NAME
basex - XML database system and XPath/XQuery processor (command line mode)
SYNOPSIS
basex [-bcdiLosuvVwxz] [query]
DESCRIPTION
basex is a fast and powerful, yet light-weight and platform independent XML
database system and XPath/XQuery processor.
OPTIONS
A short description of option can be obtained from
$ basex \-h
or by browsing http://docs.basex.org/wiki/Startup_Options#BaseX_Standalone
DATABASE COMMANDS
A list of supported Database commands can be obtained from
$ basex \-c help
or by browsing http://docs.basex.org/wiki/Commands
EXAMPLES
* XQuery evaluation (no database, no interaction, script mode):
$ basex \-Lq 19+23
42
$ basex \-Lq "<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 & 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 \-Lc "OPEN input; XQUERY //li[1]"
<li>Exercise 1</li>
* Retrieve XML from the web and perform XPath query:
$ basex \-Lq "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 \-Li /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 \-Li 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 \-Lq\-
42
* Execute commands from script file:
$ cat commands.txt
create db debian <debian_db/>
xquery /
list
$ basex \-LC 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>
