Question

我正在将以下代码写入.html文件。我想读出有效的价值观。但我只能得到你在“输出”中看到的文字。我还需要在<td>标签内打印html标签！

以下是浏览器打印出来的内容：

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">

依旧......

data.html文件中的

代码：

<TABLE BORDER CELLPADDING="2">

以下内容抓取<td>内的html：

$str = '
<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>Adrenalin-Modus (Zeitlupe, stärkere Schläge) (**)</TD>
    <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>
';

$doc = new DOMDocument();
$doc->loadHTML($str);
$tds = $doc->getElementsByTagName('td');
$doc->loadHTML($str);

//header("Content-type: text/plain");

$len = $tds->length;
for($i = 1; $i < $len; $i += 2){
    echo $doc->saveXML($tds->item($i)) . "\n";
}

请注意循环$i步骤2跳过标题。您应该将标题更改为<th>元素

PHP如何从DOMDocument打印文本和html标签，nodeValue只打印文本？
