document-uri() and directory structure within collections
by C. M. Sperberg-McQueen 22 Jun '10

22 Jun '10

I've used BaseX to create a database of the XML Schema Test Suite, by specifying (in the GUI) the test suite's root directory and a filter of *.xml. (Well, to be completely explicit it's the root directory of a mirror in which each file is a symbolic link to the real test suite directories; this allows me to exclude ill-formed input and rename all XSD files as .xsd.xml.) But I find that when I retrieve an element $e and ask what document it was in, using document-uri($e), I do not get the expected result: I get the file name of the document, but I do not get the path to the document, only the path to the database root. For example: the BaseX database I'm working with was created by indexing directory /home/xmlschema/mirror-11. And for a query result element $a found in document /home/xmlschema/mirror-11/msData/additional/test73850.xml the expression document-uri($a/root()) returns /home/xmlschema/mirror-11/test73850.xsd.xml instead of the expected /home/xmlschema/mirror-11/msData/additional/test73850.xml (Side note: I do realize that the 'root()' in '$a/root()' is irrelevant; it's there to work around a bug in another XQuery processor, which shall remain nameless, which otherwise returns the empty sequence. Yes, it's true: I am seeing other XQuery engines as well as BaseX. I blush to admit it, because it makes me seem kind of promiscuous, but it's true.) Is this a bug? Did I do something wrong / set some parameter wrong when creating the database?) Is there a workaround? If it matters, I'm running BaseX 5.7 (cannot move to BaseX 6 at the moment because no Java 6 is available for my current hardware and software). -- **************************************************************** * C.

create / aler problem
by szabolcs kurdi 19 Jun '10

19 Jun '10

Hi! I seem to have some problems with creating or renaming databases with dots in their names. From java using create (I'm using CreateColl) they are created fine, but from the gui the last set is truncated (something.dot1.dot2 -> something.dot1). Rename (AlterDB from 6.1.7) can't rename a db with dots in its name, but no BaseXException is raised. Is it a bug, or just using dots in the names (which are directory names of course) is not advised? Thanks! Szabolcs

XQuery FLOWR and Context
by Dave Glick 18 Jun '10

18 Jun '10

Hello again, You guys do such a great job of answering and responding to questions and concerns on this board, thanks again for that Christian. This next one might be a case of misunderstanding the standard on my part, but I'm seeing some odd things with XQuery when using a different initial context than the document root. Take the following XML: <test> <a> <aa/> <ab> <aba/> <abb/> <abc/> </ab> <ac/> </a> <ba/> <bb> <bba/> <bbb/> <bbc/> </bb> <bc/> </test> Here is the result of several different XQuery commands with different initial contexts (I've loaded the document into the BaseX GUI and am setting initial context by double-clicking the element in the grid view)... Query: . Context: document, Result: The entire document (as expected) Context: , Result: The element and all its content (as expected) Query: let $v := . return $v Context: document, Result: The entire document (as expected) Context , Result: The entire document (was expecting the element and all its content!) Query: .//ab Context: document, Result: Result: The <ab> element and its content (as expected) Context , Result: Nothing (as expected) Query: let $v := //ab return $v Context: document, Result: The <ab> element and its content (as expected) Context: , Result: The <ab> element and its content (as expected) Query: let $v := .//ab return $v Context: document, Result: The <ab> element and its content (as expected) Context: , Result: The <ab> element and its content (was expecting nothing!) As you can see, it seems to behave counter to expectations when the initial context is not the document and I use the initial context in the FLOWR expression. I attempted to test in other tools, but it appears that setting the initial context for an XQuery expression is actually a difficult feature to find. It's not a totally academic question, though - the system we're building uses initial contexts pretty extensively. I know that context is not maintained in XQuery, but can the initial context not be used in variable assignment or other components of a FLOWR expression? Thanks, Dave

tablemem
by NewIntellectual 18 Jun '10

18 Jun '10

I've tried to figure out how to use the described 'tablemem' command ("Loading database table into main memory and speedup evaluation times"), unsuccessfully so far. Can this be invoked both in the BaseX GUI and in a client call to the server? Surely it would only make sense to make the call once after server startup.

