	function selectElementContents(el) {
		// Copy textarea, pre, div, etc.
		
		if (document.body.createTextRange) {
			// IE 
			var textRange = document.body.createTextRange();
			textRange.moveToElementText(el);
			textRange.select();
			textRange.execCommand("Copy");
		} else if (window.getSelection && document.createRange) {
			// non-IE
			var range = document.createRange();
			range.selectNodeContents(el);
			var sel = window.getSelection();
			sel.removeAllRanges();
			sel.addRange(range); 
			
			try {
				var successful = document.execCommand('copy');
				var msg = successful ? 'successful' : 'unsuccessful';
				console.log('Copy command was ' + msg);  
			} catch(err) {
				console.log('Oops, unable to copy');
			}
		}
	} // end function selectElementContents(el) 
	
	function make_copy_button(el) {
		var botaodecopiar = document.getElementById('botaodecopiar1');
		botaodecopiar.onclick = function() { selectElementContents(el); };
		
		if (document.queryCommandSupported("copy") || parseInt(navigator.userAgent.match(/Chrom(e|ium)\/([0-9]+)\./)[2]) >= 42) {

			botaodecopiar.value = "Copy to Clipboard";
		} else {
			// Select only for Safari and older Chrome, Firefox and Opera
			botaodecopiar.value = "Select All (then press CTRL+C to Copy)";
		}
	}
	
	var elem = document.getElementById("markup");
	var elem2 = document.getElementById("markup2");
	make_copy_button(elem2);

Não deu com span, mas obrigado pela ajuda :wink:

Já encontrei a solução, era só colocar CSS no elemento que não quero que passe a seleção:
-moz-user-select: -moz-none;
-khtml-user-select: none;
-webkit-user-select: none;
-ms-user-select: none;
user-select: none;

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.scene.layout.HBoxBuilder;
import javafx.stage.Stage;

public class SpacingDemo extends Application {
public static void main(String[] args) {
launch(args);
}

@Override
public void start(Stage stage) {
    stage.setTitle("Spacing demo");

    Button btnSave = new Button("Save");
    Button btnDelete = new Button("Delete");
    HBox hBox = HBoxBuilder.create()
            .spacing(30.0) //In case you are using HBoxBuilder
            .padding(new Insets(5, 5, 5, 5))
            .children(btnSave, btnDelete)
            .build();

    hBox.setSpacing(30.0); //In your case

    stage.setScene(new Scene(hBox, 320, 240));
    stage.show();
}

}
