Concurrency
by Rainer Klute 06 Nov '12

06 Nov '12

I have two independent databases A and B in the same context and would like to access them concurrently. To be precise: I want to read from A while writing to B. However, I seem to run into all kinds of [b]locking problems, i.e. reading from A blocks while writing to B. Is this a bug or a feature? How can I circumvent this? Would using two separate contexts be the only alternative or is there something more sophisticated? -- Best regards Rainer Klute

Newbie Question - DOCTYPE declarations
by Roy MacLean 06 Nov '12

06 Nov '12

Hi, How (if at all) can I preserve the DOCTYPE declarations in the XML documents loaded into a database. I've read the documentation pages on Parsers and Catalogs, but I can't see what allows me to do this. My editor accesses the files via WebDAV ok, but it needs the DOCTYPE for further processing.

best practices questions
by Michael Mendez 06 Nov '12

06 Nov '12

I have a db composed of several sub folders, each containing xml files that represent a person's full record from an outside source. Treating the aggregated folders as a single system has allowed us to full text all of our data at once, which has been a great improvement over the first generation of our system. As I look to move beyond testing, I now need to implement the ability to update the existing records and include information that extends beyond the outside source's. Is it better industry practice with xml based systems to a) append all the new information to the original xml, giving me one file with a full record for that person or b) create an additional sub folder or separate db with reviews and extra data, referencing the ID of their file from the outside source, isolating things like reviews as separate entities in the system, and keeping the original record intact? I am leaning towards method a, as it will result in less queries and relational style effort to assemble complete records. However I am wondering if option b would be better, as when I pull updates from our outside sources I could simply drop/replace the original record if the time stamp has changed, without losing our internally generated data on that person. Ultimately, I have been trying to figure out a way to compare and update easily, as each outside source provides a different format, and part of the appeal of transitioning to xml was to avoid heavy customization each time a new source was added or an existing service changed it's output. I don't want to write update algorithms for each service tailored for particular tags if there is a way to have it match on it's own. Thank you for your thoughts, Mike

Installation on mochahost
by pw＠themail.co.uk 06 Nov '12

06 Nov '12

Hello List I am wanting to install basex on a mochahost web service (http://http://www.mochahost.com) with a shared JVM The service provides a WEB-INF folder to which anything with the url {site}/servlet/ is directed, and there is a class and lib directory in WEB-INF I have tried to install by expanding the war file and putting the classes and libs in the respective subdirectories of WEB-INF and putting web.xml in the WEB-INF directory itself, but am not having any joy in accessing the rest interface. I would appreciate some constructive suggestions Many thanks Peter

jquery script only partly working
by France Baril 06 Nov '12

06 Nov '12

Hi, I am displaying html from transformed content. *module namespace **jq* = " http://www.architextus.com/xquery/library/how2_jquery"; *declare namespace **rest*="http://exquery.org/ns/restxq"; *declare* %rest:path("/testjquery") %rest:GET *function* *jq:test*() *as **node*(){ *let **$html* := <html *xmlns*=*"http://www.w3.org/1999/xhtml"*> <head> <title>Testing JQuery</title> <script *src*=*"http://code.jquery.com/jquery-latest.js"* *type*=* "text/javascript"*></script> </head> <body> <div> <p><input *id*=*"helpful-yes4"* *name*=*"helpful"* *type*=*"radio"* ></input><span>Yes</span> <input *id*=*"helpful-no4"* *name*=*"helpful"* *type*=*"radio"* ></input><span>No</span></p> <p>Here is a paragraph</p> <div *id*=*"t1"*>Test redirectire.</div> <script *type*=*"text/javascript"*> $("#helpful-no4").click(function ( event ) { $("#t1").show();}); $("#helpful-yes4").click(function ( event ) { $("#t1").hide();}); </script> </div> </body> </html> *return **$html* }; I access content with: http://localhost:8984/restxq/testjquery The jquery does not work. If I save the result with a right-click in the browser, it saves as .xml. Jquery doesn't work either. If I rename the saved file .html. It works. Is there anything I can do for the browser to think what it gets is .html when displaying dynamic content? Note: My html is not as simple as the one above. It is generated from an .xsl that actually says <xsl:output method="html"/>. The result however is the same. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

an application working with BaseX : mysimplegrid
by Yoann Maingon 06 Nov '12

06 Nov '12

Hi folks, When I started using BaseX, I always had Issues understanding what everyone was using it for. So now that we've built our product mysimplegrid, I just wanted to share it with you. It's a data-model driven spreadsheet which offers a solution between classic spreadsheet and databases management systems. It's designed for people actually using Excel for data management with a low need for calculation. We just launched our website, you can sign up for our beta access which should occur by the end of the month. I'll be happy to share how we've used basex and why we used this solution, visit www.mysimplegrid.com There are 2 vidéos, one explaining the concept and another one at the bottom of the home page showing the product itself. -- Yoann Maingon mydatalinx 0664324966

Hi, Using restxq, do all queries have to begin with db:open('web_app_db')//myquery/here , or can the database be declared? Or set as default somewhere? Thanks, Colin

Database housekeeping for newbies
by Sam Eklund 05 Nov '12

05 Nov '12

Hey all! I am considering BaseX to hold event information for a broadcast graphics play out system. This system gets a lot of event data from the planning system. Each segment can have up to 12 events, and a day in a typical commercial tv-channel has about 120-160 segments. The commercial breaks not included. Every time a full day of programming is made for a channel, an xml file is produced containing a lot of (badly formatted) EVENT nodes, below a typical "coming next" event: <EVENT IDdeko="109213416" DATE="2012-09-21" CHANNEL_ID="123" VIDEOFORMAT="2"> <SCENARIO ID="29"> <METADATA pos="0" value="00:20"/> <METADATA pos="1" value="The Godfather pt III"/> <METADATA pos="2" value="American drama from 1990 with Al Pacino and Andy Garcia"/> </SCENARIO> </EVENT> I have manually created a database from one of these export xml files and manged to call a BaseXClient dll that I compiled from your examples to retrieve data from the database. All is well with that. Now to my question, since I'm not really familiar with databases in general... Is it possible to set up a "watch folder" for the incoming xml files that will add them to a specified database or would I have to create an application for this? The second question is about housekeeping, since we are handling about 20 channels with this database, the number of events in the database will increase quite fast. Is it possible to specify an xpath search that would match all events with a date more than X days back in time and delete them from the database, i.e delete data from the database without calling the exact file the data was imported with? Best regards SamTheSwede Stockholm
