importing library with alternative namespace
by Jan Vlčinský (CAD) 24 Feb '12

24 Feb '12

Hi I am really happy to see an option to import xquery library - it shall let me organize my code much better. When testing sample from wiki: http://docs.basex.org/wiki/Packaging I tried to modify proposed instruction: import module namespace functx="http://www.functx.com"; into this, using alternative namespace: import module namespace functxyz="http://www.functx.com"; The import worked well, but when calling functxyz:capitalize-first("test") I got result: Error: [FONS0004] No namespace declared for prefix 'functx'. Questions: Is this ok, that I am forced to use assigned namespace, or is this just some bug in the library I have teested? Or bug in BaseX? With best regards Jan *Ing.

Announcing Nxdb - A .NET Binding for BaseX Focused On Embedded XML Databases
by Dave Glick 23 Feb '12

23 Feb '12

Hi all, I'd like to announce Nxdb, a pure .NET binding for BaseX that is focused primarily on using BaseX as an embedded XML database. It can run under Mono and does not require any Java or JVM support. It is the culmination of several years of work with BaseX on the .NET platform in multiple commercial projects. It introduces an entirely new API focused on direct database node manipulation as well as several other features intended to make the embedded database use case easier. The project portal is here: https://dracorp.assembla.com/spaces/nxdb Please feel free to give it a try and let me know what you think. I'm still working out the best way to document, distribute, etc. so suggestions in that area would be helpful as well. I'm also very interested in ideas on what should be added or improved next. Thanks, Dave

SQL module in 7.1.1
by Mike Cobo 23 Feb '12

23 Feb '12

Hi, I just installed the new version 7.1.1 and it doesn't recognize the SQL functions. The error is: "Unknown function sql:init()" on the BaseX GUI. With the older version I didn't get this error. Do I need to install a package now in order to use the SQL functions now? Regards, Mike

Load files to database
by Anh Thuấn 23 Feb '12

23 Feb '12

Hi, baseX team. I have some problems of loading xml files into the database of BaseX. I am comparing the time to load xml files into database, there are 2 ways to load: Loading all the folder into the database and Loading each file into the database. The time to load all the folder and the time to load each file have a big difference. The time to load all the folder into the datebase is 84ms, whereas the time to load each file into the database is 912 ms. I have written the 2 ways to load in C#. The following code is to load all the folder into the datebase: private void CreateDBAndLoadDirectory(string directoryPath) { this.contextDirectory = new Context(); this.serverDirectory = new org.basex.BaseXServer(this.contextDirectory); Set.execute("createfilter", "*" + this.fileExtension, this.contextDirectory); Set.execute("CACHEQUERY", true, this.contextDirectory); Set.execute("SERIALIZE", false, this.contextDirectory); Set.execute("CHOP", true, this.contextDirectory); Set.execute("DBPATH", this.dbPath, this.contextDirectory); new CreateDB(this.dbDirectory, directoryPath).execute(this.contextDirectory); } And the following code is to load each file into the database: private void CreateDBAndLoadFiles(string directoryPath) { this.contextFile = new Context(); this.serverFile = new org.basex.BaseXServer(this.contextFile); Set.execute("CACHEQUERY", true, this.contextFile); Set.execute("SERIALIZE", false, this.contextFile); Set.execute("CHOP", true, this.contextFile); Set.execute("DBPATH", this.dbPath, this.contextFile); new CreateDB(this.dbFile).execute(this.contextFile); string[] fileList = Directory.GetFiles(directoryPath, "*" + this.fileExtension,SearchOption.AllDirectories); foreach (string fileName in fileList) { string path = fileName.Substring(this.otxPath.Length + 1); new Add(path, fileName).execute(this.contextFile); new Optimize().execute(this.contextFile); } } I don't know if I have made mistakes in these codes or not? I want to ask about the fastest way to load each file into the database.

Is it true that basex can output HTML, http://docs.basex.org/wiki/Serialization but not read it back in? http://docs.basex.org/wiki/Parsers

Re: [basex-talk] GUI stops displaying results when query is too large
by Andy Bunce 22 Feb '12

22 Feb '12

I have seen something similar, maybe it is your case: If I have a database open and I have an updating query in the editor or just referenced from an import module then when I execute the result is displayed for a moment then immediately replaced by the open db display. e.g. import module namespace state="apb.state"; (: this has an update function :) 2 My workaround is just to work with no open db. /Andy > > When the size of the submitted query gets too large, GUI functionality > stops working: Results stop being highlighted in the tree or displayed in > the "text" window (which instead always displays the entire document).

7.1.1 - GUI stops displaying results when query is too large
by Charles Duffy 21 Feb '12

21 Feb '12

Howdy -- I've been working on an XQuery function library in the GUI editor (which is great!), and putting actual queries in the bottom. This library has been growing in size (currently about 16K), and therein lies the problem: When the size of the submitted query gets too large, GUI functionality stops working: Results stop being highlighted in the tree or displayed in the "text" window (which instead always displays the entire document). I can run the exact same XQuery file through basexclient or a REST query and everything works perfectly, so this appears to be strictly a GUI concern. If I move enough text to the clipboard, or comment out part of the buffer, everything works perfectly again.

Marking up util:time output
by Charles Duffy 21 Feb '12

21 Feb '12

Howdy -- If I'm running a query which includes a number of util:time calls against different data, how can I know which one is doing what given that execution order is undefined? Is there another function I can use to emit an arbitrary value to the "info view"? If not, an optional parameter providing a string to tag profiling times with would be convenient. Thanks!

Why does OPTIMIZE ALL require an open database?
by Charles Duffy 21 Feb '12

21 Feb '12

If OPTIMIZE ALL iterates over all available databases, why does it fail if there isn't one open when invoked? Or am I misunderstanding what it does?
