REST service problems - 401-Header sent‏
by MyNew EMail 02 Jul '12

02 Jul '12

Hi again, > What do you exactly mean with "long XQuery request"? Could you provide > us with an example that demonstrates the problem (I didn't manage to > track it down locally)?I'm using PHP with cURL to call the REST service (with standard username and password [admin, admin] for testing). Furthermore I'm using the BaseX HTTP Server (basexhttp.bat).Here is some code summary (first example works well): <?php//... $query = 'let $x := <abc> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> </abc> return insert node $x as last into //test'; $fullQuery = '<query xmlns="http://basex.org/rest">'; $fullQuery .= '<text><![CDATA[ '.$query.']]></text>'; $fullQuery .= '</query>';//...//set authorization stuff//set Content-Type header to application/xml and send a POST request to http://localhost:8984/rest/MyDb/test.xml with $fullQuery in body.//This works. Example XML will be inserted.?> But if the XML part (let $x := ...) or the XQuery part is longer I get this response (and I'm authorized the same way as in the first example): HTTP/1.1 401 Unauthorized WWW-Authenticate: BasicContent-Length: 31 Server: Jetty(6.1.26) This example does'nt work:<?php $query = 'let $x := <abc> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <aaa>Test</aaa> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> <bb test="123"><a>test</a></bb> </abc> return insert node $x as last into //test'; $fullQuery = '<query xmlns="http://basex.org/rest">'; $fullQuery .= '<text><![CDATA[ '.$query.']]></text>'; $fullQuery .= '</query>'; //...?> Removing whitespaces makes it possible to send a request which is a bit longer, but not very much. Is there a solution to send requests like this, maybe in a different way? It is important to make bigger updates on my XML data with REST. Greetings @all

Sending DELETE request through HTTP Module
by Seenivasan Gunabalan 02 Jul '12

02 Jul '12

hi, My objective is to delete the collections/files through the DELETE request using HTTP module. The DELETE operation does fine, when I ran it from BasexGUI. But if i put the same query inside delete.xq and invoke it by http://localhost:8984/rest?run=delete.xq, The request never returns any response and possibly got hanged. I need to restart the database to make the database to function. I am enclosing the xq i used, import module namespace http='http://expath.org/ns/http-client'; declare function local:cleanlist() { ('sample/record1','sample/record2','sample/record3') }; declare function local:cleandb() { try { for $cl in local:cleanlist() return http:send-request(<http:request method="DELETE" href="http://localhost:8984/rest/{$cl}" status-only = "true" username = "admin" password = "admin" send-authorization="true"> </http:request>) } catch err { err:description } }; <cleandb>{ local:cleandb() }</cleandb>

normalize-unicode function
by Toshio HIRAI 02 Jul '12

02 Jul '12

Hi, I tried some Japanese letters in fn:normalize-unicode. FULLWIDTH DIGIT, FULLWIDTH LATIN CAPITAL LETTER: fn:normalize-unicode("１２３４５６７８９０ａｂｃｄｅｆｇ", "NFKC") returns 1234567890abcdefg FULLWIDTH EXCLAMATION MARK: fn:normalize-unicode("！", "NFKC") returns ! FULLWIDTH LESS-THAN SIGN, ?FULLWIDTH GREATER-THAN SIGN: fn:normalize-unicode("＜＞", "NFKC") returns <> FULLWIDTH AMPERSAND; fn:normalize-unicode("＆", "NFKC") returns?& These are normal. but, FULLWIDTH QUOTATION MARK, FULLWIDTH APOSTROPHE: fn:normalize-unicode("”’", "NFKC") returns ”’ In this case, I think that "' should be returned. Best regards, Toshio HIRAI

REST service problems - 401-Header sent
by MyNew EMail 01 Jul '12

01 Jul '12

Hi, I am using the REST service of BaseX. I'm using POST with the following body to send requests (XPath/XQuery): <query xmlns="http://basex.org/rest"> <text><![CDATA[ (//city/name)[position() <= 5] ]]></text></query> (it's the example from the documentation) Most of the time it works well, but when the XQuery request is to long I get a 401 status code (not authenticated) while I am authenticated. Is there any solution for this problem? Thanks @all

