</html>
<?php
if(isset($_POST['data']))
{
echo "<div id=tag0>";
echo $_POST['data'] ;
echo "</div>";
}
?>
<?php
if(isset($_POST['data']))
{
//divide start tag and end tag
$array=str_split($_POST['data']);
$tag=array();
$i=0;
$tag_close=false;
$tag_star=false;
foreach($array as $key => $value)
{
// echo "<hr>" .$i." is value of i<hr>";
// echo $tag_close . $tag_star;
//<html></html>
// if($value=' ')
// {
// }
// else
if($value == '>')
{
$tag_close=true;
$tag_star=false;
$i++;
}
else if($value == '<')
{
$tag_star=true;
}
else if($tag_star)
{
$tag_close=false;
if(!isset($tag[$i]))
{
$tag[$i]='';
}
$tag[$i]=$tag[$i].$value;
}
}
//writing javascript
$k=1;
$tag_name='';
$end_tag_started=false;
$attribut=array();
$attribut_val=array();
$j=0;
$o=0;
$attribut_value_started=false;
// one y one tag adding and it's attriut
foreach($tag as $key => $value)
{
$t='tag'.$k;
$p='tag'.$o;
$value_aaray=str_split($value);
$tag_name='';
$attribut=array();
$attribut_val=array();

$attribut_value_started=false;
}
else if($val_array == "=")
{
$attribut_value_started=true;
}
else
{
if($attribut_value_started)
{
@$attribut_val[$j]=$attribut_val[$j].$val_array;
}
else
{
@$attribut[$j]=$attribut[$j].$val_array;
}
}
}
break;
}
if($val == '/')
{
$end_tag_started=true;
break;
}
$tag_name=$tag_name.$val;
}
if(! $end_tag_started)
{
echo "<br> \t";
echo $t ."= document.createElement(\"".$tag_name."\");";
echo "<br> \t";
for($l=1;$l<count($attribut);$l++)
{
echo " $t.setAttribute(\"".@$attribut[$l]."\",\"".@$attribut_val[$l]."\");<br>";
}
}
$end_tag_started=false;
$k++;
}
echo "<hr>'tag'";
print_r($tag);
echo "<hr> ' letter array ' ";
print_r($array);
// for appendChild code but not working
$a=array();
for($i=0;$i<(count($tag));$i++)
{
$val=str_split($tag[$i]);
if($val[0]=="/")
{
echo "<hr>";
echo $a[]=" tag". ( $i-2 ) .".appendChild(tag". ($i-1).");";
}
}
}
?>
