BaseX 7.1, XMLPrague, Review
by Christian Grün 16 Jan '12

16 Jan '12

Hi all, thanks for your continuous feedback and support (such as contributing to our Wiki, to our code base, or giving feedback on this list). For those who have noticed that BaseX 7.1 was announced for the middle of January: we will be postponing the release a little and align it with the upcoming XMLPrague conference. Next, our XMLPrague BaseX Meetup has now been confirmed. It will take place on Feb 10 (Friday) from 09:00-11:30 am. Please find more information on the XMLPrague and on our homepage soon [1]. Last but not least, we are glad to report that 2011 was a very successful year for BaseX, both regarding the commercial branch as well as the open source development! Rest assured that 2012 will get exciting again.. Stay tuned, Christian [1] http://www.xmlprague.cz/

Re: [basex-talk] URI for xquery : collection()
by Christian Grün 16 Jan '12

Dear Francesco, in oXygen, if your databases are locally stored, you can directly address the database you are working with by using e.g. the db:open() function: for $text in db:open("lettres_20120109", "Info2085.xml")/tei:TEI .... Currently, however, you'lll not be able to traverse collections on a remote server via oXygen; in this case, you'll have to resort to one of the other APIs/tools, or wait for an updated version of our XQJ implementation, which will also support remote connections. Hope this helps, more questions are welcome, Christian On Mon, Jan 16, 2012 at 7:12 PM, Francesco Beretta <Francesco.Beretta(a)ish-lyon.cnrs.fr> wrote: > Hi, > > as a beginner with BaseX, I'm trying to execute a xquery via an OxygenXML > transformation scenario on an external server. > > I created the data source and connection as explained in the BaseX wiki. > > The xquery functions well on a single document, with following connection > syntax : > > "for $text in > doc('http://admin:*****@10.211.55.5:8984/webdav/lettres_20120109/Info2085.xml')/tei:TEI > ..." > > But it doesn't work against the whole database if I write : > "for $text in > collection('http://admin:*****@10.211.55.5:8984/webdav/lettres_20120109')/tei:TEI > ...". > > It works fine if I use the baseX GUI on the 10.211.55.5 server (which > becomes a localhost) : > "for $text in collection('lettres_20120109')/tei:TEI" > > What I'm doing wrong ? > > Many thanks and greetings > > Francesco Beretta

Re: [basex-talk] line number and column
by Dave Glick 15 Jan '12

I had a similar requirement a while back and ended up solving it in two ways: The first attempt I wrote a routine that would take a node and scan for all text nodes along the preceding axis. I would then add the length of each text node to a counter (I wanted offset), but counting new lines shouldn't be much different. I used the API, but I don't think it would be too tough to write an XQuery expression or function that does the same thing. Alternatively you could use the BaseX functionality to call Java code from XQuery to write it up in code. This worked okay in isolated cases, but I needed the info very frequently (I was writing a text editor backed by XML, so I was constantly getting offsets for the caret) and scanning the preceding axis each time took too long. I ended up going through every node in sequence for a new document and caching the information. The idea was the same though - every time I hit a text node, I incremented a counter and used the value for following nodes (until I hit another text node). Not sure if that helps - hopefully it does...

xquerydoc support for BaseX
by Andy Bunce 14 Jan '12

14 Jan '12

Hi, The https://github.com/xquery/xquerydoc project is looking like a good tool to generate Xquery documentation. Currently it is failing on some BaseX extensions. See https://github.com/xquery/xquerydoc/issues/6#issuecomment-3491893. Is there a EBNF source for the map module syntax available somewhere? /Andy

line number and column
by Anders Hessellund 14 Jan '12

14 Jan '12

Hi, we are experimenting with BaseX as a database for a large set of local XML files (3000-4000). When we query for individual elements and attributes in this portfolio of XML documents, is there any way to get location information about concrete elements and attributes. Specifically, we need to know filename, line number and column of element (start tags) and attributes. Is this possible? And if so, how? Thanks, Anders

RegExp bug
by Mark Boon 09 Jan '12

09 Jan '12

It's been a while since I did anything with BaseX. The last version I used was BaseX 6.5. Today I downloaded the latest version 7.0.2 and ran into a problem when trying to revive an old project. I get messages saying " [FORX0002] Invalid escape character: '\b'". Since the use of \b is rather essential to my project I had little choice but to investigate, so I retrieved the BaseX source code to see if I could determine the problem. I found the following in RegEx.java, line 88: if("0123456789cCdDniIrsStwW|.-^$?*+{}()[]\\".indexOf(c) == -1) REGESC.thrw(input, c); I believe that's a mistake and should include 'b' and read: if("0123456789bcCdDniIrsStwW|.-^$?*+{}()[]\\".indexOf(c) == -1) REGESC.thrw(input, c); When I make that modification my program works again as before. There may be more missing? I'm not especially a RegExp expert. And I'd like to make sure this modification didn't inadvertantly break something else that I just haven't noticed yet. Mark Boon

Spatial XQuery?
by Schildmann, Ingo 09 Jan '12

09 Jan '12

Hi, Our company evaluates BaseX for our project. A new requirement is to show spatial data with a geographic information system. Are there any plans for a spatial xquery module for querying GML like the (experimental) module in eXist? http://exist-db.org/extensions.html#module_spatial Regards, Ingo Dr. Karb Informationstechnologien Im Wolfer 10 70599 Stuttgart Tel.: 0711 - 4 51 24 - 70 Fax: 0711 - 4 51 24 - 55 Web: http://www.karb.de <http://www.karb.de/> Mail: schildmann(a)karb.de <mailto:schildmann@karb.de> Skype: ischildmann
