File module path encodings
by Andy Bunce 12 Apr '13

Hi, The following two expressions create a file called "d d.txt" (Windows, BaseX 7.6) file:write("c:\temp\d d.txt","what") file:write("c:\temp\d%20d.txt","what") I wonder if it would not be better if the second would create a file "d%20d.txt"? My use case is creating a file name that encodes a path e.g. "lib%5Cfile.txt". The currently gives an error, as it is looking for a folder lib. I read http://expath.org/spec/file#d3e112 as meaning url encoded file names must start file:/// and if no file:/// the name should be used as is. /Andy

Dear Team, Following is my query - for $x in db:fulltext('Doc', 'Molecular Biology')/ancestor::*:Doc return $x/ArticleNo This query will return all the ArticleNo having the words "Molecular Biology" The output of this query is like a PHRASE... where the phrase is "Molecular Biology" Now I want to list all the ArticleNo which might have word "Molecular" OR/AND "Biology" How can I get this using the above query... ?? -- Have a nice day JBest

Java Exception:insertion at beginning of populated table
by Nicholas OR Rita Stevens 12 Apr '13

12 Apr '13

Via a python client, I am looping through a set of 600 xml files and issuing REPLACE commands to store them in my BaseX db. All was well until I reached file #364, at which point the program crashed with Java.lang.RuntimeException: "insertion at beginning of populated table." I am using BaseX 7.7 beta. I guess I shouldn't be using beta?

Letting users WRITE comments, but not READ them.
by France Baril 10 Apr '13

10 Apr '13

Hi, I am trying to secure access to some of our content. Case: 1. User reads our content and completes the feedback form. 2. A file is saved in our "Feedback" database for each form that is submitted. Security: - Let anonymous users WRITE to the DB using the web form - Do not allow unauthenticated users to READ comments. Solution so far to avoid making user/password known: 1. Save feedback in an unsecured DB. 2. Redirect to function that moves the feedback file to a secured DB. Issue: - Security seems to limit access to files when they are addressed as db:open(DB, path). - All functions that grab data, crunch the data and display it in an HTML table seem to remain available to everyone. Questions: - Instead of securing the DB, we were thinking of securing the functions: Open access to 'submit-comment' for all users, require authentication for all other functions. Is this possible, if so can you point me to useful documentation? - Do you have any other suggestion? -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

quick dereferencing of elements found earlier
by C. M. Sperberg-McQueen 06 Apr '13

06 Apr '13

I'm experimenting with the construction of secondary documents which contain information about my primary documents. I won't go into details, but it would not be too far off to think of them as user-created indices -- my goal is to pre-calculate some information I expect to want often in queries, to see if using such secondary documents produces faster responses than running the original queries on the original documents. It would be handy to be able to point from my secondary documents to specific nodes (in my case, always elements, at least at the moment) of the primary documents. The same desire arises when I try to build text search interfaces that return hits with a small amount of context; I want to be able to provide links that point to an appropriate ancestor element, so the user can see more context if desired. One way to handle this desire would be to take the base URI of the node, and the path from the root to the element and point to elements using XPointer element() expressions of the form collection/docname.xml#element(1/2/4/1/1) (A function for fast resolution of XPointer element() expressions would be a nice thing to have, by the way.) In some XQuery implementations, I believe there are functions which return some sort of internal identifier for element nodes, and other functions which take that identifier as an argument and quickly return that node. (Or perhaps I am just remembering a facility from the first SGML database I used intensively.) Such functions, if they exist, seem likely to be faster than resolution of element() expressions. Is there anything like that in BaseX? Thanks! -- **************************************************************** * C. M.

How to get list as result instead of a String
by elangovan MuthuSwamy 05 Apr '13

Hi All, I am using XQuery to evaluate an xpath. My code is as follows, /*Example xml I am using <interface> <name>intf0</name> </interface> <interface> <name>intf1</name> </interface> <interface> <name>intf2</name> </interface> <interface> <name>intf3</name> </interface> */ XQuery query = new XQuery("/interfaces/interface/name/text()"); String str = query.execute(ctx); // Result string is - intf0intf1intf2intf3 I want the result such as intf0 intf1 intf2 intf3 I could not get the result list and I could not differentiate whether the result has multiple values or a single value. Please advice me if there is any other way to identify the result list. Thanks in Advance. -- Regards, Elango.

for consideration/request

Van: Rob Stapper [mailto:r.stapper@lijbrandt.nl] Verzonden: donderdag 4 april 2013 13:13 Aan: Christian Grün Onderwerp: tip/request Hi Christian, Im working with Basex 7.7beta now without any problems. The trace-function also works much better except .. it doesnt work with mappings. I make intensive use of recursion and mappings and for debugging it would be nice if the trace-function would also work with mappings. I wouldnt ask you to implement this if it wasnt so easy to program in Xquery, see attachment. I use this programmed version but I think it would be nice if the trace-function could also process mappings. Just something to consider ? Greetings Rob Stapper

Usage of HttPS and encryption
by CAUVE alexis 04 Apr '13

04 Apr '13

Hello, I yet use BaseX successfully, With the help of the Java BaseXClient exemple. I work on some sensible data and so I wonder if it is possible to use HTTPS to connect to the DB with the REST protocol. An other question is: would it be possible to work with XML files encrypted to avoid them to be readable and to baseX able decrypt the files content while we do queries on it ? Maybe it would result a big lost of performances BaseX is a usefull work. Thanks for it.
