[basex-talk] example .basexperm files please

[pw]

hello list
are there any examples of .basexperm files?  what form are the
permissions in?  [i.e. 0777, or -rwxrwxrwx, or some other form] Is
the separator a space or a tab? [does it matter?]

thanks

Pete

Re: [basex-talk] Initial xquery for full text and geospatial search of ISO 19115 docs

[Christian Grün]

Hi David,

due to the complexity of XQuery, it’s often a big challenge for the
query optimizer to find out if an index can be used or not. This is
the reason why some XML database don’t even try to rewrite queries for
index access.

What you can always do is: directly address the available index
structures via the Full-Text and Index modules [1,2]. This will give
you the guarantee that the index is indeed utilized.

I'm sure there are also ways to rewrite your existing query in order
to ensure index access, but I’d first need some more time to get into
this. As a general note, you can help the optimizer by directly
specifying the addressed database in your query. The following two
examples may illustrate this. Query A und B will be optimized for
index access, while Query C won’t (well, at least not in BaseX ≤ 7.5):

Query A
  db:open("db")//*[text() contains text { "A","B" }]

Query B
  let $terms := ("A", "B")
  for $x in db:open("db")//*
  where $x/text() contains text { $terms }
  return $x

Query C
  declare function local:x($db, $terms) {
db:open($db)//*[text() contains text { $terms }]
   };
  let $terms := ("A", "B")
  let $db := "db"
  return local:x($db, $terms)

Best,
Christian

Re: [basex-talk] Initial xquery for full text and geospatial search of ISO 19115 docs

[David Stuebe]

Hi Chris

I did look at the Query Info in the Gui and it seems you are correct. The 
complex query I created is not utilizing the full text index.

Details here:
https://gist.github.com/4438473

The gist contains query info for the complex search that I created and for a 
simple one that just executes the 'contains text' clause.

The compile statement for the simple query includes the following line: 
"applying full-text index"
The complex query does not…


So what to do now? How do I figure out why basex is not using the full text 
index as the initial step in limiting the results of my search?

Thanks

David

Hi David,

thanks for the insight into your project. It may be that the full-text
index is not utilized by your XQuery expression. Did you have a look
at the query info (e.g. via GUI, InfoView, or -V on command line)? Did
you manage to write simpler queries that are processed faster?

Best,
Christian

Re: [basex-talk] Fwd: concat string in for loop

[Christian Grün]

Cześć, Jaroslwy,

as XML serialization was originally not built for outputting text, the
handling of whitespaces is a little tricky. However, you can benefit
from the new XQuery 3.0 "item-separator" output option:

  declare option output:item-separator '\n';
  concat("text",'
',"additional text"),
  element-aelement-b/*/string()

If you want to stick with XQuery 1.0, you can try string-join():

string-join((
  "text", "additional text",
  element-aelement-b/*
), '
')

[basex-talk] Fwd: concat string in for loop

[Jarosław Kowalewski]

Hi,

I've a problem with concatation strings in for loop.

e.g. xquery


concat("text",'
',"additional text"),
'
',
'
',

for $i in element-aelement-b/*
return concat($i,'
')


give me the result

"
text
additional text

 element-a
 element-b
"

with additional space before "element-a" and "element-b" but the
concatation in the first row works fine. I tried it in GUI mode
version 7.3 and 7.5.

Thank you once again Christian for your fast reply, and update !

BaseX is a fantastic XML tool.
Wondering how I could process XML before !

As night time is also dream time,
Do you still plan to increase database node count limitation for the next major

good point, there was no way to do so.. but this has changed with the latest 
snapshot. You will get the value for UPDINDEX, MAXCATS and MAXLEN by either 
running the commands "open ...; info db" or evaluating the XQuery function 
"db:info('...')".

The GET command will always give you the global value of an option.

Re: [basex-talk] Either db:replace() or I had too much to drink this XMas

[Christian Grün]

;) ..hi France,

it may take us a while to reproduce what’s going on in your code, so..
do you think you could further simplify your example? Or, ideally,
minimize it to a simple db:replace() function?

You could check the consistency of your database via the INSPECT
command [1] before and after running your query.

good point, there was no way to do so.. but this has changed with the
latest snapshot. You will get the value for UPDINDEX, MAXCATS and
MAXLEN by either running the commands "open ...; info db" or
evaluating the XQuery function "db:info('...')".

The GET command will always give you the global value of an option.

Thanks,
Christian

[basex-talk] Either db:replace() or I had too much to drink this XMas

[France Baril]

Hi, I am having issues with updating functions in BaseX 7.5 (official
release).


When I update a document, its content is updated with the content of
another document.


