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

A db can only be copied once...
by France Baril 25 May '16

25 May '16

Hi, Since a DB cannot be created dynamically from a restxq call, I'm trying to create some databases by copying an existing one (an empty DB with all the desired parameters). However, it seems that I am unable to create multiple instances from the same DB template. Is there a reason for this limit? I am providing a different target name for each, so technically there shouldn't be any duplicate writing. Any workaround to suggest? Beside the creation of multiple template DB source? Thanks! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

file store question
by Wang, Genneva 25 May '16

25 May '16

Hi BaseX gurus, I noticed that if the resource is persisted in basex, there is a way to tell what type of the resource it is(db:content-type?). However, I’m wondering for new resources to be persisted, is there a way to determine ? Or mostly needs to rely on the application to determine which basex call to be make ? I’m seeing on the document that db:store is to persist binary database and use db:add for other documents. Does it mean that the caller really need to know the type of the resource, in order to determine which db function to call ? Thanks much for your help. Regards, -Genneva

Open Document spreadsheets and column position
by Graydon Saunders 25 May '16

25 May '16

Hi all -- So in Open Document Spreadsheets, columns with empty cells may be collapsed: <table:table-row table:style-name="ro2"> <table:table-cell table:number-columns-repeated="3" table:style-name="ce454" /> <table:table-cell table:style-name="ce255" /> <table:table-cell table:style-name="ce255" office:value-type="string"> <text:p>label</text:p> </table:table-cell> <table:table-cell table:style-name="ce255" office:value-type="string"> <text:p>description</text:p> </table:table-cell> <table:table-cell table:number-columns-repeated="4" table:style-name="ce455" /> </table:table-row> Not all of the rows have have these collapsed empty cells; in some rows, all the cells are present because they've got values in them. And while I wouldn't care in the example row, sometimes more than one table:table-cell represents a collapsed column in a position I care about. All the labels are in column D and all the descriptions in column E (in spreadsheet terms), whether all the table:cell elements are present in the XML representation of the sheet or not, and I need to reliably find them so as to be able to convince myself that the XSLT transform is getting correct answers. (The spreadsheet is about 40 MiB; not so much by recent list standards, but still more than I can hope to read. :) declare function local:realPos($current as node()) as xs:integer { (: the horror, the horror :) xs:integer(path($current) ! tokenize(.,'/')[last()] ! replace(.,'.*\[(\p{Nd}+)\]','$1') ! xs:integer( .) + sum($current/preceding-sibling::table:table-cell/@table:number-columns-repeated) - count($current/preceding-sibling::table:table-cell/@table:number-columns-repeated) ) }; works, in the sense of "will get the cell corresponding to the intended spreadsheet column even when some of the columns have been collapsed with @table:number-columns-repeated". It's horribly slow and it hurts just to look at, though, so -- is there a better way? (The XSLT transform pre-processes all the collapsed table:table-cell elements back into place, among other tidying. I'm not at all sure that's a better way with XQuery.) Thanks! Graydon

Stopping the http server
by France Baril 24 May '16

24 May '16

Hi, A client of mine has multiple users who are able to start/stop the server. The issue though is that the person who starts the server is the only one who can stop it. Some research led to this site that explains how to use secret keys to allow for stopping the server http://www.eclipse.org/jetty/documentation/current/runner.html. Configuring stop You can configure a port number for jetty to listen on for a stop command, so you are able to stop it from a different terminal. This requires the use of a "secret" key, to prevent malicious or accidental termination. Use the --stop-port and --stop-key parameters as arguments to the jetty-runner: > java -jar jetty-runner.jar --stop-port 8181 --stop-key abc123> java -jar jetty-runner.jar --stop-port 8181 --stop-key abc123 Then, to stop jetty from a different terminal, you need to supply the same port and key information. For this you’ll either need a local installation of jetty, the jetty-maven-plugin <http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html>, the jetty-ant plugin <http://www.eclipse.org/jetty/documentation/current/ant-and-jetty.html#jetty…>, or write a custom class. Here’s how to use a jetty installation to perform a stop: > java -jar start.jar --stop-port 8181 --stop-key abc123 --stop> java -jar start.jar --stop-port 8181 --stop-key abc123 --stop In our case, Jetty is started through the BaseX start script. Is there any way we can use a secret key as explained above through the BaseX start/stop server scripts?

add resource from client
by Gilad Wagner 24 May '16

24 May '16

Hi There, I need to load our db from a client xml, the problem is the server cannot reach the client so remote url is not an option. I think I need to use the -I/-i options, but I couldn't find documentation about how to use it. Can you show me a little example? Thank you! Gilad.
