testing of updating functions in basex
by dudzikp＠yahoo.com 18 Nov '20

18 Nov '20

Dear all, I have not found a way to make basex unit module to test updating functions. I have a function site:add-movies which results in several db:add instructions. I try to achieve something like: declare %unit:test %updating function test-site:download-movies() { let $result := site:add-movies( $test-site:site-db, test-site:fake-fetch-file#1, 7 ) return unit:assert-equals(1, 1) (: here I am going to check if db contains expected elements :) }; But let command is not valid for updating expression. Basex docs mention something about update:output and update:cache which may be of some use here but no exhaustive example is given for. Anyone had similar problem? BR

importing data from powershell
by Nicholas 18 Nov '20

18 Nov '20

for some simple data as: PS /home/nicholas> PS /home/nicholas> $data = @{ >> customer = 'something' >> name = 'whatever' >> } PS /home/nicholas> PS /home/nicholas> ($data | ConvertTo-Xml).OuterXml <?xml version="1.0" encoding="utf-8"?><Objects><Object Type="System.Collections.Hashtable"><Property Name="Key" Type="System.String">name</Property><Property Name="Value" Type="System.String">whatever</Property><Property Name="Key" Type="System.String">customer</Property><Property Name="Value" Type="System.String">something</Property></Object></Objects> PS /home/nicholas> what would be some different ways of importing this data into BaseX? Certainly, the above XML can simply be written to a file, but what might something, from within powershell, a bit more automated? thanks, Nick

Hi, /data() is printed as - , while "-” as - (even if both are xs:string): is there a reason? In any case, is there a function to convert  into - ? Thanks. Best, Giuseppe

BaseX GUI and remote editing
by Marco Lettere 16 Nov '20

16 Nov '20

Hello all! We are in the slightly uncomfortable condition to do some remote coding. Means write XQ code that has to be kept on a server different from our PCs. We don't want to slow down our very agile development workflow by passing everytime from a Git repo ... Has anyone here some experience with remote editing of this kind? Using BaseX Gui is out of discussion, isn't it? Thanks, Marco.

Dr. Mike Kay's proposals for XPath and XQuery 4.0
by Bridger Dyson-Smith 16 Nov '20

16 Nov '20

Hi all - I imagine that Dr. Kay has posted about this in multiple places, but I don't know if he's posting on the BaseX list much. He shared the following links with his thoughts on XPath, XSLT, XQuery, and F&O version 4.0 [1] - I don't know how many implementers we have on this list, outside of Christian and co., but thought you all might find it interesting. Hope everyone is having a lovely day. Best, Bridger PS I found this announcement on the XML.com Slack channel, fyi. [1] Mike Kay's post from Slack: I've been working on fleshing out my ideas for XSLT/XPath 4.0, based on my XML Prague paper earlier this year. I'm hoping to gather together a community group of some kind to take this forward; meanwhile I've published a very preliminary set of drafts: XSLT: https://www.saxonica.com/qt4specs/XT/Overview-diff.html F&O: https://www.saxonica.com/qt4specs/FO/Overview-diff.html XPath: https://www.saxonica.com/qt4specs/XP/xpath-40-diff.html XQuery: https://www.saxonica.com/qt4specs/XQ/xquery-40-diff.html Preparing for the rotten tomatoes: let me know what you think and whether you want to participate. NOTE: each document has a summary of changes at the end. It's probably best to go there first.

Bind context to stdin: -i-
by Majewski, Steven Dennis (sdm7g) 14 Nov '20

14 Nov '20

I just thought I would share this, as it was non-obvious to me. I wanted to use xpath expressions in a shell script pipeline, and was looking to see if there was a way to bind context to stdin. It wasn’t clear from the documentation, so I just tried the common convention of using “-“ and: Pipeline commands producing XML output “| basex -i- “ followed by a path or query works! And it works better that the PERL xpath command. — Steve Majewski

grouping by fuzzy match?
by Graydon Saunders 12 Nov '20

12 Nov '20

Hello -- Is there some way to assign the abstraction of a fuzzy match to a variable, so that something like for $x in //p let $key := get-fuzzy-match-value($x) group by $key return <similar-paragraphs>{$x}</similar-paragraphs> would be possible? I'm supposing this is one of those things that's either easy or impossible. Thanks! Graydon

Progress bar
by Giuseppe G. A. Celano 11 Nov '20

11 Nov '20

I have written a BaseX script (which applies a few functions to files in a directory), which I run at the command line. Is there a "trick" to get a progress bar for that (other than calling BaseX from a different programming language having some progress bar library)? Thanks. Best, Giuseppe

Versioning in BaseX
by Rob 10 Nov '20

10 Nov '20

Hi all, I first created an Github Issue for this question, but that’s not the right play :) So hereby my question: I was wondering how versioning works in BaseX. So I have a XML file, I store another version of that same XML file and within BaseX there is some kind of versioning so I can retrieve both versions of the XML file. I look into your mail archive, and I found the following mail: https://www.mail-archive.com/basex-talk@mailman.uni-konstanz.de/msg07369.ht… <https://www.mail-archive.com/basex-talk@mailman.uni-konstanz.de/msg07369.ht…> Here it states that with using database metadata (Database Module, https://docs.basex.org/wiki/Database_Module <https://docs.basex.org/wiki/Database_Module>), you can achieve versioning. But I don't see anything about it in the documentation. So I was wondering if it is a thing in BaseX (versioning), and how it's accomplished 👍 Thanks! Kind regards, Rob Tjalma
