Is there a way to parse html file located in local hard drive? Http module of xquery is fantastic, you can retrieve any url content. but I have already html file locally and need to parse. Can I do it http://docs.basex.org/wiki/HTTP_Module I would like to do this successfully: let $l := http:send-request(<http:request method='get' status-only='false'/>, 'file:///D:/tmp/b000187585.htm') return $l Thanks Erol Akarsu On Tue, May 1, 2012 at 5:24 PM, Christian Grün <christian.gruen(a)gmail.com>wrote: > ...by the way, you can also use our own map implementation to store > key/value pairs in XQuery: > > http://docs.basex.org/wiki/Map_Module > ___________________________ > > On Tue, May 1, 2012 at 11:22 PM, Christian Grün > <christian.gruen(a)gmail.com> wrote: > >> I am having problem in making new of Properties object. > > > > Thanks; this has been fixed in the latest snapshot, which I've just > uploaded. > > Christian > > __________________________________ > > > >> Query: declare namespace system = "java:java.lang.System"; > >> declare namespace fis = "java:java.io.FileInputStream"; > >> declare namespace p = "java:java.util.Properties"; > >> > >> let $a := 555 > >> return <a>{(p:new ())}</a> > >> Error: Improper use?

eval evil?
by Andy Bunce 29 Apr '12

29 Apr '12

Musing on the the usefulness of actions that update the database and return something, specifically in a web server with Xforms context, and the absence of XQuery scripting. I have been playing around with things like the following: let $s:=util:eval(' let $x:=copy $c:=db:open("listman","1.xml") modify (replace value of node $c/updated with current-dateTime()) return $c return db:replace("listman","1.xml",$x) ') return db:open("listman","1.xml") This works, but is it likely to stop working in the future? Is there a better way? /Andy

Add a spatial index ?
by Haderer Nicolas 27 Apr '12

27 Apr '12

Hello I'am a phd student and i explore actually multiples no-sql solutions to store and process location data such as gml or gpx. I have already familiar with BaseX, and the combinaison XML/XQuery providing the flexibility needed for my project. However, process spatial data need spatial index such as R-tree in order to be processed efficiently. I would like to know if an implementation of spatial index into BaseX exist or are in project ? And if not, does the BaseX architecture allow to add new index easily ? Best regard Haderer Nicolas

a possible enhancement to program exit
by C. M. Sperberg-McQueen 24 Apr '12

24 Apr '12

In BaseX 7.2 just now, I pressed Command-Q to quit the program. My query had changed, so the program put up a dialog box to ask "Save changes to file?" with buttons for Yes, No, and Cancel. As I looked at the dialog box, I noticed that the query in question was not the one I had thought it was (for a project I was closing down) but a different one (the project I was intending to focus on next). So I didn't want to quit the program after all. I clicked on Cancel, expecting that my request to shut BaseX down would be canceled and BaseX would continue running with my query file still in place. But in fact BaseX exited anyway. As far as I can tell, it didn't save the query (no great loss, in this case, I think), so that Cancel effectively had the same effect as No. It's been a long time since I read anything about standard user interface idioms, so I don't want to go so far as to say that this is a bug. But it did surprise me, and so I suggest that it might be helpful to make the Cancel button in this dialog box cancel the quit action. Consider it a request for enhancement. Thanks!
