---------------------------------------------------------------------
It's quite like this. In fact, I call {{configurationsAt(key)}}, so I get a
{{List<HierarchicalConfiguration>}} (whose elements are in fact
{{SubnodeConfiguration}}, but I can't rely on that).
I then iterate on each element to perform some attribute manipulations, and on
some elements of that list, I'd like to remove them completely from the
complete configuration.
I used to call {{clear()}} for that, but it seems that the behavior has changed
since 1.8.
I hope I'm clearer now :)

> Key: CONFIGURATION-504
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-504
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 1.8
> Reporter: Adrien CLERC
> Priority: Minor
>
> Using an XML source file, I used to call HierarchicalConfiguration.clear() on
> an object to remove it from its parent. Now, it just clear the text and the
> subnodes, but not the node itself, nor its own attribute, when the file is
> saved.
> Here is the code that works :
> {code}
> ConfigurationNode oldNode = configuration.getRootNode();
> oldNode.getParentNode().removeChild(oldNode);
> {code}
> configuration belong to a list of HierarchicalConfiguration that I obtained
> from configurationsAt. I didn't see any other way to remove a node I got from
> that method, without explicit casting to SubnodeConfiguration.
