How to Create Power BI Visual Reports with Real-Time XML Data

CData Power BI Connectors provide self-service integration with Microsoft Power BI. The CData Power BI Connector for XML links your Power BI reports to real-time XML data. You can monitor XML data through dashboards and ensure that your analysis reflects XML data in real time by scheduling refreshes or refreshing on demand. This article details how to use the Power BI Connector to create real-time visualizations of XML data in Microsoft Power BI Desktop.

If you are interested in publishing reports on XML data to PowerBI.com, refer to our other Knowledge Base article.

Collaborative Query Processing

The CData Power BI Connectors offer unmatched performance for interacting with live XML data in Power BI due to optimized data processing built into the connector. When you issue complex SQL queries from Power BI to XML, the connector pushes supported SQL operations, like filters and aggregations, directly to XML and utilizes the embedded SQL Engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze XML data using native Power BI data types.

Connect to XML as a Power BI Data Source

Installing the Power BI Connector creates a DSN (data source name) called CData Power BI XML. This the name of the DSN that Power BI uses to request a connection to the data source. Configure the DSN by filling in the required connection properties.

You can use the Microsoft ODBC Data Source Administrator to create and configure the DSN: From the Start menu, enter "ODBC Data Sources" and select the CData PowerBI REST DSN. Ensure that you run the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit). You can also use run the ConfigureODBC.exe tool located in the installation folder for the connector.

Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) XML Files

CData Drivers let you work with XML files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

Setting connection properties for local files

Set the URI property to local folder path.

Setting connection properties for files stored in Amazon S3

To connect to XML file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended XML files exist. In addition, at least set these properties:

• AWSAccessKey: AWS Access Key (username)
• AWSSecretKey: AWS Secret Key

Setting connection properties for files stored in Box

To connect to XML file(s) within Box, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Box.

Dropbox

To connect to XML file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

SharePoint Online (SOAP)

To connect to XML file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. Set User, Password, and StorageBaseURL.

SharePoint Online REST

To connect to XML file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

Google Drive

To connect to XML file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

The property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

• Document (default): Model a top-level, document view of your XML data. The data provider returns nested elements as aggregates of data.
• FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
• Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

See the Modeling XML Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

How to Query XML Tables

Follow the steps below to build a query to pull XML data into the report:

1. Open Power BI Desktop and click Get Data -> Other -> CData XML.
2. Select CData PowerBI XML in the Data Source Name menu and select a data connectivity mode:
   Select Import if you want to import a copy of the data into your project. You can refresh this data on demand.
   Select DirectQuery if you want to work with the remote data.
3. Select tables in the Navigator dialog. 👁 The available tables. (Salesforce is shown.)
   

4. In the Query Editor, you can customize your dataset by filtering, sorting, and summarizing XML columns. Click Edit to open the query editor. Right-click a row to filter the rows. Right-click a column header to perform actions like the following:

   • Change column data types
   • Remove a column
   • Group by columns

   Power BI detects each column's data type from the XML metadata retrieved by the connector.

   Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote XML data. When you click Close and Apply, Power BI executes the data retrieval query.

   Otherwise, click Load to pull the data into Power BI.

How to Create Data Visualizations in Power BI

After pulling the data into Power BI, you can create data visualizations in the Report view by dragging fields from the Fields pane onto the canvas. Follow the steps below to create a pie chart:

1. Select the pie chart icon in the Visualizations pane.
2. Select a dimension in the Fields pane: for example, [ personal.name.first ].
3. Select a measure in the Fields pane: for example, [ personal.name.last ].

👁 A pie chart showing Account Names and Annual Revenue from Salesforce.

You can change sort options by clicking the ellipsis (...) button for the chart. Options to select the sort column and change the sort order are displayed.

You can use both highlighting and filtering to focus on data. Filtering removes unfocused data from visualizations; highlighting dims unfocused data. You can highlight fields by clicking them:

👁 A highlighted account in a pie chart. (Salesforce is shown.)

You can apply filters at the page level, at the report level, or to a single visualization by dragging fields onto the Filters pane. To filter on the field's value, select one of the values that are displayed in the Filters pane.

👁 Accounts and Annual Revenue filtered by Industry. (Salesforce is shown.)

Click Refresh to synchronize your report with any changes to the data.

At this point, you will have a Power BI report built on top of live XML data. Learn more about the CData Power BI Connectors for XML and download a free trial from the CData Power BI Connector for XML page. Let our Support Team know if you have any questions.
