Fergus McMenemie commented on SOLR-1437:
----------------------------------------
Making good progress! The //expression and its testcase is done and appear to
work well. I would have submitted a patch already except that having only
altered "XPathRecordReader.java" I am now trying to get "ant clean test" to
stop failing in org.apache.solr.handler.dataimport.TestErrorHandling.
Also while I do not yet have a total grasp of the code I think it is possible
to have XPathRecordReader.java only return fields which are children of the
forEach expression when a record is emitted. I consider this desirable and
would like to press ahead with this extra change; are there other views?
Having established that "Set<String> valuesAddedinThisFrame" and
"Stack<Set<String>> stack", in Node are only used for clearing up after a
record has been emitted. I am now pondering the purpose of the HashSet
childrenFound and putNulls. Any suggestions?
Lastly what are the chances of this making the 1.4 release?
