[jira] Commented: (JCR-860) Add relative path parameter to rep:excerpt()

["Marcel Reutegger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12490711 ] 

Marcel Reutegger commented on JCR-860:
--------------------------------------

Committed initial support in query result row. Proper support for this feature also requires to changes to the query parsers. With just this change the excerpt function in the query statement keeps unchanged (without a parameter), but the result row recognizes a parameter for the rep:excerpt() column.

E.g. after executing the query:

//element(*, nt:file)[jcr:contains(jcr:content, 'foo')]/rep:excerpt()

One can now get an excerpt from the jcr:content node even though the result nodes are of type nt:file:

Row row = ...
Value excerpt = row.getValue("rep:excerpt(jcr:content)");

> This allows one to create an excerpt not just for the node associated with a result node, but also for a node relative to the result node.
