Database driver XML

Overview

This guide provides instructions on how to set up and use XML files with Team Edition. The XML driver supports standard XML files, including both attribute-based and nested element-based structures. You can retrieve data and apply filters, sorting, and other operations, even combining data from multiple files.

Important: When using the XML driver, all connected XML files are read-only. To make changes, you need to update the original files outside Team Edition.

XML Files driver connection

This section describes two ways to set up a connection: opening a file from Cloud Storage or creating a connection using the wizard.

Note: The connection from Cloud Storage is temporary and will be removed when the session ends.

Open a file from Cloud Storage

You can open files directly from your Cloud Storage. Open Cloud Storage, find the file you need, and double-click it to create a connection. The connection will appear in the File databases folder in Database Navigator.

You'll need to be logged in using the Identity Provider associated with your Cloud Storage.

Create a connection

To create a connection in Team Edition, use the new connection wizard, select the XML driver, and fill the following fields:

Field	Description	Options
Configuration	Choose how to specify the connection details.	- Manual: Enter the database path manually. - URL: Provide a connection URL.
Database	Enter the file/folder path.	Use the appropriate format for your cloud provider. For instance: s3://AWS/files/path/example/
Connection name	Enter a custom name for your connection.	Defaults to XML@localhost.
Description	(Optional) Add details about this connection.
Keep alive (in seconds)	Set how long the connection stays active.	Default: 0 (no timeout).
Auto commit	Enable automatic transaction commits. See more details on Auto and Manual commit modes.	Enabled by default.
Read-only connection	Restrict the connection to read-only mode.	Optional checkbox.

Tip: When using the folder path in the Database field, Team Edition scans the directory up to two levels deep for supported files. If the folder contains multiple files, Team Edition organizes them into schemas based on their directory structure. For more information, see folder structure.

Features and capabilities

Advanced SQL query capabilities

The XML driver supports the full range of SQL queries:

• Simple queries (e.g., SELECT * FROM table): Data is read directly from the XML file.
• Complex queries (e.g., using WHERE, JOIN, ORDER BY, GROUP BY): When a complex query is executed for the first time, the driver imports the entire XML file into an internal database to enable advanced SQL functions. Subsequent queries run faster because the data is already imported into internal database.

Note: If you want to join data from different files, they must be opened in the same connection. To do this, use a folder path instead of a single file when creating the connection.

Folder structure

When working with a folder containing multiple XML files, Team Edition organizes them as follows:

Folder structure	Schema in Team Edition
Root files	Default schema
Subfolder files	Schema named after the subfolder
Files in deeper folders	Ignored

If your folder looks like this:

Data/
├── employees.xml
├── sales.xml
└── Reports/
    └── monthly.xml
    └── yearly.xml

Team Edition will create:

• Default schema: employees, sales
• Reports schema: monthly, yearly

Tip: To focus on specific files, consider selecting individual files or folders when configuring the connection.

Internal database

When you execute a complex query (such as WHERE, JOIN, GROUP BY, or ORDER BY.), on an XML file for the first time, the XML driver processes the data by importing it into a temporary internal SQLite database.

This internal database stores data temporarily on the server during your session and is cleared when session ends.

Additional features
