Graphical User Interface
This page is part of the Getting Started Section. The BaseX homepage gives you a visual impression of the graphical user interface (GUI) of BaseX, and an introductory video is available, which presents some of its interactive features.
Startup
First of all, launch a GUI instance of BaseX. Depending on your operating system, double click on the BaseX GUI start icon or run the basexgui
script. Beside that, some more startup options are available.
Create Database
Select Database → New and browse to an XML document of your choice. As an example, you can start with the factbook.xml
document, which contains statistical information on the worlds' countries. It is included in our official releases and can also be downloaded (1.3 MB). If you type nothing in the input field, an empty database will be created. Next, choose the OK button, and BaseX will create a database that you can visually explore and query.
If no XML document is available, the Text Editor can also be used to create an initial XML document. After saving the entered XML document to harddisk, it can be supplied as database input in the above dialog.
Input Bar
On top of the main window, you can find an input bar. The attached dropdown menu provides three modes: Find, XQuery and Command:
The upcoming example queries can all be used with an instance of the factbook
database:
Find
In the Find mode, the input bar can be used to find single elements and texts in the currently opened database. The following syntax is supported:
Query | Description |
---|---|
city
|
Find elements named city , and texts containing this token.
|
=India
|
Find texts matching the exact string India .
|
~Cing
|
Find texts equal or similar to the token Cingdom .
|
id
|
Find attributes named id and attribute values containing this token.
|
@=f0_119
|
Find attribute values matching the exact string f0_119 .
|
"European Chinese"
|
Find texts containing the phrase "European Chinese" .
|
//city
|
Leading slash: Interpret the input as XPath expression (see below). |
XQuery
In the XQuery mode, XPath and XQuery expressions can be entered in the input bar.
To evaluate the following example queries: enter them in the input bar, and press ENTER or click on the START button:
Query | Description |
---|---|
//country
|
Return all country elements.
|
//country[name = "Switzerland"]
|
Return the country element of "Switzerland".
|
for $city in //city
|
Return the names of all cities with a population larger than one million and order the results by the name of the city. |
Command
In the Command mode, BaseX Commands can be entered and executed. Just try the following examples:
INFO
: Returns system information.CREATE DB TEST
: Creates an empty database named "TEST".LIST
: Lists all databases.
Text Editor
The powerful text editor can be used to write and edit XQuery code (simple queries, modules), XML documents, Command Scripts, and any other textual files:
- XQuery and XML files will be parsed with each key click, and errors will be highlighted.
- XQuery and command scripts can be executed by clicking on the green triangle.
- Syntax highlighting is available for XQuery, XML, JSON and JavaScript files.
Numerous keyboard shortcuts are available to speed up editing and debugging.
Project View
The Project View is attached to the editor panel. It displays all files of the current project directory in a tree structure. Files can be renamed and deleted by right-clicks on the files. The project directory can be changed by clicking on the button with the three dots ...
in the upper left corner of the project view panel.
Erroneous XQuery modules, and all queries importing these modules, will be highlighted. Highlighting can be disabled in the GUI preferences dialog.
Realtime Options
Via the Options menu, you can change how queries are executed and visualized:
- Realtime Execution: If realtime execution is enabled, your searches and queries will be executed with each key click and the results will be instantly shown.
- Realtime Filtering: If enabled, all visualizations will be limited to the actual results in realtime. If this feature is disabled, the query results are highlighted in the visualizations and can be explicitly filtered with the 'Filter' button.
Visualizations
The BaseX GUI offers various visualizations, which help you to explore your XML data instances from different perspectives:
