XPath queries

[Michael Yin <yi...@gmail.com>]

Is there any documentation on doing xpath queries via sling?
I found this blog post, but it'd be nice if there were some official docs.

As noted in that article, the json query servlet is get by using the
"query" selector and the "json" extension. The query type is given in
the "queryType" parameter (xpath or sql) and the statement is in the
"statement" parameter.

The queries itself are standard JCR queries, see the JCR 1.0 spec [1]
[2], the jackrabbit mailing lists or some googling for eg. "jcr
xpath".
