Changes

Please be warned that the new default can throw off existing applications. If you want to restore the old behavior, you should attach the following lines in your [[Configuration|.basex configuration file]]…

# Local Options

STRIPWS = true

…or add context parameters in the {{Code|web.xml}} file of your [[Web Application]]:

<context-param>

<param-name>org.basex.stripws</param-name>

Note that {{Option|STRIPWS}} only applies to stored XML and not to XML constructed within XQuery source files. Within XQuery code, the standard {{Code|boundary-space}} setting applies. This defaults to {{Code|strip}}. To preserve XML whitespace in XQuery modules, add the following to the prolog:

declare boundary-space preserve;

<xml> </xml>

The new feature can e.g. be used to store maps in a database:

db:put-value(

'factbook',

…and use them as index later on:

let $cities := db:get-value('factbook', 'cities')

for $country in ('Japan', 'Indonesia', 'Malaysia')

Lock detection will be performed after the first step, and the code resulting from this step offers much more insight into which specific databases need to be locked. As a result, local locks can be applied to many more queries than before, and many queries can now run in parallel. An example:

declare variable $n external;

db:get('names-' || $n)

XQuery Update provides constructs to [[XQuery Update#Main-Memory Updates|update XML nodes in main memory]]. The data structures for in-memory representations of XML resources have been revised, such that updates can be performed orders of magnitudes faster than before. With BaseX 9.x, the following query runs for several minutes, whereas it can now be computed in a few seconds:

<xml>{

(1 to 1000000) ! <child/>

; Store data:

let $email := map:merge(

for $address in db:get('addressbook')//address

; Retrieve data:

let $name := 'Richard David James'

return store:get('email')($name)

Results in the {{Code|rest}} namespace are now returned without prefix:

<!-- before -->

<rest:databases xmlns:rest="http://basex.org/rest"/>
