PHP How to print text AND html tags from DOMDocument, nodeValue instead only text?

Question

I am writing the following code to a .html file. I like to read out the values which is working. But I only get the text like you can see at "output". I need to print the html tags inside the <td> tags too!

Here is what the browser prints out:

hoehere Spruenge
2x 2x 2x 2x 

Adrenalin-Modus (Zeitlupe, staerkere Schlaege) (**)
2x 

maximaler Sex-Appeal
2x 3x 

and this is what I wont to get:

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">

and so on...

code inside the data.html file:

<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>

Answer 1

the following graps the html inside <td> :

$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";
}

Note in loop $i steps by 2 to skip headers. you should change the headers to <th> elements
