Christian Uldall Pedersen commented on CONFIGURATION-366:
---------------------------------------------------------
What I find a bit peculiar is that getKeys returns the following two elements:
//configurationsecti...@*="DocumentTypeCollectionConfig"]/DocumentTypes/DocumentTypeConfig[1]/CustomHeaderConfiguration/XPaths/Test
//configurationsecti...@*="DocumentTypeCollectionConfig"]/DocumentTypes/DocumentTypeConfig[1]/CustomHeaderConfiguration/XPaths/Ber
On this XML (Config_1):
<XPaths>
<Test>Data</Test>
<Ber>Data2</Ber>
</XPaths>
And:
//configurationsecti...@*="DocumentTypeCollectionConfig"]/DocumentTypes/DocumentTypeConfig[1]/CustomHeaderConfiguration/XPaths
On this XML (Config_2):
<XPaths>
</XPaths>
So the logic is that if there are sub elements then return those, if no sub
elements then return parent element?

> 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.
