What is the proper way to check for a missing file

[burki]

This is more a question than an error.

I'm calling $xml = \FluentDOM::load($fname, 'xml', [ \FluentDOM\Loader\Options::ALLOW_FILE => true ]); on a non-existing $fname and then get a valid document with

<?xml version="1.0" encoding="UTF-8"?>

when I call $xml->saveXML().

I checked both the wiki and the source and couldn't find the proper way to catch this besides calling file_exists() or something similar on $fname before calling the loader.

It would be great if there was a way to somehow check the return-value (TRUE or FALSE) of $document->load($source, $settings[Options::LIBXML_OPTIONS]); (https://github.com/ThomasWeinert/FluentDOM/blob/master/src/FluentDOM/Loader/Supports/Libxml.php#L59) or if $document was returned as NULL when $document-load() returns FALSE (either always or through an additional loader option).

Here is no explicit handling for that.

I should implement some proper exceptions for that.

This will now throw an FileNotLoaded exception
