[jira] Reopened: (CONFIGURATION-335) XMLConfiguration: Can't disable attribute splitting

Oliver Heger reopened CONFIGURATION-335:
----------------------------------------


So I was too quick when closing this ticket.

The attribute splitting functionality was added because there is a mismatch between the configuration API and the capabilities provided by XML: the configuration API allows adding multiple values to an attribute while XML only supports a single value. For instance, you can have something like this:

{code}
config.addProperty("element[@attr]", "value1");
config.addProperty("element[@attr]", "value2");
{code}

When storing such a configuration, how should the multiple values of the attribute be treated so that the file can be loaded again and the resulting configuration is not changed? Because the problem is inherent there is so far no possibility of switching off this feature.

It might make sense to introduce a flag for turning off this mechanism. Can you give an example (other than that with whitespace) where this attribute splitting functionality caused undesired behavior?

> My XML configuration has the following attribute:
> <some-element some-attribute="&#x0A;&#x0D;" />
> But XML Configuration is trying to split this string and trims it after splitting. I don't need this behaviour, but setting setDelimiterParsingDisabled() just changing delimeter to "|" and not disables attribute trimming.
> Need either to disable trimming/splitting if setDelimiterParsingDisabled() is set to TRUE (incompatible change), or add something like setParseAttributesAsIs() that will prevent attributes to be trimmed and splitted
