a few questions about BaseX as an embedded db
by Anders Hessellund 02 Feb '12

02 Feb '12

Hi, I am experimenting with BaseX and have so far built a little toy application that uses an embedded BaseX database. All xml-files in a certain folder, e.g., c:\myXml, is added to the database using the Create and Add commands. This works fine and I can run interesting (and efficient) queries on this. Now we get to my questions: 1. Next time I start my application, I do not want to rebuild the database so I simply connect using the Open command. How do I make sure that the BaseX representation/indexes are synched with the actual XML files in the c:\myXml folder? Does this happen automatically as a side-effect of Open or do I need to take some steps? I am particularly concerned about the case where other programs have manipulated the files when my app was shutdown. 2. Is it possible to do any parts of creating, adding, and opening concurrently? 3. Is it possible to cache results (full or partial) of XQueries? 4. Is it possible to attach schema validation? I do not mind hacking a bit. It seems like there is a SAXHandler available (new Set(Prop.INTPARSE, "false")), could I possibly override that implementation? Cheers, Anders

GUI query editor --> revert file
by Piotr Bański 26 Jan '12

26 Jan '12

Hi all, I have an feature request for the GUI editor (veeery handy for testing, thanks!): make it possible to revert files from disk. I have a file open in it that I want to update, because it got modified externally. But I can't -- not even if I open the open-file dialog and try to open it again, as if. No go, the old version sits in the editor still, and I was lucky not to overlook this fact or else I wouldn't know why it doesn't work. Thanks for considering this, and thanks for your work on BaseX, Piotr

Qualified Attributes In Root Elements
by J Gager 26 Jan '12

26 Jan '12

Dear All, I have found some odd behavior when using the db:add XQuery function with the document constructor. When the root element contains a qualified attribute, all namespaces are being dropped. For example: db:add('testing', document{ <a:Root xmlns:a="ns1" xmlns:b="ns2" a:id="test"><b:Child>Text</b:Child></a:Root> },'doc_1') will result in the following being added to the database (note the namespaces are removed): <a:Root a:id="test"> <b:Child>Text</b:Child> </a:Root> Neither of the following queries retrieves the added node: declare namespace a="ns1"; /a:Root /*:Root The only query that seems to acknowledge this node is: /* However, using a string for the document does work: db:add('testing', '<a:Root xmlns:a="ns1" xmlns:b="ns2" a:id="test"><b:Child>Text</b:Child></a:Root>', 'doc_2') but this is not desired as the content to be added may have quotes within its elements. The namespaces are also retained using the document constructor if the root node does not contain a qualified attribute: db:add('testing', document{ <a:Root xmlns:a="ns1" xmlns:b="ns2" id="test"><b:Child>Text</b:Child></a:Root> },'doc_1') Is this a bug or am I missing some special handling rules of the document constructor? Any feedback is much appreciated. Thanks, Jack Gager Metadata Technology

baseX performance with large number of small documents (are the indexes working??)
by Shahin Roboubi 25 Jan '12

25 Jan '12

I'm trying to see if I can use baseX for a project we have. We need to store a large number of small documents (about 5,000,000 where each document is 1 to 10K). I had some performance issues and searched the mailing list and found some answers like this: https://mailman.uni-konstanz.de/pipermail/basex-talk/2012-January/002478.ht… This suggests I should be able to get good performance (query times that are around ~100ms or so). I'm running this on a linux server with fast disks and 24 GB of RAM (4 GB for JVM). By the way, I'm doing the queries through the baseX GUI... not sure if that makes any difference. I created 3 test databases, small, medium and large. The results are shown below. All databases have full text search disabled (because I don't need it) and "Path Summary", "Text Index", "Attribute index" enabled. It seems like the indexes are not doing anything or just not working, because the query times are going up linearly (up to 5 seconds for the large database!!) with the size of the database... can someone explain what is happening/why, and how I can fix it?

