正则表达式难题！！！
如何获取一段html中包含特定字符的某个标签对！
如：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN ">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<META NAME= "Generator " CONTENT= "EditPlus ">
<META NAME= "Author " CONTENT= " ">
<META NAME= "Keywords " CONTENT= " ">
<META NAME= "Description " CONTENT= " ">
</HEAD>
<BODY>
<TABLE>
<TR>
<TD> asdf </TD>
<TD> asdf </TD>
</TR>
<TR>
<TD> #asdf </TD>
<TD> asdf </TD>
</TR>
<TR>
<TD> sdf </TD>
<TD> asdf </TD>
</TR>
<TR>
<TD> sdf </TD>
<TD> asdf </TD>
</TR>
</TABLE>
</BODY>
</HTML>

<TD> asdf </TD>
