XQuery update: multiple document nodes with the same path
by Francis Avila 10 Aug '12

10 Aug '12

I'm having trouble understanding document/collection semantics with xquery update. If a create a document and add another document to the same path, that path becomes a collection with two document nodes. However it seems to be impossible to manipulate these document nodes individually. See the following console output: > create db test Database 'test' created in 137.25 ms. > open test Database 'test' was opened in 2.15 ms. > add to test.xml <root1/> Path "test.xml" added in 19.44 ms. > add to test.xml <root2/> Path "test.xml" added in 2.57 ms. > list test Input Path Type Content-Type Size --------------------------------------- test.xml xml application/xml 2 test.xml xml application/xml 2 2 Resources. > xquery collection('test/test.xml') <root1/><root2/> Query executed in 30.84 ms. > xquery doc('test/test.xml') Stopped at line 1, column 20: [BXDB0006] Database path 'test/test.xml' must point to a single document. > xquery import module namespace functx = "http://www.functx.com"; collection('test/test.xml') ! (document-uri(.), functx:node-kind(.), .) test/test.xml document-node<root1/> test/test.xml document-node<root2/> Query executed in 29.54 ms. > xquery delete node collection('test/test.xml')[2] Query executed in 1.18 ms. > xquery import module namespace functx = "http://www.functx.com"; collection('test/test.xml') ! (document-uri(.), functx:node-kind(.), .) test/test.xml document-node<root1/> test/test.xml document-node<root2/> Query executed in 43.83 ms. > xquery delete node db:open('test','test.xml')[2] Query executed in 2.15 ms. > xquery import module namespace functx = "http://www.functx.com"; collection('test/test.xml') ! (document-uri(.), functx:node-kind(.), .) test/test.xml document-node<root1/> test/test.xml document-node<root2/> Query executed in 36.77 ms. Note that it doesn't seem possible to delete one of the document nodes, even using db:replace() > xquery db:replace('test','test.xml',collection('test/test.xml')[1]) Stopped at line 1, column 60: [BXDB0006] Database path '%' must point to a single document. I don't understand this error message, unless db:replace is internally using the path of the document-node rather than the document-node itself. > delete test.xml 2 resource(s) deleted in 36.35 ms. But I can delete both items at the same path. The way I discovered this is that I accidentally added a document to an existing path using db:add(). However, I was unable to correct the mistake and remove the documents without completely deleting the path and re-adding its members. I don't see any way to do this with a single xquery update PUL. It seems to me that this is a bug. Either xquery update expressions like 'delete node' should work on document nodes, or adding document-nodes to a path which has a document-node should be illegal and raise an error when attempted. -- Francis Avila

Hadoop with QueryProcessor
by Tiago Freitas 07 Aug '12

07 Aug '12

Hi. I'm trying to use the BaseX QueryProcessor with Hadoop to process very large XML files. I use an XmlInputFormat to split the XML files, and process each node with BaseX. I prefer to use QueryProcessor for this and not the server (each individual element is not very large and I don't want to store the input files on a BaseX server). The problem is when I use modules in the query, BaseX can't open the module files in the distributed filesystem. I get "[XQST0059] Could not retrieve module …". I'm passing the query using "new QueryProcessor(query_string, basex_context);", and the bind method for the input. Is there a way to include the module programmatically so the QueryProcessor doesn't try to open the xquery file? Maybe with org.basex.query.util.pkg.ModuleLoader or QueryContext.module but I din't figure how to do it yet. Regards

Hi, I'd like to pick up that topic about clustering and high availability. I found a message from October 2011, you mentioned that there are a couple students working on that topic. Any updates? Maybe they could describe the approaches? That would be awesome. Have a good weekend. Philipp

What is the easiest approach to edit data in a browser and have that data stored as xml in basex
by Alex Muir 01 Aug '12

01 Aug '12

Hi, So I've got a client interested to create a dataset of music information such as artist, track name, album release year... and store that in XML. Non technical users would need to view and edit the music info in a web interface and the data would be stored in XML. I was looking at Typo3 which seems to be able to work with basex. I wonder what is the easiest approach to edit data in a browser and have that data stored as xml in basex? What are CMS solutions that work with basex? Is typo3 a good solution? Regards -- - Alex G.
