Changes

Database nodes are XML nodes which are either stored in a persistent database, or which contained in are a sonode of a main-called ''memory database fragment''representation. All XML fragments can be converted to a main-memory database fragments by e. g. applying the [[XQuery_Update#update|update]] or [[XQuery_Update#transform|transform]] expression on an XML fragmenta node:

copy $c db:= node-id(element hello { 'world' } modify (update {}) return $c

|{{Func|db:attribute|$db as xs:string, $strings as as xs:string*|attribute()*}}<br/>{{Func|db:attribute|$db as xs:string, $strings as xs:strings*, $name as xs:string|attribute()*}}

|Returns all attribute nodes of the database {{Code|$db}}, the values of which contain one of the specified {{Code|$tokens}}.<br />If {{Code|$name}} is specified, the resulting attribute nodes are filtered by their attribute name.

* Updated: db:output renamed to {{Function|Update|update:output}}, db:output-cache renamed to {{Function|Update|update:output-cache}}
