Support text() condition
- Added Antlr parsing of text() condition (as an optional additional to any query) - Implemented text-condition combined with descendants - Refactor descendants queries into using one more flexible Custom (native) Query builder - Refactor ALL cpsPath queries to now use FragmentRepositoryCpsPathQuery (custom query builder) - Refactor Antrl code to simply parsing of cpsPath and allow all combinations (no more query types, addresses CPS-436) - Minor clean up of some minor convention issues in CpsAdminServiceImplSpec.groovy (found during groovy demo) - Update .rst documentation of xPaths - Fixed incorrect matching of additional list indexes using more precise SIMILAR-TO regex in postgreSQL - Documented special chararter limitation (CPS-500) - Checked for consistent use of term 'CPS path' in documentation and error message - Included (updated) copyright in all .SQL test files Issue-ID: CPS-452 Issue-ID: CPS-436 Issue-ID: CPS-500 Signed-off-by: ToineSiebelink <toine.siebelink@est.tech> Change-Id: If422d25cafd2850d25c9a28dea16ba7a5f93dddb
