Subject [jira] [Commented] (CONFIGURATION-703) xml:space="preserve" does not handle blank strings properly
Date Sun, 27 May 2018 16:23:00 GMT

    [ https://issues.apache.org/jira/browse/CONFIGURATION-703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16492082#comment-16492082

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

Oh, found the reason: The _determineValue()_ method in {{XMLConfiguration}} handles elements
that have only whitespace as content in a special way. Space is only preserved if the element
has some other text content rather than exclusively whitespace. This was obviously implemented
this way to not change behavior and break existing code. This is of course still a problem.

>                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-703
>             Project: Commons Configuration
>          Issue Type: Bug

>            Priority: Major

> 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}
>
