[ http://issues.apache.org/jira/browse/DERBY-688?page=comments#action_12429876 ] Bryan Pendleton commented on DERBY-688: ---------------------------------------
Merged d688_phase6_v1.patch to 10.2. Merge was clean and build and test runs were uneventful. Committed to subversion as revision 433854. > Enhancements to XML functionality to move toward XPath/XQuery support... > ------------------------------------------------------------------------ > > Key: DERBY-688 > URL: http://issues.apache.org/jira/browse/DERBY-688 > Project: Derby > Issue Type: Improvement > Components: JDBC, SQL > Reporter: A B > Assigned To: A B > Priority: Minor > Attachments: d688_phase1_v1.patch, d688_phase1_v1.stat, > d688_phase1_v2.patch, d688_phase1_v3.patch, d688_phase2_v1_code.patch, > d688_phase2_v1_tests.patch, d688_phase2_v2_tests.patch, > d688_phase2_v3_tests.patch, d688_phase3_v1_code.patch, > d688_phase3_v1_tests.patch, d688_phase4_v1.patch, d688_phase4_v2.patch, > d688_phase5_v1.patch, d688_phase6_v1.patch, derbyXMLSpec.html > > > As of DERBY-334, Derby has some very basic support for XML that consists of > an XML datatype and three operators (XMLPARSE, XMLSERIALIZE, and XMLEXISTS). > I would like to enhance this existing functionality and, by doing so, help to > move Derby incrementally toward a more usable and more complete XPath/XQuery > solution (with emphasis on "incrementally"). > I have attached to this issue a document describing the particular changes > that I am looking to make. At a high level, they consist of: > 1) Making it easier to use the XML operators and datatype from within JDBC > (ex. by implicit parsing/serialization of XML values). > 2) Adding a new operator, XMLQUERY, to allow a user to retrieve the results > of an XPath expression (instead of just determining whether or not the > expression evaluates to an empty sequence, which is what XMLEXISTS does). > 3) Making changes to the existing operators to line them up with the SQL/XML > 2005 specification, and also to take steps toward my eventual hope of having > support for XQuery (as opposed to just XPath) in Derby. > If anyone has time and interest enough to look at the document and provide > feedback, that'd be great... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
