[jira] [Commented] (CONFIGURATION-703) xml:space="preserve" does not handle blank strings properly

["Oliver Heger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16498390#comment-16498390 ] 

Oliver Heger commented on CONFIGURATION-703:
--------------------------------------------

To be honest, I do not remember why it has been implemented this way. What you say sounds logic, and I also do not see a reason why an element with attributes should not be able to preserve its spaces. How do the tests react when this is changed?

> When using XMLConfiguration 2, tags containing only white spaces are not handled properly when xml:space="preserve" is set.  'null' is returned instead of the actual spaces.  To reproduce:
>  
> {code:java}
> XMLConfiguration xml = new BasicConfigurationBuilder<>(
>         XMLConfiguration.class).configure(
>             new Parameters().xml()).getConfiguration();
> FileHandler fh = new FileHandler(xml);
> fh.load(new StringReader("<test xml:space=\"preserve\">    </test>"));
> System.out.println("TEST: '" + xml.getString("") + "'");
> // Outputs   -> TEST: 'null'
> // Should be -> TEST: '    '
> {code}
