我无法删除字符串中的一系列单词

I made a function in php that returns the result of a POST and converts it to a string using cURL . However, my code returns a lot of useless information. I wanted to manipulate the string so that I could delete all the useless information and leave only what is useful, that is, delete everything that comes before the word </SCRIPT> in string.

I'm putting a piece of string that I get (there is a lot more information before that). I wanted my string was equal to that in the interval between <dt><b><font color="maroon">como</font></b> and </table>.

<SCRIPT LANGUAGE='JavaScript1.1'><!--
  var objForm = document.theform;
  var index = 0;
  objForm.text.value="como n\u00e3o amar uma pessoa t\u00e3o linda";

  objForm.text.focus();
  checkIt(objForm.parser, 'parse');

  checkIt(objForm.visual, 'niceline');

function getIndex(elemID, testValue){
  for(i=0; i<elemID.length; i++){
    if (elemID[i].value == testValue)
      return i;
  }
  return 0;
}

function checkIt(element, value) {
  if (element.length==1 || element.type=="checkbox"){
    element.checked=1;
    element.selected=1;
  }
  else if (element.length>1){
    index = getIndex(element, value);
    element[index].selected=1;
    element[index].checked=1;
  }
}
//-->
</SCRIPT>
      <dl>
**<dt><b><font color="maroon">como</font></b>** 

<font color="maroon">[como]</font>  &lt;rel&gt; &lt;ks&gt; <font color="blue"><b>ADV</b> </font> <font color="darkgreen">@ADVL&gt;</font> <font color="darkgreen"><b>@#FS-ADVL</font></b> <font color="darkgreen"><b>@#FS-N&lt;</font></b>

<dt><b><font color="maroon">linda</font></b> 

<font color="maroon">[lindo]</font>  <font color="blue"><b>ADJ</b> F S </font> <font color="darkgreen">@N&lt;</font>
<dt><b><font color="maroon">.</font></b> 

</dl>
  </td>
  <td>&nbsp;
      </td>
</tr>
</table>

    You could use strpos to find the position of where you want to split the string. Then use substr to split the string from that position.
