Get each line from textarea that contains links with PHP

This question solved my problem only until getting each line from textarea. But when I access the link (what contains in each line) with simplexml_load_file to get the data, the link started to end with unique codes:

foreach ($textAr as $line) {
    echo $line = trim($line)."<br/>"; //I trim it again just to make sure, and the result is the right link.
    echo $xml = simplexml_load_file($line)."<br/>"; //code like %3Cbr/%3E showed up at the end of the link
}

And the error is something like:

A PHP Error was encountered

Severity: Warning

Message: simplexml_load_file(link%3Cbr/%3E) [function.simplexml-load-file]: failed to open stream: HTTP request failed!

I replace the real link with link on the error message.

How to remove the unique codes (%3Cbr/%3E)? I've tried str_replace("%3Cbr/%3E","",$line) but it's not working.
