BaseX
by Hans-Juergen Rennau 11 Jan '17

Dear BaseX team - no bug, no question, no feature request - only the urge to thank you for your work. About a year ago I embarked on a piece of research work which has kept me busy and excited ever since. This work is important to me because so much seems to go into it, of what I have come to think and be convinced of in the course of several years. At every step, BaseX has been my tool to turn ideas into reality. It has not failed me once, in spite of heavy use of advanced features like function items and partial function invocations. And several times I was so glad to find that BaseX offered exactly the extensions I needed. I think BaseX has achieved an admirable combination of standard conformance and reliability, on the one hand, and bold and generous extension on the other hand. So, summing up - thank you very much.

fn:doc weirdness with imported files
by Marc van Grootel 11 Jan '17

11 Jan '17

Hi all, Happy new year btw! I got bitten by something and can't explain this behaviour. So the situation is that I have an XML file on the file system in F:/tmp/foo.xml I also have this file imported into a database named "foo" (and the path "/foo.xml". Now in the GUI (and on 8.5.3) I have the following. When I have the database closed in the GUI base-uri(doc('F:/tmp/foo.xml')) => file:///F:/tmp/foo.xml And when I open the database "foo" from the GUI base-uri(doc('F:/tmp/foo.xml')) => /foo/foo.xml Is that right? Also db:* functions also get a database node from the latter and return a node-id for example. When the foo.xml is moved to another filesystem directory then this doesn't happen so it appears as if this happens only when I try to read the file from the original import location. Shouldn't these two situations have the same result? Cheers, --Marc

Async unit testing
by Andy Bunce 05 Jan '17

05 Jan '17

Hi, Around version 7.8 there was a function that allowed unit tests to be invoked from XQuery: unit:test-uris($uris as xs:string*) as element(testsuites) Later this was removed, but ability to run updating tests was added. Which was great. I wonder how easy it would be, using the jobs module, to implement a function as below? jobs:test-uris($uris as xs:string*, $options as map(xs:string, xs:string)) as xs:string Asynchronously runs all functions in the specified modules that have unit annotations.A test report is generated and optionally cached, which resembles the format returned by other xUnit testing frameworks, such as the Maven Surefire Plugin. returns a job id /Andy

XML Prague Meeting... Postponed
by Christian Grün 04 Jan '17

04 Jan '17

Dear all, This year, there will be no BaseX Preconference Meeting in XML Prague. Sorry for that! The reason is simple: We were too busy in order to prepare ourselves for the event, look for speakers, etc. At least we are happy to announce that BaseX 8.6 will finally be released this month. Stay tuned! All the best, Christian

archive:entries - no representation of empty folders
by Hans-Juergen Rennau 03 Jan '17

03 Jan '17

Dear BaseX team, a question concerning the reading of archive files (e.g. .zip) via archive:entries. If I don't overlook something, the read function archive:entries returns one <archive:entry> per file contained in the archive. Folders containing files (directly or recursively) can be inferred, but empty folders cannot be inferred, and therefore it is not possibly to extract the contents of archives in a reliably complete way: any empty folders are ignored. Is that correct? If so, are there plans to add support for the retrieval of empty folders? Personally, I think the ability to unpack archives completely is important, for example because subsequent operations may fail in the absence of the expected folder. One conceivable solution would be to return for each empty folder an entry with an additional attribute: <archive:entry isFolder="true" .../>. Cheers,Hans-Jürgen

Namespaces in element constructors
by Bridger Dyson-Smith 02 Jan '17

02 Jan '17

Hi all - I think that I weak grasp of the practical requirements, but I'm unable to find a reference in the spec to clarify what's happening in the following: I have a constructor: return( for $item in $file-list let $item-less := replace($item, '^\d{1,}-', '') (: returns "missing" supplemental files :) where ($item-less[(not(. = ($files-titles, $excludes)))]) or ($item-less[(. = $files-titles)]) return( <relatedItem> <title>{$item-less}</title> <mimeType> {if ($item-less = $files-titles) then ($content/files/file/name[. = $item-less]/following-sibling::mimetype/text()) else (fetch:content-type(concat(file:parent(document-uri($doc)),$item)))} </mimeType> <uri>{file:parent(document-uri($doc))}</uri> </relatedItem> ) ) and it works fine so long at the <relatedItem> is not namespaced. As soon as the <relatedItem> is namespaced; e.g. <relatedItem xmlns=" http://bridger.net">, then I need to use the following XPath in the `then` keyword: ($content/*:files/*:file/*:name[. = $item-less]/following-sibling::*:mimetype/text()) The input documents (in the SSCCE, under sample-data/*/metadata.xml) are not in a namespace. Would someone mind providing some context for the "why" here? I've been looking through Priscilla Walmsley's 2nd edition, and the specification, but haven't been able to find an answer. I'm almost certainly looking for the wrong thing(s). Any help will be greatly appreciated! Thank you in advance. Best, Bridger

Schema Validation issues
by George Sofianos 02 Jan '17

02 Jan '17

Because of issues with schema validation (can't properly use doc() in the validate function - see https://github.com/BaseXdb/basex/issues/1324) I'm not using BaseX to do schema validation in my workflow. But I needed it today to make some result comparisons with my own implementation of XML Validator, and I noticed that using the beta Xerces version which is documented in the wiki <http://docs.basex.org/wiki/Validation_Module#XML_Schema_Validation> can make it crash, so I thought I should report it here. Other than that, I noticed one some XML files that it only reports fatal errors, and hides any other non-fatal error. I think it has something to do with the process <https://github.com/BaseXdb/basex/blob/86a12cf0c75010b3058c18f81c4689bc511b7…> method but I'm not sure.

TagSoup and html5 support
by Alexander Shpack 21 Dec '16

21 Dec '16

Hi team! As you know, TagSoup 1.2.1 doesn't support correct HTML5 tag nesting. For example, this string Test will be parsed as But html5 code <aside>Test</aside> will be parsed as is. How to implement in BaseX the html5 support? I've found this project, but not sure that it's possible to add it into basex code https://github.com/UniversityofWarwick/tagsoup-html5 Thanks!
