取文中字符？？？
下面为获取内容，现在想获取列表信息每行的第二列KH2009080003，第三列IDE技术有限公司：
<td><a href="Customer_info.aspx?cid=KH2009080003">KH2009080003</a></td>

[解决办法]
用这个：
- Java code
String html = "<td> <a href=\"Customer_info.aspx?cid=KH2009080003\">KH2009080003 </a> </td> <td>IDE技术有限公司 </td>"Pattern pat = Pattern.compile("href[^>]+?>([^<]+).+<td>([^<]+)<.+");Matcher mat = pat.matcher(html);while (mat.find()) { String fid = mat.group(1); String fname = mat.group(2); System.out.println("fid: " + fid); System.out.println("fname: " + fname); }
[解决办法]
j2me基本API里应该没有正则表达式相关的。
你这么大的数据量，只需要那么一点点有效信息，我建议LZ应该把这个数据提取过程放在server端进行，那样比较合理。
然后2楼说的这种正则表达式结构就可以用在服务器端了。服务器筛选数据结束后，只需要把有效信息发送给客户端即可。

最好不要把XML数据传送到手机上，直接用二进制数据，体积小，解析也方便