referring to the database root node from a function
by Piotr Bański 25 Jan '12

25 Jan '12

Hi all, This is, I'm afraid, a basic question, that in my hasty searches I just must have missed a solution to. I would like to find a clean way of referencing the default context of my main module, where I can easily do "let $x := //whatever", but after I move this line to a function declaration. Is there any kind of database-root() function that would provide such a reference? I realise that I can pass the relevant node as one of the function's arguments, or use a doc() there with the appropriate path, or maybe even use the "declare context item" functionality that i haven't been successful in putting to work so far, but maybe there exists a much simpler way out? I'll be grateful for a hint. Thanks in advance, Piotr

python client library
by info＠arjenvanelteren.com 23 Jan '12

23 Jan '12

Hi All, I've been accessing the BaseX library from python for a while now. Unfortunately the client library for python does not provide the full client library (returning per item result and the event code) I've updated the python client library for basex. It contains: *) a small bugfix in buffered reading (plus some refactoring), *) support for iterating over the result of a query *) and watching events. If you like I can create some examples for these... I've attached the updated file. Kind regards, Arjen van Elteren

(no subject)
by Adrian Hossu 23 Jan '12

23 Jan '12

Hello all, We have an issue with performance in basex. We are using basex to manage some user generated content, which has frequent updates. Each user has his own "home" within one large xml document, and they are able to update content within their own home. Our problem is that as our number of users increased, we started to notice some major slow-downs on our server. A small update of the user's content (one or two xml nodes) sometimes results in our [flush-...] process writing about 30MB of data. I hope this makes sense. I haven't actually looked at the basex source code, so I don't know what happens during these updates, but it seems to me that the amount of data written to the disk per update is relative to our database (document) size, although the amount of data being updated remains constant. Perhaps there is an index update happening? Sorry if I'm talking nonsense because I don't really understand how basex works. So basically, I have several questions: 1) Is it a bad idea to have one single large document, which can have many frequent updates? 2) Would it be better to have a document for each user? This would result in about 1000 documents being created per day. Does basex index documents within a database, for quick retreival, and is there a limit on the number of documents that you can have in a single database? 3) if we switch to one-document-per-user, would updating these documents somehow still result in large amounts of data being written per update, even if the user's documents are very small? Or would this be a possible solution to our problem? Thank you and I hope this made sense, - Adrian

Running BaseX commands from xquery esp REPO LIST
by Andy Bunce 19 Jan '12

Hi, I using the EXPath repository and it is going well. It would be useful to me to manage the repository from Xquery, at least to get the REPO LIST result. I see Exist DB has http://demo.exist-db.org/repo/repo.xml#d5510e705 Are there any plans to add something similar to BaseX One quick, if a bit hacky, way to enable this to be built would be a new util:command("command string") e.g. util:command("get timeout") <result>TIMEOUT: 0</result> /Andy

performance question
by Cerstin Mahlow 18 Jan '12

18 Jan '12

Hi, I would like to set up a collection of TEI-annotated texts (novels, dramas, poems, etc.). In total, it would be around 3 GB XML data in some 1000 files, the text size varies from 29 KB to 94 MB. I have a server running with Java 1.6.0_07 on CentOS 5.7 on a Virtual Machine with 1 GB RAM. I started to add files to the database and wrote a preliminary query interface (<http://oldphras.unibas.ch/cgi-bin/basex-client.pl>). Since we want to look for examples of multi-word units, I would like to use queries like: //(p|l) [text() contains text "Korb geben" using stemming using language "de"] (In the end, queries will be more complex to allow users to search for several words in different word order within a sentence using stemming or fuzzy) To make inspection of results easier, I added ft:mark. A collection with only a dozen of texts of about 71 MB with full text index for German, optimized, etc. works quite well. However, the example query needs more than 9s, which is rather slow. What is worse: Adding more files, resulting in about 323 MB, causes a timeout when running the query. I already set the memory for the Java VM to 1024, but it does not help. I tried it with the GUI on my iMac with 4 GB RAM and got a time out when the collection size is above 900 MB (which is still only a small part of my data). Is there any recommendation for size of RAM or specific settings when processing collections of about 3 GB? Is there a better way to write queries when looking for inflected forms of several words and allowing for spelling errors? Thank you in advance Cerstin -- Dr. phil.

workaround for lack of http_proxy support
by jidanni＠jidanni.org 17 Jan '12

17 Jan '12

Whilst waiting for Debian's basex to support http(s)_proxy, I found a workaround: installing the caching proxy WWWOFFLE, one then can use $ basex -q 'doc("http://localhost:8080/http/example.org/api?xyz")' without which I would very fast exceed daily API usage limits for mere repetitive tests.

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

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
