Is it possible in php to get certain parts of a remote page? Like some certain parts or a table with info?

I think html would be a problem but XML is possible.

Why not? You can use fopen or other file functions (assuming fopen is allowed) to access remote files.

this should do it....

if(!($myFile=fopen("put here url to grab from","r")))
{
echo "No source available";
exit;
}
while(!feof($myFile))
{
// Read each line and add to $myLine
$myLine.=fgets($myFile,255);
}
fclose($myFile);
$start="put here whatever html to start";
$end="end with this html";
$start_position=strpos($myLine, $start);
$end_position=strpos($myLine, $end)+strlen($end);
$length=$end_position-$start_position;
$myLine=substr($myLine, $start_position, $length);
// Display HTML
echo $myLine;

Whatever you do, make absolutely certain that the URL or path you use is properly sanitized / validated / initialized / ... (if its hardcoded, all the better, but also make sure no-one can overwrite your included html file) to ensure there is NO opportunity for you ending up echoing out malicious code (a form of XSS attack).

Functions such as fopen() can be quite dangerous if not coded right. Even include(), require(), ... basically anything that can take a path/URL ... can be dangerous if not properly coded...
