[Biojava-l] unexpected behavior in StAX, StringElementHandlerBase

[Michael L. Heuer]

All,

Perhaps I'm making an incorrect assumption, but shouldn't a String
element handler return the string value of just the current element?  I'm
seeing a concatenation of all the values:

 [java] There was 1 failure:
 [java] 1) testStringElementHandlerBase(ConfusedStAXHandlerTest) "expected:<d> but was:<abcd>"
