running BaseX 8.0 under OSX 10.6.8?
by C. M. Sperberg-McQueen 02 Dec '14

02 Dec '14

When I attempt to run the copy of BaseX 8.0 I just downloaded under OS X 10.6.8, I get the following error report, which at the moment I am having some trouble deciphering. cmsmcq$ /opt/local/BaseX-8.0/basex/bin/basexgui Exception in thread "main" java.lang.UnsupportedClassVersionError: org/basex/BaseXGUI : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) cmsmcq$ Is this telling me that BaseX requires a more recent version of Java than I currently have on this machine? Or is it something else? [Yes, I know, I should upgrade my operating system and possibly my hardware ... someday.] Thanks for any help. -- **************************************************************** * C. M.

New blog post: Origami - XQuery screen scraping with Extractors

It was already up for a while but DNS issues made my blog go missing for almost a week. Now it's back. http://xokomola.com/2014/11/18/xquery-origami-2.html The post describes how to do screen scraping using Origami extractors. I'm quite happy with the outcome. --Marc

Fold - HTTP routing library
by Marc van Grootel 01 Dec '14

01 Dec '14

Hi, I would like to announce a new library (very alpha) called Fold. https://github.com/xokomola/fold It is a an HTTP routing library which provides an alternative way to map HTTP requests to XQuery functions. In future I hope to use this together with Origami to build REST services and small web apps. My main goal of announcing this is to get feedback on how to improve this. Currently it is defined on top of RESTXQ but in future this might be handled by a Java extension. There are parts missing still and I strongly advise you not to use this for a serious project. Performance gets bad quite quickly. Performance gains may very well be possible by XQuery refactorings. I basically wrote this as a port from a couple of Clojure libraries. A bit of documentation for this library and for Origami can be found in each project's wiki. Note that I only just started these and they are not complete. I'll be working on this library over the next month to get it into a more usable shape. Happy to receive comments and improvements. --Marc

More Diacritic Questions
by Chris Yocum 01 Dec '14

01 Dec '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Everyone, I am rather confused again about diacritic handling in basex. For instance, with Full Text turned on a word like athgabáil will match both athgabail and athgabáil with "diacritics insensitive" which is what I would expect. However, if I try to match a word like cúachṡnaidm (with s with a dot above), it will not match without "diacritics sensitive" turned on in the query itself. I am rather confused why it would match in the case of athgabáil but not in the case of cúachṡnaidm. Does anyone know why this is happening and how to make it match like the other match? All the best, Chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iF4EAREIAAYFAlRyFScACgkQDjE+CSbP7HogoQD/eyQT0ioILJv3KHL1cKyNi+Ht a8s0g3Az5o6Uvnniw50A/Reyycsn8YiIY3naEOPuwKydBOUwrYKSe5fjOTqtZyXl =jycQ -----END PGP SIGNATURE-----

How to use ft:search() for querying 2 or more phrases?
by John Best 28 Nov '14

Hi BaseX Team, The subject itself is explanatory. I have following query - ft:search("Articles", ("electromagnetic waves"), map { 'mode':='Phrase' })/ancestor::Doc return $x This query searches for "electromagnetic waves" as a phrase. I want to search another phrase "electromagnetic particles" with the previous phrase. List only those Articles having both these phrases. -- Have a nice day JBest

CSV : escape character feature
by Fabrice Etanchaud 28 Nov '14

28 Nov '14

Dear all, I did not find a way to specify how to escape quotes when importing a csv file with quotes=yes. Here is an example : "12345"|"TOTO LE HERO"|"Toto le héro 3 \"A'' LP"|"67"|"8051"|"4000"|"XX"|""|"LU"|""|""|"ITE"|""||"GB"|""|"20.10" where quotes are escaped with a leading \ (the '' after the A are two single quotes). But it seems BaseX detects quote quote ("") as escaped quote. Could it be possible to have in the future an option to override the default behavior ? Best regards, Fabrice Etanchaud Questel/Orbit

unexpected behaviour
by Rob Stapper 27 Nov '14

27 Nov '14

Hi, I'm playing with the new XQuery 3.1 functions amongst which the JSON-serilization. I would expect all three snippets below to result in the same output but all three give a different result. Snippet 1: ======= declare option output:method 'json'; serialize( <a>test</a> ) Snippet 2: ======= serialize( <a>test</a> , map{ 'method' : 'json'} ) Snippet 3: ======= declare option output:method 'json'; serialize( <a>test</a> , map{ 'method' : 'json'} ) If I do the same with XML-serilization than all three results are the same. Are my expectations correct in this? - Rob --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com
