Readers of this list may be interested in the Balisage conference, which focuses on applications of markup. This year's program includes several talks on projects which use XQuery (often in the form of BaseX). I hope to see other XQuery enthusiasts at Balisage this year! Balisage: The Markup Conference 2016 Program Now Available http://www.balisage.net/2016/Program.html Balisage: where serious markup practitioners and theoreticians meet every August. The 2016 program includes papers discussing reducing ambiguity in linked-open-data annotations, the visualization of XSLT execution patterns, automatic recognition of grant- and funding-related information in scientific papers, construction of an interactive interface to assist cybersecurity analysts, rules for graceful extension and customization of standard vocabularies, case studies of agile schema development, a report on XML encoding of subtitles for video, an extension of XPath to file systems, handling soft hyphens in historical texts, an automated validity checker for formatted pages, one no-angle-brackets editing interface for scholars of German family names and another for scholars of Roman legal history, and a survey of non-XML markup such as Markdown. XML In, Web Out: A one-day Symposium on the sub rosa XML that powers an increasing number of websites will be held on Monday, August 1. http://balisage.net/XML-In-Web-Out/ If you are interested in open information, reusable documents, and vendor and application independence, then you need descriptive markup, and Balisage is the conference you should attend. Balisage brings together document architects, librarians, archivists, computer scientists, XML practitioners, XSLT and XQuery programmers, implementers of XSLT and XQuery engines and other markup-related software, Topic-Map enthusiasts, semantic-Web evangelists, standards developers, academics, industrial researchers, government and NGO staff, industrial developers, practitioners, consultants, and the world's greatest concentration of markup theorists. Some participants are busy designing replacements for XML while other still use SGML (and know why they do). Discussion is open, candid, and unashamedly technical.

Re: [basex-talk] Bug report in handling fn:format-number in basex 8.4.4
by Michael Stoop 03 Jun '16

03 Jun '16

Good morning, First of all thank you for your great work on basex. I've been phasing out Zorba in favour of BaseX for excellent large file support and all around better documentation and support. However, I'm running into some issues in formatting numbers in basex 8.4.4 using fn:format-number (using http://www.w3schools.com/xsl/func_formatnumber.asp) To describe this behavior I wrote a simple xquery: let $result := <rows> <row input="0.3576" format="0.##" expected="0.36">{fn:format-number(0.3576, "0.##")}</row> <row input="-0.3576" format="0.##" expected="-0.36">{fn:format-number(-0.3576, "0.##")}</row> <row input="-0.3576" format="0.###" expected="-0.358">{fn:format-number(-0.3576, "0.###")}</row> <row input="-0.3576" format="0.####" expected="-0.3576">{fn:format-number(-0.3576, "0.####")}</row> <row input="-0.3576" format="0.00" expected="-0.36">{fn:format-number(-0.3576, "0.00")}</row> <row input="0.000" format="0.##" expected="0.00">{fn:format-number(0.000, "0.##")}</row> <row input="0" format="0.00" expected="0.00">{fn:format-number(0, "0.00")}</row> <row input="0.3" format="0.####" expected="0.3">{fn:format-number(0.3, "0.####")}</row> <row input="0.3" format="0.0000" expected="0.3000">{fn:format-number(0.3, "0.0000")}</row> <row input="17" format="0.##" expected="17">{fn:format-number(17, "0.##")}</row> <row input="17" format="0.00" expected="17.00">{fn:format-number(17, "0.00")}</row> <row input="17.4555" format="0.##" expected="17.46">{fn:format-number(17.4555, "0.##")}</row> <row input="-17.4555" format="0.##" expected="-17.46">{fn:format-number(-17.4555, "0.##")}</row> </rows> return $result The result of this is as follows: <rows> <row input="0.3576" format="0.##" expected="0.36">.36</row> <row input="-0.3576" format="0.##" expected="-0.36">-.36</row> <row input="-0.3576" format="0.###" expected="-0.358">-.358</row> <row input="-0.3576" format="0.####" expected="-0.3576">-.3576</row> <row input="-0.3576" format="0.00" expected="-0.36">-.36</row> <row input="0.000" format="0.##" expected="0.00">0</row> <row input="0" format="0.00" expected="0.00">0.00</row> <row input="0.3" format="0.####" expected="0.3">.3</row> <row input="0.3" format="0.0000" expected="0.3000">.3000</row> <row input="17" format="0.##" expected="17">17</row> <row input="17" format="0.00" expected="17.00">17.00</row> <row input="17.4555" format="0.##" expected="17.46">17.46</row> <row input="-17.4555" format="0.##" expected="-17.46">-17.46</row> </rows> Unfortunately two things seem to go wrong here: · Zero in the picture string is ignored for negative numbers. · The zero before decimal is ignored for amounts between zero and one (but does occur for 0.0000 for example). I hope someone can take a look at this and provide a fix. I tried messing around with string replace functions where I would just replace -. with -0. and prefix the result for a decimal point with a zero, but this really isn't present and requires a workaround for something that is very common in my code. Using the latest basex (8.4.4) on Windows Server 2012 under Java 8 (64 bit, last update just now: update 91). Thanks in advance and best regards, Michaël Stoop