default basex data directory
by szabolcs kurdi 18 Jun '10

18 Jun '10

Hi! I know that one can move the BaseXData directory from his or her home, but wouldn't this directory be better placed into something like "Application Data" (Windows), or ".BaseXData" on linux and friends by default? Is there a reason that the data directory is so "visible"? Maybe I have missed something here and that's how it should be - thanks! Szabolcs Kurdi

Leave whitespaces in XML when loading XML file with new CreateDB
by Jiří Kadlec 17 Jun '10

17 Jun '10

Hi Guys, How can I preserve whitespaces in XML document, when i'm using new CreateDB(..) object for creating new database from Java code. When I export data with new Export(..) I get document with choped whitespaces. I found out, that there is a possibility to preserve whitespaces when I create DB from BaseX gui. There is a possibility to uncheck option chop whitespaces which gives me required result. Is there any way how to do this from Java. Thank you Jiri

heterogeneous collections, filter notation, and/or add command
by C. M. Sperberg-McQueen 15 Jun '10

15 Jun '10

I'm trying to build a BaseX database containing the current contents of the XSD 1.1 test suite, and have run across a problem I suspect is easily soluble, but for which I am not finding the solution. The directory tree containing the database includes a large number of test cases, mostly files with names ending in .xml, and a smaller number of schema documents for the test cases, which mostly have names ending in .xsd. (One set of test contributions has three or four .xml files which are not in fact XML but which are testing the behavior of the processor in the presence of ill-formed input. I've renamed these so their names end in .xmlnwf, because they were causing attempts to index all the XML documents to fail.) There are also XML files with metadata for the test cases, some of which have names ending in .xml and some with names ending in .testSet. And there is some random stuff that I'm not particularly interested in indexing: some README files, a Microsoft Word document included by one organization contributing test cases, and (since I'm working under Mac OS X) some .DS_Store files containg OS-level binary metadata about the directory. There may be other files in the directories as well; I haven't tried to make a full census. If I could, I'd tell the database creation dialog to index everything it can parse as XML and ignore the rest. But when the parser encounters ill-formed input, it issues an error message and aborts the creation of the database. (And then the message disappears, so the user doesn't know which file caused the problem. If you could change that, it would be great, but really that's a separate issue.) Alternatively, I'd like to tell the creation dialog to use a filter that accepts either .xml files or .xsd files or .testSet files. But I can't figure out what notation to use for that. Since the example given ("*.xml") looks like a bash wildcard, I've tried "*.xml, *.xsd, *.testSet", and "*.xml,*.xsd,*.testSet" and "*.xml *.xsd *.testSet" and "*.{xml,xsd,testSet}", none of which match any files. Is there a way to specify a filter that matches several file extensions? Guided by http://www.inf.uni-konstanz.de/dbis/basex/commands I then tried add /home/xmlschema/xsts11/*/*.xsd in the command area in the GUI, but it tells me the command ADD is not known. (Perhaps this is because I'm still using 5.7; perhaps ADD came later?) I'm hoping wildcards are allowed in ADD commands, because the task of finding and adding fourteen thousand .xsd files would be a bit tedious. (I suppose I could use the command-line interface to do it.) It would also be nice to have the ADD functionality better integrated into the GUI. (How spoilt I have become! I can't believe I'm not using the command line, but the syntax checking in the query window is too helpful for me.) Any advice on (1) the notation of the filter parameter, (2) the use of wildcards in the ADD command, or (3) any other way to solve this task and build this database? I'm using the GUI interface to BaseX (odd; my name for the app makes clear I think it is version 5.7, but the About dialog box gives the number 12.2). I'll send this note, and then download and install 6.1 to see if it helps. -- **************************************************************** * C. M.
