             Summary: The OR operator works incorrectly in XPathEntityProcessor
                 Key: SOLR-5086
                 URL: https://issues.apache.org/jira/browse/SOLR-5086
             Project: Solr
          Issue Type: Bug
          Components: contrib - DataImportHandler
    Affects Versions: 4.4
            Reporter: shenzhuxi


I's trying to use DataImportHandler to index RSS/ATOM feed and find bizarre behaviours of the OR operator in XPathEntityProcessor. 
Here is the configuration.  
<?xml version="1.0" encoding="UTF-8"?>
<dataConfig>
  <dataSource type="FileDataSource"/>
  <document>
    <entity name="rss" processor="FileListEntityProcessor" baseDir="${solr.solr.home}/feed/rss" fileName="^.*\.xml$" recursive="true" rootEntity="false" dataSource="null">
      <entity name="feed" url="${rss.fileAbsolutePath}" processor="XPathEntityProcessor" forEach="/rss/channel/item|/feed/entry" transformer="DateFormatTransformer">
        <field column="link" xpath="/rss/channel/item/link|/feed/entry/link/@href"/>
      </entity>
    </entity>
  </document>
</dataConfig>

The first OR operator in "/rss/channel/item|/feed/entry" works correctly. 
But the second one in "/rss/channel/item/link|/feed/entry/link/@href" doesn't work. 
If I rewrite it to either "/rss/channel/item/link" or "/feed/entry/link/@href", it works correctly.
