searching against base-uri
by David leigh 08 Feb '11

08 Feb '11

When I search against lyrics in my song database using "contains text", text is found where ever the input string is found, even if the string is simply part of a word. So "wor" would find "word". If I search with base-uri($song)[ . contains text "wor"] the results are interesting. Say I have the following files in my database: c:\song\music in the air c:\songs1\songbird review c:\songs2\songbird cafe c:\lyrics\songbirds singing c:\Songs3\I like to sing c:\Songs4\Songs worth singing searching with base-uri($song)[ . contains text "song"] will return: c:\song\music in the air c:\songs1\songbird review c:\songs2\songbird cafe c:\lyrics\songbirds singing c:\songs4\Songs worth singing searching with base-uri($song)[ . contains text "songs"] will return: c:\songs4\Songs worth singing My conclusion is that after the last slash (and in the database, of course, they are forward slashes) the string can be found as a substring but before the last slash, the string must be found as that whole section of the path (I've tried this with multi-word path sections and the entire path section must be specified or that node is not selected.) This is not particularly troubling, but I'd like to confirm that the behavior is expected. It would appear that the indexing is different for these file system path sections than for the actual file name at the end of the path (which appears to be indexed like all the other text). Can someone confirm this? Thanks!

Is there a way to not wrap results in jax-rx:results and jax-rx:result
by software developer 08 Feb '11

Hi, Since the queries to a collection over REST typically result in XML being returned, is there a way to turn off the wrapping of results in jax-rx:results and jax-rx;result elements? Thanks.

order nodes by dateTime
by Sony Vijay 07 Feb '11

07 Feb '11

Hi, I am using BaseX 6.5 database. Say I have the documents : doc1, doc2 in my database and the first child node of these documents is "updatedTime". Say the "updatedTime" node of doc1 and doc2 have the values : 2011-02-07T14:40:00.78-05:00 and 2011-02-07T14:41:02.133-05:00 respectively. I am trying to return a sorted list of document names in the descending order of the updatedTime node. I tried the following xquery: for $doc_name in db:list() order by xs:dateTime(doc($doc_name)/updatedTime) descending return $doc_name The output I receive is [doc1, doc2]. But, the expected output is [doc2, doc1]. I tried both ascending and descending in the order by statement but I get the same output. I am not sure how the ordering of elements by dateTime works. Could you help? Thanks, Sony PS: This is a simplified version of my code. The actual nodes have namespace prefixes. I hope the solution would be consistent when namespaces are used.

Retrieving the parent nodes of full-text search results
by Sony Vijay 07 Feb '11

07 Feb '11

Hi, Is there a way to retrieve the parent/ancestor nodes of the full-text search results of a basex database ? For instance, consider I have a document named 'feed1', 'feed2', 'feed3' in my database. A sample document ('feed1') looks as follows: <feed> <id>1</id> <updated>2011-02-07T07:10:49.588Z</updated> <title>feed1</title> <entry> <id>59</id> <title>Feed1 Root Package</title> <updated>2011-02-07T07:11:01.324Z</updated> </entry> </feed> The following xquery: for $doc_name in db:list() return (ft:extract(doc($doc_name)/feed/entry/*[text() contains text 'Root Package'])) outputs the following result as expected : <title>Feed1 Root Package</title> But, is there a way to retrieve the parent and ancestor nodes of the resulting <title> node, meaning is there a way I can output the 'id' of the entry and 'id' of the feed as well. The desired output could be: [<title>Feed1 Root Package</title>, <id>59</id>, <id>1</id>]. Thanks, Sony

Re: [basex-talk] Uncaught bounce notification

Hi don't know why, but your mails seem to be rejected by our mail server.. Anyway, regarding OWL is a large topic, so I doubt this will be completely covered in near future. Do you have some scenarios in mind that are already supported by other XML databases?

Hallo Michael, XML-Files werden direkt in BaseX gespeichert, wenn man sie in eine DB importiert. Die Funktion file:read() hingegen greift direkt auf eine Datei im Filesystem zu.

Search interface for Mailing Lists
by Christian Grün 05 Feb '11

05 Feb '11

Dear all, as has been discussed some days ago, the search for postings in our mailing lists is a tedious job: Mailman does not offer any search features, and the search engines seem to be too phlegmatic to browse the archives more frequently. To fix this, I've created the following page… http://basex.org/open-source/search/ …which allows you to search through all contents of our mailing lists. Full-text indexing, searching and result creation is all done by the BaseX engine, and the database and index is updated every hour. Feedback is welcome, Christian

Re: [basex-talk] Including the "doc" information in the RETURN clause
by David leigh 03 Feb '11

03 Feb '11

Ok, I got it figured out from this page: http://docs.basex.org/wiki/Database_%26_Collection. So, in my return concat, I need to use the "base-uri" of $song to get the actual file path. So, my query will look something like: for $song in collection("OpenSongSearch") where $song/song/lyrics[ . contains text "baloche"] or $song/song/title[ . contains text "baloche"] or $song/song/author[ . contains text "baloche"] order by $song/song/title return concat(base-uri($song),string('|'), $song/song/title,string('|'),$song/song/author,string('|'),replace(replace($ song/song/lyrics,'\n','^line^'),'\[\w+\]',''),string('
')) Yep, that works! Sorry to bug you all with a question that's documented! Are there other options than base-uri? For instance, base-uri has the file name. Is there a function like that with just the path but not the file name? If not, I can certainly work with base-uri. (I couldn't find any, but thought I'd ask) Thanks!

this mailing list's Google search index: last (only) update around Jan 26?
by Imsieke, Gerrit, le-tex 03 Feb '11

03 Feb '11

Michael, I was wondering why the most recent posts don't seem to be indexed. If you pick examples from the January list , you'll probably notice that the most recent posts are from Jan. 25: [1] indexed, [2] not indexed. Maybe this is because the bot (if it ever returned after initial indexing) looked at [3] and didn't notice any change, so it didn't descend further. If this is the case and the bot returns daily or so, we should see some change soon because February is new on [3]. But I doubt that the bot ever came back after Jan 26. You could try to submit a changed sitemap.xml each month, pointing to that month's message overview page and specifying a changefreq of 'daily' [4] for that page. Don't know whether Googlebot will take this into account though. But other ways such as the infamous revisit-after meta tag won't work at all, I was told. -Gerrit [1] https://mailman.uni-konstanz.de/pipermail/basex-talk/2011-January/001072.ht… [2] https://mailman.uni-konstanz.de/pipermail/basex-talk/2011-January/001073.ht… [3] https://mailman.uni-konstanz.de/pipermail/basex-talk/ [4] http://www.google.com/support/webmasters/bin/answer.py?answer=183668
