       basex - XML database system and XPath/XQuery processor (command line mode)


       basex [-bcdiLosuvVwxz] [query]


       basex  is  a  fast  and  powerful,  yet light-weight and platform independent XML database
       system and XPath/XQuery processor.


       A short description of option can be obtained from

           $ basex -h

       or by browsing


       A list of supported Database commands can be obtained from

           $ basex -c help

       or by browsing


       ·  XQuery evaluation (no database, no interaction, script mode):

          $ basex -Lq 19+23
          $ basex -Lq "<answer>{ 23+19 }</answer>"

       ·  Import an XML file into database, output its content (query its root) and be verbose:

           $ basex -Vc "CREATE DB input /usr/share/doc/basex/examples/input.xml; XQUERY /"
           Database 'input' created in 136.84 ms.
             <!-- Header -->

           Query executed in 42.52 ms.

       ·  XPath evaluation (with existing database):

           $ basex -Lc "OPEN input; XQUERY //li[1]"
           <li>Exercise 1</li>

       ·  Retrieve XML from the web and perform XPath query:

           $ basex -Lq "doc('')//li"
           <li>Exercise 1</li>
           <li>Exercise 2</li>

       ·  W3C XQuery Full-Text (make use of full-text index and perform fuzzy query with a typing

           $ basex
           BaseX 7.1 [Standalone]
           Try "help" to get more information.

           > SET FTINDEX on
           Full-Text Index: ON
           > CREATE DB input /usr/share/doc/basex/examples/input.xml
           Database 'input' created in 94.42 ms.
           > XQUERY //b[text() contains text 'Asisgnment' using fuzzy]
           Query executed in 8.37 ms.

       ·  Update the database and show result:

           > XQUERY delete node //ul
           Query executed in 2.79 ms.
           > XQUERY replace value of node //b with 'Debian rules'
           Query executed in 2.94 ms.
           > XQUERY //div
           <div align="right">
             <b>Debian rules</b>
           Query executed in 1.01 ms.

       ·  Open an input xml file, execute a query and write result into file:

           $ basex -Li /usr/share/doc/basex/examples/input.xml -q //div -o out.xml
           $ cat out.xml
           <div align="right">
               <li>Exercise 1</li>
               <li>Exercise 2</li>

       ·  Query  an  already  existing database called 'input'. If a file named 'input' exists in
          current working directory it takes precedence:

           $ basex -Li input -q //div
           <div align="right">
               <li>Exercise 1</li>
               <li>Exercise 2</li>

       ·  Let basex process query input from standard in:

          $ echo '19+23' | basex -Lq-

       ·  Execute commands from script file:

          $ cat commands.txt
          create db debian <debian_db/>
          xquery /
          $ basex -LC commands.txt | grep debian
          debian              1          4639       debian.xml

       ·  Parse non well-formed HTML (needs libtagsoup-java installed):

          $ cat bad.html

          $ basex -c 'set parser html; set htmlopt method=html,nons=true; create db htmldb bad.html'
          $ basex -q "doc('htmldb')"

       BaseX Documentation Wiki:


       BaseX started as a research project of the Database and Information Systems  Group  (DBIS)
       at  the University of Konstanz in 2005 and soon turned into a feature-rich open source XML
       database and XPath/XQuery processor.
