EXAMPLES

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

          $ basex 19+23
          42
          $ basex -q "<answer>{ 23+19 }</answer>"
          <answer>42</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.
           <html>
             <!-- Header -->
             <head id="0">
               <title>XML</title>
             </head>
             <!-- Body -->
             <body id="1" bgcolor="#FFFFFF" text="#000000" link="#0000CC">
               <h1>Databases &amp; XML</h1>
               <div align="right">
                 <b>Assignments</b>
                 <ul>
                   <li>Exercise 1</li>
                   <li>Exercise 2</li>
                 </ul>
               </div>
             </body>
             <?pi bogus?>
           </html>

           Query: /

           Compiling:

           Result: root()

           Parsing: 5.08 ms
           Compiling: 27.2 ms
           Evaluating: 0.87 ms
           Printing: 13.7 ms
           Total Time: 46.86 ms

           Hit(s): 1 Item
           Updated: 0 Items
           Printed: 358 Bytes

           Query executed in 42.52 ms.

       ·  XPath evaluation (with existing database):

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

       ·  Retrieve XML from the web and perform XPath query:

           $ basex -q "doc('http://files.basex.org/examples/input.xml')//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
          error):

           $ 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]
           <b>Assignments</b>
           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>
           </div>
           Query executed in 1.01 ms.

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

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

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

           $ basex -i input -q //div
           <div align="right">
             <b>Assignments</b>
             <ul>
               <li>Exercise 1</li>
               <li>Exercise 2</li>
             </ul>
           </div>

       ·  Let basex process query input from standard in:

          $ echo '19+23' | basex -q-
          42

       ·  Execute commands from script file:

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

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

          $ cat bad.html
          <html>
            <ul>
              <li>A
              <li>B
            </ul>
          </html>

          $ basex -c 'set parser html; set htmlopt method=html,nons=true; create db htmldb bad.html'
          $ basex -q "doc('htmldb')"
          <html>
            <body>
              <ul>
                <li>A</li>
                <li>B</li>
              </ul>
            </body>
          </html>

          Alternative:

          $ basex -q 'declare option db:parser "html"; doc("bad.html")'
          <html xmlns="http://www.w3.org/1999/xhtml">
            <body>
              <ul>
                <li>A</li>
                <li>B</li>
              </ul>
            </body>
          </html>

HISTORY

       BaseX started as a research project of the Database and Information Systems  Group  (DBIS)
