求table表格的正则表达式解决方法

求table表格的正则表达式
需要把[table][tr][td]test[/td][/tr][/table]替换成<table><tr><td>test</td></tr></table>
用正则表达式应该怎么做？
盼高手速降！！！

[解决办法]
这个也许是你要的。
UBB
String str=st;
str=str.replaceAll("\\[b\\](.*?)\\[/b\\]","<b>$1</b>");


反UBB
String str=st;
str=str.replaceAll("<b>(.*?)</b>","$1");

[解决办法]
//反UBB
public static String getUBB(String st){
if(st==null||st.length()==0){
return st;
}
String str=st;
str=str.replaceAll("<b>(.*?)</b>","$1");
str=str.replaceAll("<h6>(.*?)</h6>","[h6]$1[/h6]");
str=str.replaceAll("<h5>(.*?)</h5>","[h5]$1[/h5]");
str=str.replaceAll("<h4>(.*?)</h4>","[h4]$1[/h4]");
str=str.replaceAll("<h3>(.*?)</h3>","[h3]$1[/h3]");
str=str.replaceAll("<h2>(.*?)</h2>","[h2]$1[/h2]");
str=str.replaceAll("<h1>(.*?)</h1>","[h1]$1[/h1]");
str=str.replaceAll("<u>(.*?)</u>","$1");
str=str.replaceAll("<i>(.*?)</i>","[en]$1[/en]");
str=str.replaceAll("<font color=black>(.*?)</font>","[black]$1[/black]");
str=str.replaceAll("<font color=white>(.*?)</font>","[white]$1[/white]");
str=str.replaceAll("<font color=red>(.*?)</font>","[red]$1[/red]");

str=str.replaceAll("<IMG src=(.*?) border=0>","[img]$1[/img]");
