Oliver Heger commented on CONFIGURATION-703:
--------------------------------------------
Thanks for this report.
>From the unit tests of {{XMLConfiguration}} I expect that the handling of the
>of the _xml:space_ attribute should work in principle. Your case is somewhat
>special as it applies this attribute to the rool element and does not have any
>other elements in the XML document. So the problem could be specific to this
>constellation.
Did you test with other documents containing multiple elements? (Just to rule
out that there is a general problem.)
After applying your fix, do the unit tests still pass?
> xml:space="preserve" does not handle blank strings properly

> Key: CONFIGURATION-703
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-703
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 2.2
> Reporter: Pascal Essiembre
> 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}
>
