Full text score with or
by Andy Bunce 23 Nov '14

23 Nov '14

Hi, I want to score searches with multiple conditions e.g. let $data:=( <r><a>red apple</a></r>, <r><a>blue lagoon</a></r>, <r><b>fish and chips</b></r>) for $hit score $s in $data[ a contains text("red") or b contains text("fish")] return $s In 7.8.2 it always returns scores of zero. In version 7.6 it returns numbers like 0.6201145069582775 0.4528324252639413 Is this bug? Regards /Andy

stream binary responses from http:module
by Johan Mörén 10 Nov '14

10 Nov '14

Hi I have built a small client in XQuery that fetches zip files from another remote service using the http-module and stores them on disk with the help of the file-module. Some of the returned zip files are really large and BaseX seems to need to materialize the files in memory before writing them to disk resulting in out of memory errors for some files. Is there some way read the response in a more streamable fashion when using the http-module? I tried using the fetch:binary function successfully but i really need the more extended functionality of the http-module. #results in out of memory if the zip file is too large file:write-binary("file.zip", http:sendrequest(...)[2]) #works all the time. file:write-binary("file.zip", fetch:binary(...)) Regards, Johan

JSON or JSONML output formatting
by Zachary Pride 16 Jul '14

16 Jul '14

Hello, I've been playing with BaseX lately and all-in-all am very impressed. Something I'm wrestling with however is the JSON output options. I've got various web applications that would really be simplified by receiving JSON straight away for the obvious scripting benefits. The JSON method has been giving me a lot of grief, stipulating rules I'm not sure how to follow. right now I have an element that "is typed as string and cannot be nested." I've been able to get JSONML to output but the JSON is this morass of nested Arrays... Attributes seem to get transformed into Objects but elements/tags and their values are pushed into Arrays for some rationale - which I suppose is on purpose. My question is how can I get Objects for simple key:value properties from <tag>value</tag> 's. Are there options I'm not utilizing? Would it be feasible to transform the XML output to some middle form first - setting it up to become Objects, before serializing it to JSON? Thanks!

Re: [basex-talk] How to run several commands in one post
by Christian Grün 18 Jun '14

18 Jun '14

Hi Arjan (cc to the list), >> But then it is also not possible to start-up some existing server side script that way? I've added another idea to the reopened GitHub issue [1]: we could extend the "run" operation [2] to also support command scripts.

Hi Erol (cc to the list), > That solved the issue! > Thanks for your help > > I like to know what is difference between xs:int and xs:integer ? Values of type xs:integer may be bigger than Java integers. You'll need BigInteger to accept these values in a Java function. Hope this helps, Christian

USPTO XML format causes BaseX GUI errors
by Jose Rey 29 May '14

29 May '14

Hi, I am new to BaseX and will attempt to use it to analyze xml datasets from R at some point in the near future. I am using a BaseX GUI under Windows-7 operating system and had an error while trying to create a database using the GUI by using an XML file as input. The file comes from the US Patents and Trademarks Office (USPTO), and the larger XML datasets they provide have the same problem. The error text is: Command: CREATE DB ipgb20110104Sample C:/Users/admin/Downloads/ipgb20110104Sample.xmlError:"C:/Users/admin/Downloads/ipgb20110104Sample.xml" (Line 306): The processing instruction target matching "[xX][mM][lL]" is not allowed. The XML document I am trying to open is contained in this zip file: http://www.uspto.gov/products/ipgb110104-sample.zip The link to the document is in this page: http://www.uspto.gov/products/xml-resources.jsp under the "Patent Grant Data / XML ST. 36 (ICE) v4.2 (a.k.a. Red Book) (2007 - 2012)" section of the page, under the "Sample Documents (Bibliographic)" bulletpoint >From searching online, I found that the error is because of poor formatting in the file. However, larger datasets of the same kind (USPTO bulk download @ Google) have the same problem. In the specific case of the file I mention, it has a carriage return in the first line, and then has several concatenated XML files, which is the case of the larger XML files from the USPTO. My question is: Is there a work around to this error/problem? Can I somehow tell BaseX to ignore or somehow acknowledge that mistake and load the file(s). Thank you so much, Jose -- Jose I.

How to change processor to Saxon
by emchateau＠laposte.net 28 May '14

28 May '14

Using based to publish TEI-XML files, allows to take benefits from the Java's environment using XSLT 2.0. But we didn't cope with putting Saxon in the Classpath for BaseX. Is there any simple steps doing it ? On a mac, we were able to do it by putting the Saxon's jar files into `/Library/Java/Extensions/` Running basexhttp, the expression `xslt:processor()` returns "Saxon" and `xslt:version()` returns "2.0". On an ubuntu machine, there is no such directory for Java. We've first tried to set the CLASSPATH with `export CLASSPATH=/usr/share/java/saxon9he.jar` (and various other things) unhopely without success. Your help would be very welcome !

I am using basexgui.bat to open basex gui that will load all jars in libs folder. Is there anything I could not see here?
