How to use Application.DisplayXMLSourcePane in the xlwings API way

The DisplayXMLSourcePane member of the Application object in Excel is a property that controls the visibility of the XML Source task pane. This pane is used when working with XML maps in Excel, allowing users to view and manage XML elements mapped to cells or ranges in a workbook. It is particularly useful for developers and advanced users who handle XML data integration, enabling them to see the structure of XML data and its mappings directly within the Excel interface. In xlwings, this property can be accessed and manipulated to programmatically show or hide the XML Source pane, enhancing automation in workflows involving XML data processing.

In terms of syntax, the DisplayXMLSourcePane property is accessed through the Application object in xlwings. The xlwings API provides a Pythonic way to interact with Excel’s object model. The property is a boolean value, where True indicates that the XML Source pane is visible, and False indicates it is hidden. The xlwings call format is straightforward: you reference the Application object and set or get the DisplayXMLSourcePane property. For example, to retrieve the current state, you use app.api.DisplayXMLSourcePane, and to change it, you assign a boolean value like app.api.DisplayXMLSourcePane = True. Note that in xlwings, the api attribute is used to access the underlying Excel object model properties and methods directly, ensuring compatibility with Excel’s native functionality.

Here are some code examples demonstrating the use of DisplayXMLSourcePane with xlwings. First, ensure you have xlwings installed and an Excel instance running. You can use the following snippets in a Python script or interactive environment. In the first example, we check if the XML Source pane is currently visible and print its status:

import xlwings as xw

# Connect to the active Excel instance
app = xw.apps.active

# Get the current state of the DisplayXMLSourcePane property
is_visible = app.api.DisplayXMLSourcePane
print(f"The XML Source pane is visible: {is_visible}")

To show the XML Source pane, set the property to True:

# Show the XML Source pane
app.api.DisplayXMLSourcePane = True
print("XML Source pane is now visible.")

To hide it, set the property to False:

# Hide the XML Source pane
app.api.DisplayXMLSourcePane = False
print("XML Source pane is now hidden.")

You can also toggle the visibility based on its current state. This is useful in automation scripts where you might need to ensure the pane is visible before performing XML-related operations:

# Toggle the visibility of the XML Source pane
current_state = app.api.DisplayXMLSourcePane
app.api.DisplayXMLSourcePane = not current_state
print(f"Toggled XML Source pane visibility to: {not current_state}")