I even perform the db:optimized in a separate function after a forward to
ensure that the db:replace is in fact completed before indexes are
optimized.

*
*

To replicate: you'll need a db named 'en-us' with the 3 following documents
(file names don't matter):





Then use these functions:

*
*

*declare* %rest:path("/admin/refresh-menu-headings")
   %rest:GET
   %rest:query-param("menu-id", "{$menu-id}", "devicehelp")
   *updating* *function* *admin:refresh-menu-headings*(*$menu-id* *as **
xs:string*){

  (:Get the content:)
   *let* *$raw-menu* := *app:open-db*('en-us')/*menu*[*@id* = *$menu-id*
]

  (:Get the file location:)
   *let* *$menu-uri* := *substring-after*(*$raw-menu*/*base-uri*(),
'en-us/')

  (:Copy the content:)
*let* *$menu* := *$raw-menu*

*   (:Output the content in a file to ensure you have the right one:)*

*   **let* *$debug* := *file:write*('debug-ouch.xml', *document*{*$menu*
})

  (:Output the file uri to ensure you have the right one:)

*let* *$debug-uri* := *file:write*('debug-uri.xml', *$menu-uri*)

   (:Replace the content of the file with the same content that was
outputted in debug-ouch:)
*return *(*db:replace*('en-us', *$menu-uri*, *$menu*),
  *db:output*(
/restxq/admin/success/heading-refresh))

};


*declare* %rest:path('/admin/success/heading-refresh')
*updating* *function* *admin:success-heading-refresh*(){
*let **$result* := http://www.w3.org/1999/xhtml"*>
   Add headings to menu topicrefs

   
  Add headings to menu topicrefs
  
 Menus were
updated successfully.
  
   
  
   *return *(*db:optimize*('en-us'), *db:output*(*$result*))


RESULT:
The result after optimize if your query for a list of the /menu/data(@id)
should be devicehelp, smbonly, ptt-help, but it's ptt-help, smbonly,
ptt-help.

debug-ouch.xml shows the correct content (content of menu devicehelp),
debug-uri shows the right file path (path of menu ptt-help), yet the
content of menu with @id devicehelp gets replaced by the content of menu
with @id=ptt-help after db:replace.

Note: If I use db:optimize('en-us', true()), I get 'unexpected error: 0'

[basex-talk] UPDINDEX

[pw]

Hello List

I am working with 7.5 and am looking for guidance on setting UPDINDEX

If I run the basex http server from the command line and GET UPDINDEX
it is initially false.  If I then open the client and GET UPDINDEX it
is also false (as expected).  Through the client I can then set it
with the command "set updindex true".  This time GET UPDINDEX returns
true through the client but false through the httpserver.  

How do I set the updindex option so that it it operational for the
REST service?

Thanks

Peter

Re: [basex-talk] how to pass raw bytes intact?

[Christian Grün]

As Liam indicated (thanks!), XQuery may not be the best choice to
process data on byte level: XQuery was built to work with Unicode
characters as basic unit, which means that it will never be possible
with pure XQuery to create illegal UTF8 sequences. This also means
that the language provides no support to „repair” invalid input.

I wonder if you have enough control over your input to avoid UTF8
shattering? If there’s no choice, and if you still want to try
XQuery/BaseX for byte processing, you can play around with the
functions of the Conversion Module:

Re: [basex-talk] XQuery Update using IF Condition...

[Christian Grün]

Hi John,

all branches of your if expression must be updating, or return an
empty sequence. In the latest snapshot [1], I’ve replaced the old
error message with a more helpful one (“all expressions must be
updating or return an empty sequence.”).

To come back to your query: The following query will be accepted:

  for $c in doc('2012')/Docs/Doc/No/@n
  return
if(doc('Data')/Docs/Doc[No/@n=$c]/Title/Name/text())
then insert node $c into doc('Data')/Docs
else ()

The following query does the same:

  for $c in doc('2012')/Docs/Doc/No/@n
  where doc('Data')/Docs/Doc[No/@n=$c]/Title/Name/text()
  return insert node $c into doc('Data')/Docs

If you want to return some textual output for all nodes that have not
been updated, you can use db:output() [2]:

  for $c in doc('2012')/Docs/Doc/No/@n
  return
if(doc('Data')/Docs/Doc[No/@n=$c]/Title/Name/text())
then insert node $c into doc('Data')/Docs
else db:output({''})

Hope this helps,
Christian

[basex-talk] how to know creation options of a database

[Fabrice Etanchaud]

Dear all at BaseX,

How can I know the creation options of a given database ?

When I open a database created with a few non default options (MAXCATS set to 
1) for example,
GET MAXCATS seems to  always return the last value set with SET MAXCATS.