Replacing documents in remote database
by Asxetos 02 Jun '16

02 Jun '16

Hey all, I am trying to connect to a remote database and replace its files. I am using db:replace() inside client:query(), but I don't get how I am supposed to pass $input as the new data for the file in the database. Here a quick code snippet I put together: http://sprunge.us/jdaZ ( or http://sprunge.us/OZHj?xquery ) If there's a better method for doing what I am trying, I'm fine with replacing my whole method, even if that is using some sort of REST API and http requests. Just give me some pointers ;) Thanks!

Static files not accessed ?
by Maud Ingarao 31 May '16

31 May '16

Hello dear friends Since we upgraded to 8.3 or 8.4, we have strange behaviours with static files. For example, this file cannot be accessed when called from another xsl (include or import) as shown in the logs : [GET] http://rey.huma-num.fr/inventaire/Rey17470124; Stopped at /sites/papiersmmrey/resource/basex/basex.8.4.3/webapp/synopsx/mappings/htmlWrapping.xqm, 168/33: [bxerr:BXSL0001] Error on line 7 column 78 of tei2html-fiche.xsl: XTSE0165: I/O error reported by XML parser processing http://rey.huma-num.fr/synopsx/files/xsl/tei2html.xsl: Server returned HTTP response code: 502 for URL: http://rey.huma-num.fr/synopsx/files/xsl/tei2html.xsl Stack Trace: - /sites/papiersmmrey/resource/basex/basex.8.4.3/webapp/synopsx/mappings/htmlWrapping.xqm, 78/47 - /sites/papiersmmrey/resource/basex/basex.8.4.3/webapp/synopsx/models/synopsx.xqm, 168/49 - /sites/papiersmmrey/resource/basex/basex.8.4.3/webapp/synopsx/workspace/rey/_restxq/rey.xqm, 443/43 So is it called in the other xsl : <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0" xmlns="http://www.w3.org/1999/xhtml" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs"> <xsl:output method="xml" encoding="UTF-8" indent="no" omit-xml-declaration="yes"/> <xsl:import href="http://rey.huma-num.fr/synopsx/files/xsl/tei2html.xsl"/> [...] And still it is available via a direct GET request : http://rey.huma-num.fr/synopsx/files/xsl/tei2html.xsl Notice that the error code is 502 and not 404. We changed our code as discussed in a previous mail (see below), it seemed to work a little, but now we have this new problem showing... Thanks !

With 8.4, the "raw" output method has become obsolete. Your code should work if you remove the following line: <output:method value='raw'/> Here is yet another solution for the synopsx.files:file() function, which is a bit more compact: function synopsx.files:file($file as xs:string) as item()+ { let $path := $G:FILES || $file return ( web:response-header(map { 'media-type': web:content-type($path) }), file:read-binary($path) ) }; Hope this helps, feel free to ask more questions, Christian

