问题 I want to get the file extension of uploaded file in Marklogic server. I know how to get the file name. But that gives filename plus extension like new.txt. But I want only extension not the full file name. How can I get just the file extension ? 回答1: There are many methods of getting file extensions from filename. For instance you can use functx:substring-after-last($filename, '.') or other methods (fn:substring-after) of getting substring after dot. Please see: xqueryfunctions.com P.S. fn

问题 After inserting few XML records in ML8, I was able to query them using XQuery through Query Console.. Lets say following XML's are there: Say one XML contains data like: <?xml version="1.0" encoding="UTF-8"?> <Providers> <Provider> <ProviderId>1111</ProviderId> <Name>John Doe</Name> <Age>40</Age> <Country>MN</Country> </Provider> <Provider> <ProviderId>2222</ProviderId> <Name>Jane Doe</Name> <Age>42</Age> <Country>MS</Country> </Provider> </Providers> There is an option to use SQL in query

问题 I'm liking what I read about Narthex, but the bug list looks a touch scary, the reliance on a specific server install doesn't make me leap for joy, and the setup is a bit over my head. What I'd ideally like to know is whether or not I should invest time in not just trying this project out but learning how to implement it. My immediate and future needs require something like Narthex to aid in the creation of interfaces and collections of learning material, it would be in a controlled usage

问题 I am using PUT method of document rest api for inserting document but I want to validate xml document before ingestion using schema if it fails I have to report it back. How can I achieve this within Marklogic using rest api similiar to xdmp:validate() in xquery ? I have come across approach like pre-commit triggers, creating rest transformation etc..looking for your inputs. 回答1: Pre-commit triggers are more difficult to configure, and take more overhead. I'd go for a rest transform. That

问题 There are 2 collections /test/123 and test/567 I want to return the latest document of both the collections. let $a := cts:collection-match("/test/*") for $t in $ a let $latest :=( for $doc in fn:collection( $t) order by $doc//timestamp descending return $doc)[1] return fn:concat($latest//id/text(),",",$latest//timestamp/text()) Is there a better to get the latest document from the collections I want the final output of query after searching both the collection to be in descending order for

问题 I'm using the MarkLogic Java API. I'm looking for a way to set the Query Type of a StringQueryDefinition. The type should be "Value", as described in: https://docs.marklogic.com/guide/search-dev/searchdev#id_34905. Value: Match an entire literal value, such as a string or number, in a specific JSON property or XML element. By default, value queries use exact match semantics. For example, a search for 'mark' will not match 'Mark Twain'. I need this because I want my text searches to match only
