Changes

==Startup==

First of all, please launch a GUI instance of BaseX. Depending on your operating system, double click on the '''BaseX GUI''' start icon or run the <code>basexgui</code> script. Beside that, some more [[Startup#BaseX GUI|startup options]] are available.

== Create Select ''Database =='' → ''New'' and browse to an XML document of your choice. As an example, you can start with the {{Code|factbook.xml}} document, which contains statistical information on the worlds' countries. It is included in our full releases (in the {{Code|etc}} directory) and can also be [http://files.basex.org/xml/factbook.xml downloaded] (1.3 MB). If you type nothing in the input field, an empty database will be created. Next, choose the ''OK'' button, and the database will be created.

Select ''Database'' → ''New'' and browse If no XML document is available, the [[#Text Editor|Text Editor]] can also be used to create an initial XML document of your choice. As an example, you can start with After saving the {{Mono|factbook.xml}} entered XML documentto disk, which contains statistical information on the worlds' countries. It is included in our official releases and it can also be [http://files.basex.org/xml/factbook.xml downloaded] (1.3 MB)supplied as database input in the above dialog.

Via the ''Options'' menu, you can change the way how queries are executed and visualized[[Image:InputBar.png|Input Bar]]

* '''Realtime Execution''': If realtime execution is enabled, your searches and The upcoming example queries will be executed with each key click and the results will be instantly shown.* '''Realtime Filtering''': If enabled, can 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 ecplicitly filtered used with an instance of the 'Filter' button.[[Category<code>factbook</code> database:GUI]]

== Querying Find==

|<code>worldcity</code>|Find tags elements named {{Code|city}}, and texts containing this token.|-|<code>=India</code>|Find texts matching the exact string {{Code|India}}.|-|<code>~Cing</code>|Find texts equal or similar to the token {{Code|Cingdom}}.|-|<code>id</code>|Find attributes named {{Code|id}} and attribute values containing this token.|-|<code>@=f0_119</code>|Find attribute values matching the exact string {{MonoCode|worldf0_119}}.

|<code>=world"European Chinese"</code>|Find exact matching text nodestexts containing the phrase {{Code|"European Chinese"}}.

|<code>~world//city</code>|Find text nodes similar to 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: {{Mono|world}}class="wikitable"!Query!Description

|<code>@world//country</code>|Find attributes and attribute valuesReturn all <code>country</code> elements.

|<code>@//country[name =world"Switzerland"]</code>|Find exact attribute valuesReturn the <code>country</code> element of "Switzerland".

|<code>"united world"for $city in //city<br/>where $city/population > 1000000<br/>order by $city ascending<br/>return $city/name</code>|Find tags Return the names of all cities with a population larger than one million and texts containing order the results by the name of the phrase {{Mono|"united world"}}city.

=== XPath/XQuery =Command== In the '''Command''' mode, [[Commands|BaseX Commands]] can be entered and executed. Just try the following examples:

Apart from the basic search facilities, BaseX offers far more sophisticated processing options to query your documents* <code>INFO</code>: Returns system information. Below are some examples you might give a try* <code>CREATE DB TEST</code>: Creates an empty database named "TEST". This guide is far from being a comprehensive XQuery reference, but might point you in the right direction* <code>LIST</code>: Lists all databases.

XPath provides an easy facility to query your documents The built-in text editor is a navigational manner. It is the basic helpful tool of all node-related operations for writing [[XQuery]] code that you encounter when using XQueryspans multiple lines or files. We will start with a trivial example It can also be used to edit XML documents, [[Commands#Basics|Command Scripts]], and extend it to our needs.any other textual files:

* XQuery and XML files will be ''' Example: Find Countries 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.

''' Example: Find Cities The Project View is attached to the editor panel. It displays all files of the current project directory in Switzerland '''a tree structure. Files can be renamed and deleted by right-clicking on the files. The project directory can be changed as well; the most recent directories will be kept in the history.

The following query uses a '''predicate''' <code>[All XQuery files in the project directory will be parsed in the background.Buggy XQuery modules, and files importing these modules, will be marked red.With the text fields on top, you can interactively search for file names and contents.]</code> to filter all <code>country</code> nodes which have a <code>name</code> child, the string value of which is "Switzerland":

<pre class="brush:xquery">//country[name Realtime Options= "Switzerland"]</pre>

To return all cities of Via the resulting element node''Options'' menu, the query you can be extended by a trailing <code>//city</code> pathchange how queries are executed and visualized:

<pre class="brush* '''Realtime Execution''':xquery">//country[name = "Switzerland"]//city</pre>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.
