full-text search with wildcard
by Shakila Shayan 13 Mar '12

13 Mar '12

Hello all, We are using Basex 7.0.2 and using wildcard for full-text search we ran into some problems when it comes to tokenization related issues. Our database contains these entries: bb (aa)bb bb(cc) (aa)bb(cc) We ran a test as following with the given results shown in each case: 1- .//value[text() contains text {'.*(bb)'} using wildcards] returned (aa)bb and (aa)bb(cc) 2- .//value[text() contains text {'.(bb).*'} using wildcards] returned bb(cc) and (aa)bb(cc) 3- .//value[text() contains text {'(bb)'} using wildcards] returned (aa)bb and (aa)bb(cc) and bb(cc) and bb so far so good, but the following case is the weird case: 4- .//value[text() contains text {'.*(bb).*'} using wildcards] returning only (aa)bb(cc) Can anyone explain why is the behavior of the last case different? Whereas it should be the most general case , it turns out to be the most exclusive one ? Are we missing something or is it a bug?

BaseX 7.1.1 WAR problems: Permissions and other issues
by pw＠themail.co.uk 12 Mar '12

12 Mar '12

Hello I am having the same problems with the WAR version of 7.1.1 as described for 7.0 earlier { https://mailman.uni-konstanz.de/pipermail/basex-talk/2011-October/0020 28.html } There is duplication of the servlet.jar that prevents it from starting. Then after deletion of the servlet.jar, there are problems with permissions (I don't know the reason for this) I would appreciate help in getting the WAR version working both with Tomcat and with Oxygen. Can anyone provide details of how to remedy the situation with BaseX711.war and also an 'idiots guide' on how to sort out permissions, connect Oxygen to the database, and access via webDAV and rest interfaces.? Many thanks Peter

Performance and the capital of Albania
by Andy Bunce 09 Mar '12

09 Mar '12

Using the factbook.xml database and a recent 7.1.2 beta, I am hitting some performance problems. To debug I have been trying some expressions in the GUI window. The goal is given a country id, get the capital. The examples use Albania ="f0_136" let $id:="f0_136" let $cap:=//country[@id=$id]/@capital return //city[@id=$cap] ------result------------ <city id="f0_1461" country="f0_136" longitude="10.7" latitude="46.2"> <name>Tirane</name> <population year="87">192000</population> </city> *Time: 0.7ms * Very nice. Sadly my code is not doing it like this! ( the xpath is being generated from some data description xml I have created) If I try in the GUI some Xpath variations they produce wildly different execution times let $id:="f0_136" return //city[@id=(//country[@id=$id]/@capital)] *26144ms* let $id:="f0_136" return //city[@id=//country[@id=$id]/@capital] *25157ms* let $id:="f0_136" return (//city)[@id=(//country[@id=$id]/@capital)] *550ms* let $id:="f0_136" return (//city)[@id=((//country)[@id=$id]/@capital)] *6087ms* I was expecting all these to perform about the same. They all produce the same result. /Andy

Gets name of collection
by Anh Thuấn 09 Mar '12

09 Mar '12

Hi BaseX team, I 've met a problem of getting the name of the collection when retrievingXQuery. I am looking for a node satisfying a certain condition on multiple collections (each collection is a database of BaseX), when it returns a result, I want to know the name of that collection. For example, here is my query: for $node in (Collection("Database1"),Collection(Database2"))/a[@attribute = "name"] return $node // I want to get of the name of the collection of the returned node here. I don't know if BaseX supports a certain function to get the name of the collection from a node or something similar. Or does it has a way to know the node belongs to which collection?

Hint for documentation of command: legal database names
by Andreas Rulle 06 Mar '12

06 Mar '12

Dear BaseX team, in this mail you receive a small suggestion for the command documentation http://docs.basex.org/wiki/Commands#CREATE_DATABASE The comment from the source code, see the class org.basex.core.Command and its method validName, "allows only letters, digits, the underscore, and dash." could be added as information about legal characters for database names to the page http://docs.basex.org/wiki/Commands#CREATE_DATABASE . Okay it is a wiki and therefore could be editited directly, but I want to inform the team about this suggetion first. Perhaps the page could have a paragraph "legal identifiers". With best regards Andreas

db:list-details() @modified-date not valid xs:dateTime?
by Charles Duffy 05 Mar '12

05 Mar '12

Howdy -- I note that the modified-date attribute given in db:list-details() is not a valid xs:dateTime value (being "DD.MM.YYYY HH:MM:SS" rather than "YYYY- MM-DDTHH:MM:SS"). Would a patch correcting this be accepted, or is its current form considered part of the public API? Thanks!

CHOP=false in a POST request ?
by Maud Ingarao 05 Mar '12

05 Mar '12

Hello, I need BaseX not to chop whitespaces while creating DBs out of my XML texts. I found this post : https://mailman.uni-konstanz.de/pipermail/basex-talk/2010-April/000213.html and this documentation : http://docs.basex.org/wiki/Options#CHOP But could someone please show me how to write it as a REST POST request ? I looked at examples here http://docs.basex.org/wiki/REST#Command_Line but always get a "Nodes must belong to "http://www.basex.org/rest"" error... Thanks a lot !!
