正则表达式只用TR提取TR [英] Regex for extracting only TR with TDs

问题描述

早上好

我试图得到一个必须有一个或多个表格单元（TD）的表格行（TR）：

I'm trying to get a table row (TR) that must have one or more table cells (TDs):

拥有此字符串

<TABLE>
<TR valign="top">
  <TH>First</TH>
  <TH>2nd</TH>
  <TH>3rd</TH>
  <TH>4th</TH>
</TR>
<TR valign="top">
  <TD width="15%">Michael Jackson</TD>
  <TD width="5%">Cramberries</TD>
  <TD width="25%">Pixies</TD>
  <TD width="45%">The Ramones</TD>
</TR>
</TABLE>

我想要：

I would like to get:

<TR valign="top">
  <TD width="15%">Michael Jackson</TD>
  <TD width="5%">Cramberries</TD>
  <TD width="25%">Pixies</TD>
  <TD width="45%">The Ramones</TD>
</TR>

使用嵌套的TD提取一个或多个TR的最佳模式是什么？

what would be the best pattern for extracting one or more TRs with nested TDs?

This one is working

Regex.Matches(sourceHtmlString, @"(?<1><TR[^>]*>\s*<td.*?</tr>)", 
              RegexOptions.Singleline | RegexOptions.IgnoreCase)