Replacing node sets in a large file
by Michael Sanborn 31 May '16

31 May '16

I need to perform a transformation that would be simple in XSLT, but the input is a file about 250 MBs in size. I'm wondering whether XQuery and BaseX in particular would be the most efficient way of doing it. I'm new to XQuery, and I've come up with a couple of ways to do this, but they turn out to be very time-consuming, so I'm sure I'm Doing It Wrong. Hoping to find out the proper way of doing this. The input consists of 2 sections. There are about 3600 page elements with this structure: <page> [misc page content...] <list> <unit> [misc unit content 1...] <partinfo> <number>54321</number> <manuf>A321</manuf> </partinfo> <partinfo> <number>12345</number> <manuf>B123</manuf> </partinfo> [misc unit content 2...] </unit> [multiple units...] </list> </page> Each unit can have 1 or 2 partinfo elements. The other section has about 82000 part elements like this: <part> <partinfo> <number>54321</number> <manuf>A321</manuf> </partinfo> [misc part content 1] </part> [...] <part> <partinfo> <number>12345</number> <manuf>B123</manuf> </partinfo> [misc part content 2] </part> I want to replace each unit/partinfo with the correpsonding part, like this: <page> [misc page content...] <list> <unit> [misc unit content 1...] <part> <partinfo> <number>54321</number> <manuf>A321</manuf> </partinfo> [misc part content 1] </part> <part> <partinfo> <number>12345</number> <manuf>B123</manuf> </partinfo> [misc part content 2] </part> [misc unit content 2...] </unit> [multiple units...] </list> </page> Is BaseX a good tool for this task? If so, how does one go about it? Finally, it would help to be able to output each page element in a separate file. Would it be better to have BaseX do this, or to output the whole database and chunk it with another tool? Thanks, Michael

HTML5 serialization and @required.
by France Baril 27 May '16

27 May '16

I created forms that use <input *id*=*"browse-to-zip"* *enctype*= *"multipart/form-data"* *name*=*"zip"* *required*=*"required"* *type*= *"file"*/> I was hoping that it would serialize to: <input id="browse-to-zip" enctype="multipart/form-data" name="zip" required type="file">, but I get <input id="browse-to-zip" enctype="multipart/form-data" name="zip" required="required" type="file">. Is it possible to get something well formed to serialize to @required? -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Search algorithm used by BaseX
by Bram Vanroy | KU Leuven 27 May '16

27 May '16

Good afternoon all, It's me again While writing my paper, I was wondering how BaseX (and/or XQuery)'s search algorithm actually works. I imagine each XML-structure is search through one by one, but what technique is used in this search? I'm looking for some terminology such as A*, IDA, D*, depth-first, breadth-first, top down, bottom up, etc. but I cannot find anything in your documentation. Can you enlighten me on the subject? And is the algorithm used specified by BaseX, or is it implied by XQuery? Kind regards Bram Vanroy

Namespace scoping in direct element constructor
by Gunther Rademacher 26 May '16

26 May '16

The order of attributes, including namespace declaration attributes, in a direct element constructor is not significant. But while playing around I found that it makes a difference with BaseX for expressions that are embedded in an attribute. So these two constructors produce different results, but I think it should be the same: basex -q"<e xmlns='A'><e xmlns='B' a='{namespace-uri-for-prefix((), <e/>)}'/></e>" basex -q"<e xmlns='A'><e a='{namespace-uri-for-prefix((), <e/>)}' xmlns='B'/></e>" Tested on BaseX 8.4.1. Best regards Gunther

searching for the nearest ancestor
by Rob Stapper 26 May '16

26 May '16

Hi, While processing a XML-file with xquery I need to find the nearest ancestor that has a child-element with a certain ID-value( $refID). I found this solution [1] but I was wondering if also a solution is possible that makes use of the ancestor being a reverse-axis[ 2]. That way I could replace the [ last()]-predicate with a [1]-predicate, which I find more transparant. Also my gut-feeling tells me that would be a more efficient solution then the current one. [ 1] ( $element/ancestor::*/child::*[ @ID = $refID] ) [ last()] [ 2] https://www.w3.org/TR/xquery-30/#id-predicate TIA for your replies, Take care, Rob Stapper

db:create, language values
by France Baril 26 May '16

26 May '16

Hi, Is it possible to add the list of supported values in the doc for LANGUAGE at: http://docs.basex.org/wiki/Options#Indexing. LANGUAGE *Signature* LANGUAGE [lang] *Default* en *Summary* The specified language will influence the way how an input text will be tokenized. This option is mainly important if tokens are to be stemmed, or if the tokenization of a language differs from Western languages. See Full-Text Index <http://docs.basex.org/wiki/Indexes#Full-Text_Index> for more details. Thanks! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com
