If you want to skip all of the elements which don't have the achieved element with a value of 1, you can use the continue statement to skip the rest of your processing and move on the the next item in the list.

foreach ( $xml11->achievements->children() as $items ){
    if ( $items->achieved != 1 ) continue;
    // ... rest of your code
}
