["Shalin Shekhar Mangar (JIRA)" <ji...@apache.org>]

Shalin Shekhar Mangar resolved SOLR-5086.
-----------------------------------------

    Resolution: Not A Problem

The XPathEntityProcessor does not support the OR operator in field xpaths. The OR operator is supported only in the "forEach" attribute of entity.

See the supported xpath types here:

> 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.
