PHP 如何从 DOMDocument 打印文本和 html 标签，nodeValue 而不是仅文本

我正在将以下代码写入.html文件。我喜欢读出有效的值。但我只得到您在"输出"中看到的文本。我也需要在<td>标签内打印 html 标签！

以下是浏览器打印的内容：

hoehere Spruenge
2x 2x 2x 2x 
Adrenalin-Modus (Zeitlupe, staerkere Schlaege) (**)
2x 
maximaler Sex-Appeal
2x 3x 

这就是我不会得到的：

hoehere Spruenge 
2x <img src="images/cheats/psx/o.gif"> 2x <img src="images/cheats/psx/d.gif"> 2x <img src="images/cheats/psx/o.gif"> <img src="images/cheats/psx/l.gif"> <img src="images/cheats/psx/r.gif"> <img src="images/cheats/psx/ve.gif"> 2x <img src="images/cheats/psx/r2.gif">

等等...

data.html 文件中的代码：

<TABLE BORDER CELLPADDING="2">
  <TR>
    <TD>höhere Sprünge</TD>
    <TD>2x <img src="images/cheats/psx/o.gif"> 2x <img src="images/cheats/psx/d.gif"> 2x <img src="images/cheats/psx/o.gif"> <img src="images/cheats/psx/l.gif"> <img src="images/cheats/psx/r.gif"> <img src="images/cheats/psx/ve.gif"> 2x <img src="images/cheats/psx/r2.gif"></TD>
  </TR>
  <TR>

    <TD>2x <img src="images/cheats/psx/k.gif"> <img src="images/cheats/psx/ve.gif"> <img src="images/cheats/psx/r1.gif"> <img src="images/cheats/psx/l1.gif"> <img src="images/cheats/psx/k.gif"> <img src="images/cheats/psx/u.gif"> <img src="images/cheats/psx/l.gif"> <img src="images/cheats/psx/k.gif"></TD>
  </TR>
  <TR>
    <TD>maximaler Sex-Appeal</TD>
    <TD><img src="images/cheats/psx/ks.gif"> 2x <img src="images/cheats/psx/d.gif"> <img src="images/cheats/psx/o.gif"> <img src="images/cheats/psx/ks.gif"> <img src="images/cheats/psx/r1.gif"> <img src="images/cheats/psx/l2.gif"> <img src="images/cheats/psx/o.gif"> <img src="images/cheats/psx/d.gif"> 3x <img src="images/cheats/psx/l1.gif"></TD>
  </TR>
  <TR>
</TABLE>
