Adventures with XQJ
by Gardner, Arthur 16 May '19

16 May '19

Hi folks. First a disclaimer: I'm omitting a lot of information, because there is hardly any limit to what I could include. Instead, I'll mention what seems most important, then dialog if anyone shows an interest. The objective: convert an existing private java library from ddxq to BaseX. I am using these libraries, all coming to me via BaseX (I think): [cid:image002.jpg@01D50A5D.04478550] My intention is to use the local option ... this library is already running in the server (or in Eclipse). import net.xqj.basex.local.BaseXXQDataSource; Here's my connection code (actually a constructor method): public XQTransformer (String xqueryName) throws Exception { String queryPath = String.format(filePath, xqueryName); URI queryUri = new URI(queryPath); FileReader xqueryReader = new FileReader(new File(queryUri)); xqds = new BaseXXQDataSource(); //xqds.setOptions("serialize=indent=yes"); //xqds.setBaseUri(queryPath); xqconnection = xqds.getConnection(); XQStaticContext context = xqconnection.getStaticContext(); context.setBindingMode(XQConstants.BINDING_MODE_IMMEDIATE); xqconnection.setStaticContext(context); xqpe = xqconnection.prepareExpression(xqueryReader); } setBaseUri is for references from the xQuery to helper files in the same directory. Later I compensate by overriding the current user directory. But I am throwing an Exception here: while (!rs.isClosed() && rs.next()) { java.lang.NullPointerException at org.basex.query.QueryContext.next(QueryContext.java:353) at org.basex.query.expr.gflwor.GFLWOR$1.next(GFLWOR.java:64) at org.basex.query.QueryContext.next(QueryContext.java:353) at org.basex.query.scope.MainModule$1.next(MainModule.java:101) at net.xqj.basex.bin.h.b(Unknown Source) at net.xqj.basex.bin.r.a(Unknown Source) at net.xqj.basex.bin.bL.next(Unknown Source) at net.xqj.basex.bin.bR.next(Unknown Source) at com.emc.metlife.util.xql.XqueryTransformation.xmlFormatted(XqueryTransformation.java:89) at com.emc.metlife.util.xql.XqueryTransformation.getTransformedData(XqueryTransformation.java:194) at com.emc.metlife.util.xql.XqueryPooledTester.test(XqueryPooledTester.java:58) at com.emc.metlife.util.xql.XqueryPooledTester.main(XqueryPooledTester.java:43) The particular xquery file is working for me in the BaseX GUI.

Hallo Joshua (cc to the list). If you want to process data that is bound to environment variables or system properties, you can use fn:environment-variable or proc:property [1]. In the prolog of your XQuery module, you can specify external variables. If you call BaseX on command line, values can be bound to these variables via the -b option: query.xq: declare variable $v external; $v * $v command-line call: basex -b v=123 query.xq 15129 XQuery itself is a very powerful language, and the built-in BaseX XQuery modules allow you to do many things that you are used from other programming languages (accessing files, sending HTTP requests, processing archives, JSON, HTML, etc) [3]. If you should require features that are not part of XQuery of the provided languages, you can also resort to Java code [4] or integrate additional modules [5]. Hope this helps, Christian [1] http://docs.basex.org/wiki/Process_Module#proc:property [2] http://docs.basex.org/wiki/Command-Line_Options#Standalone [3] http://docs.basex.org/wiki/Module_Library [4] http://docs.basex.org/wiki/Java_Bindings [5] http://docs.basex.org/wiki/Repository On Wed, May 15, 2019 at 6:30 PM Joshua Kordani <joshua.kordani(a)speedcastwireless.com> wrote: > > Christian, > > Thank you for your reply! I feel confident in my ability to construct the system in question, but I'm wondering how much of it will live in XQuery and how much will remain outside. As I've read through the documentation in more detail since my initial email, I do not see how the current offerings of XQuery modules will provide this functionality (I.e. user input either from environment variables or command line options fed to XQuery scripts) nor do I see this in the various tools command line options although I have not exhaustively searched. If I am wrong, I would appreciate a pointer to such, otherwise I suppose the answer will have to come from using the BaseX libraries or APIs.

New user questions

Greetings all. I am attempting to setup an environment for processing junit xml output files, to be handed off to the end user. In general, batches of junit files will be imported over time, and as they get imported I wish to add timestamp tags to certain elements. Right now the only way I see to programmatically do this is take details from the filename, derive a datetime, and apply it to the elements in question that are associated with a given file. I am trying to make this process easy on the user, such that they specify a new file or set of files to import, then all pertinent records in each file get timestamped. I don't quite see how to access enough "external environment" to allow for a script to grab a user specified filename and do this work and I could use some pointers. I undertand that datetimes are not indexable fields, or else i'm not sure exactly what the documentation has to say about indexes and datetimes, but if there is anything I can do to allow a user to filter by them that would be great. The user is fine with what ultimately becomes a command line interface to import these files and generates reports. I can see how to build xquery commands to isolate all of the elements in question and pass statically baked data to variables such as date time to add to existing elements in the database, but I still am not sure how to use this to build a system to allow a user to add a file or set of files at a time and have them processed in this way.

A really basic question
by Gardner, Arthur 13 May '19

13 May '19

Hi. I've installed the Windows Installer (9.2.1) in Windows 10. The installed shortcut points to BaseX.exe. When I click it, I see this message: This app can't run on your PC If I modify the shortcut to point to BaseX.jar, it runs like a champ. I haven't actually asked a question, but I guess you get the idea. The issue could be on my end, of course.

Did you already manage to send a successful request via curl or via any other ways?

Hi everyone, i am trying to send a post request to google token endpoint. However, I am not able to send a list of parameters in the POST request. Does anyone have an idea how to do so? Thank you in advance
