reporting a BUG in the IOFile class
by VORS, Guilhem (CIMPA SAS) 09 Dec '11

09 Dec '11

To all the baseX team, First of all I would like to thank you for the great tool you made. We use it almost every day in our team. One member had actually developed a pluggin for xml validation some years ago. To the bug trackers, I would like to report a strange behaviour regarding the IOFile class, using baseX702 jar file, eclipse indigo, along with JDK 1.7.0_01 When trying to execute the CreateDB command to build a local baseX database from a distant file (say fileInputPath = "//filer/distant/file.xml"), when you proceed with the static method by doing: BufferedInputStream bis = new BufferedInputStream(new FileInputStream( fileInputPath)); SAXSource saxSource = new SAXSource(new InputSource(bis)); SAXWrapper saxWrapper = new SAXWrapper(saxSource, context.prop); CreateDB.create(dbName, saxWrapper, context); Everything works fine. BUT, when you try to do the same using the non static method, by doing (which I need because I have to report the progress of the create command in a JProgressBar): create = new CreateDB(dbName, fileInputPath); create.execute(context); You get the following exception: org.basex.core.BaseXException: "filer/distant/file.xml ": (here the path where the command is run)/filer/distant/file.xml (unknown path or something like that (in French it's :"le chemin d'accès spécifié est introuvable")). After some bug tracking, it appears that in the function create, in static class PathList, inside the IOFile class, there is a mistreatment of the path, here is the function: static class PathList extends StringList { /** * Creates a path. * @param path input path * @return path */ String create(final String path) { final TokenBuilder tb = new TokenBuilder(); final int l = path.length(); for(int i = 0; i < l; ++i) { final char ch = path.charAt(i); if(ch == '\\' || ch == '/') add(tb); else tb.add(ch); } add(tb); for(int s = 0; s < size; ++s) { // if(s == 0 && (path.startsWith("\\\\") || path.startsWith("//"))) tb.add("//"); // this is my current "hack" to resolve the problem) if(s != 0 || path.startsWith("/")) tb.add('/'); tb.add(list[s]); } return tb.toString(); } If I don't uncomment my line, I get the error described above, because the TokenBuilder remove the first two '/' from the path it builds. What I have done to solve the problem, is to make a local copy of IOFile + CreateDB, and I have added the line commented, to add the leading '//' in front of remote file access. This workaround works well for my project, but it is not convenient for me, as I would like to get the new versions of baseX. Could you please find a way to resolve this problem, I don't know if it is intentional, or even if I'm using it the right way. Again thank you for your professional quality software. I'm waiting forward to have news from you.

can't call the outer most return value by name
by jidanni＠jidanni.org 09 Dec '11

Odd, one can see <R> but not access by it. Run this: declare function local:K($x){ switch ($x) case 2 return <R><name>N</name><o><name>Y</name></o></R> default return() }; " A",local:K(2)//*:R, " B",local:K(2)/o/name, (: shows we are already at the root :) " C",local:K(2)/., (: reveals R is really in there, but can't be called by name :) " D",local:K(2)/./R What's the deal?

FW: database compatibility - adding several binary resource files
by Fabrice Etanchaud 09 Dec '11

09 Dec '11

Dear all at BaseX, 1. just in case... are databases created with BaseX 6.5 (and so backups) compatible with BaseX 7.0 ? 2. Is there a way to load several binary resource files with only one command or xquery function (like ADD or db:add for textual resources) ? Thank you for your fanstatic job. regards, Fabrice ETANCHAUD Senior Software Engineer edital Berkenlaan 1 B-1831 Brussels, Belgium <skype:fabrice.etanchaud?call> +32 2 716 32 32 general +32 2 716 32 20 fax fetanchaud(a)edital.com corsearch.com <http://www.corsearch.com/> | edital.com <http://www.edital.com/> Confidentiality Notice: This email and its attachments (if any) contain confidential information of the sender.

No results for query. Please help!
by Subhro Moitra 09 Dec '11

09 Dec '11

Hello, I am getting to know Basex702. I downloaded the war and its receiving requests at http://localhost:8080/BaseX702/rest (tomcat servlet container) I am using curl to query the REST urls for results. I used the command below to populate the initial data *$$ curl -i -X PUT -H "Content-Type: application/xml" -T "/tmp/bv_letsbuycom_standard_client_feed.xml" "admin:admin@localhost :8080/BaseX702/rest/bvstandard"* To confirm the PUT above i do this: *$$ curl -i "admin:admin@localhost:8080/BaseX702/rest/bvstandard"* .... ...... <rest:database name="bvstandard" resources="1" xmlns:rest=" http://www.basex.org/rest"> <rest:resource type="xml" content-type="application/xml" size="828733">bvstandard.xml</rest:resource> </rest:database> Another confirmation *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard/bvstandard.xml"* * * The above shows the entire xml. So the data got loaded fine i believe. Now i am stuck. a query like below is not resulting any results. The xml document surely contains the path and data. *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard?query=/Feed/Product&wrap=no"* There are multiple Product elements under the Feed element. And the above query returns empty results. I know i am doing something fundamentally wrong, but not sure what. However, a request like *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard?query=//@id"* * * Shows results as expected, ie all the attributes *id * and its values are displayed. Please help. Aren't the values of query param in the GET url above, a XPATH expression? How to i execute a xpath on the DB to get the results, using the REST interface. The main purpose is to get some 100 MB large xml file into BaseX and then query it using a php client and display results on a web page. We at letsbuy.com is really interested in integrating BaseX in our application for handling all the XML feeds we consume. Please advice. Thanks, Subhro.

Dear all, I'm trying to download a jpg from the web and then write it in a file. Everything goes right, but at the end the file is not a valid image... it contains extra bytes... could you please tell me where I went wrong ? declare default element namespace "http://www.w3.org/1999/xhtml"; file:write-binary('c:/fe/img.jpg', http:send-request(<http:request method='get' override-media-type=image/jpeg'/>, http:send-request(<http:request method='get' />, 'http://www.patentsoffice.ie/eregister/register/TMRegister.aspx?idAppli= 2005/01446')[2]//img/@src[contains(.,'TM')]/data() ) ) With a typeswitch I can see that the response body is a xs:base64Binary, so it should fit correctly in the file:write-binary function... best regards Fabrice ETANCHAUD Senior Software Engineer edital Berkenlaan 1 B-1831 Brussels, Belgium <skype:fabrice.etanchaud?call> +32 2 716 32 32 general +32 2 716 32 20 fax fetanchaud(a)edital.com corsearch.com <http://www.corsearch.com/> | edital.com <http://www.edital.com/> Confidentiality Notice: This email and its attachments (if any) contain confidential information of the sender.

BaseX on Android
by Andy Bunce 08 Dec '11

08 Dec '11

Hi, I remember seeing some discussion of research into this a while back. I have just got a Android tablet so was wondering what the state of play is on this? I come across JBED http://forum.xda-developers.com/showthread.php?t=1189303which seems to claim the ability to run jars though an emulation layer. I tried this but it is looking for a midlet/jad descriptor file. I will investigate this, but has anybody been down this route? /Andy

You see I'm trying to figure how to get a inner shred of XML, <description><![CDATA[<ul><li>復興廣播電台...</li><li>台北市士...</li><li>丙</li></ul>]]></description> parsed just like the enclosing file. Maybe I need some "util:eval()". You see I want to access the inner elements with //li[2] etc. instead of matches(*:desc,concat('/li><li>(',$x,')')) like a dweeb. Help.