Full-text search and mixed content
by Michael Piotrowski 27 Jun '12

27 Jun '12

Hi, In "XQuery and XPath Full Text 1.0 Use Cases" [1] it says: Querying across element boundaries is similar to an XQuery and XPath character string function converting the sub-tree under an element into a string by removing all markup. However, I'm having trouble to get this to work in BaseX 7.2.1. For example, given this document: <doc> Lorem ipsum dolor sit amet Lorem ipsum dolor sit amet Lorem ipsum dolor sit amet Lorem ipsum dolor sit amet </doc> How do I query, for example, for p elements that contain the string "sit amet"? //p[. contains text 'sit amet'] returns only paragraphs 1 and 2. I've tried a number of variations, but I've been unable to come up with a query that returns all four p elements. Are my queries incorrect or is this a bug in BaseX? Thanks and best regards Footnotes: [1] <http://www.w3.org/TR/xpath-full-text-10-use-cases/> -- Dr.-Ing.

how to formulate an excluding xquery?
by Cerstin Mahlow 27 Jun '12

27 Jun '12

Hi, in my project, users look for text nodes containing certain words. However, some of these queries result in a very large number of hits, with a lot of irrelevant ones. Is it possible to search with excluding xqueries? For example in this document A B C D E F A B D E F C A B D E F A B D F when looking for [text() contains contains text "A" ftand "B" ftand "E" ordered distance at most 3 words] I would like to make explicit, that "C" should not occur at all, to ensure to find only the third node, not the first nor second one -- i.e., "C" should not occur outside the sequence, nor inside the sequence. Is this possible at all? Can I also specify a query where "C" would be allowed to occur outside the sequence, like in the second node, but not inside like in the first node? Or the other way around?

log files
by Cerstin Mahlow 27 Jun '12

27 Jun '12

Hi, where are the log files stored? I recently copied the basex/data directory to another computer via scp and I saw that files like "2012-05-04.log" have been copied, too. But I do not find them in the original directory and also not in the target directory. Best regards Cerstin -- Dr. phil.

full text search collation
by alxarch 26 Jun '12

26 Jun '12

Hi I have a question relating to full text search. I am trying to use it with Greek texts and the default collation assumes that ά != α In short, accented vowels are treated as different letters. Is this something that has to do with the collation used not being Greek, or does it have something to do with the tokenizer? As a side question i noticed that the stemmers used from lucne are quite outdated. 3.6.0 also includes a Greek stemmer. I tried to include the 3.6.0 stemmers instead but language codes seem to be hardcoded in util/ft/Language.java Any chnce of that part of the code being updated to use the latest stemmers so more languages can be integrated? (i am not proficient in java myself unfortunately so i can't directly help) thanks, Alex

Validation Module
by Seenivasan Gunabalan 25 Jun '12

25 Jun '12

Hi all, I am trying to validate an incoming xml post message against an xsd stored inside the basex. But I am getting this error [FODC0002] Resource 'sampledb/xsd/match.xsd' does not exist. I am sure the path is correct and the xsd file exists there. May I know where I am going wrong? try { let $doc := |<simple:||root| |xmlns:simple=||'http://basex.org/simple'||/>| return validate:xsd($doc,'sampledb/xsd/match.xsd') } catch BXVA0001 { 'Validation failed.' } Thanks in advance.

BaseXClient
by Willian Barcella 24 Jun '12

24 Jun '12

Hi All, I builded a kind of connection pool using BaseXClient.java class, I simulated several users trying insert documents in BaseX, the result was a disaster. ERROR: data.BaseXDataAccess - Error closing db java.io.IOException: Stopped at line 1, column 19: Unknown command: 1340477810253095000. Try HELP. at data.BaseXClient.execute(BaseXClient.java:99) at data.BaseXClient.execute(BaseXClient.java:110) at data.BaseXDataAccess.save(BaseXDataAccess.java:169) at data.TestInsert$Insert.run(TestInsert.java:88) at java.lang.Thread.run(Thread.java:680) Exception in thread "Thread-1" java.lang.RuntimeException: java.io.IOException: at data.BaseXDataAccess.save(BaseXDataAccess.java:164) at data.TestInsert$Insert.run(TestInsert.java:88)ERROR: com.xftec.hyperion.data.BaseXDataAccess - Error closing db I started several threads each one takes a BaseXClient connection and as soon as it finishs its job BaseXClient is put in a queue again to be took by other thread.
