Alex Selg created CONFIGURATION-500:
---------------------------------------
Summary: Attributes in xml config should apply to all entries of a
list
Key: CONFIGURATION-500
URL: https://issues.apache.org/jira/browse/CONFIGURATION-500
Project: Commons Configuration
Issue Type: Improvement
Components: Expression engine
Affects Versions: 1.8
Environment: Linux, Windows
Reporter: Alex Selg
If you have an XML configuration with lists and attributes like this:
{code:xml}
<configuration>
<someStrings environment="test">str1,str2,str3</someStrings>
<someStrings environment="prod">str4,str5,str6</someStrings>
</configuration>
{code}
and if you have a different implementation of the DefaultExpressionEngine which
implements the query() methode to check these attributes
{code}
List<ConfigurationNode> queryResults = super.query(root, key);
for (ConfigurationNode queryResult : queryResults) {
attributes = queryResult.getAttributes();
...
}
{code}
than you'll only get the attributes for the first node of the list - the
subsequent nodes don't have any attributes set.
So for "str1" I'll get the attribute environment="test", for "str2"
and "str3" I'll get no attributes.
Oliver H. pointed out that this is the intended behaviour
(http://mail-archives.apache.org/mod_mbox/commons-user/201205.mbox/browser).
I think it would be more straightforward assigning attributes to all nodes of a
list. Otherwise the list feature seems incomlete to me.
Especially if your lists are a bit longish it would be very nice to avoid
repeating tags in your config.xml.
