Oliver Heger commented on CONFIGURATION-366:
--------------------------------------------
I don't know your exact use case, but maybe you can rely on the fact that an
empty element has an empty string as value. So you could do something like the
following:
{code}
for(Iterator it = raspConfigurationFile.getKeys(csXPath); it.hasNext())
{
String value = raspConfigurationFile.getString(it.next());
if(value.length() > 0)
{
// do something with the value
}
}
{code}
> XMLConfiguration.getKeys() broken

> XMLConfiguration.getKeys(String prefix) returns iterator with the string
> argument "prefix", when the xpath specified has no sub elements. The
> XPathExpressionEngine has been used as Expression engine.
> Version 1.3 does not have this problem. Here an empty Iterator is returned.
