Subject [jira] Commented: (JCR-247) Child axis support for XPath predicates
Date Sat, 10 Feb 2007 00:58:06 GMT

    [ https://issues.apache.org/jira/browse/JCR-247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12471888

Randy Simon commented on JCR-247:

This feature has saved me.  However, I think there may still be some issues.

For example,
I want to find the root of a node tree that contains a node with a specified id.  The child
node may be n layers deep in the node tree.  In my specific case, I know how deep it is so

//element(*, my:foo)[bar/*/*/*/*/@jcr:uuid = 'abc'] 

finds the node of type my:foo that contains the child node with id 'abc'.

Now, I would like to generalize this so I thought i could simply do the following.
//element(*, my:foo)[bar//*/@jcr:uuid = 'abc'] 

but this does not work.

Is this supported?  Should this bug be re-opened? Thanks.

Support for the child axis would be a nice addition.
