# XDocument Object

XDocuments XDocument

Represents the underlying XML document of a Microsoft Office InfoPath 2003 form.

## Remarks

The XDocument object is a key object in the InfoPath object model that provides properties, methods, and events that can be used to programmatically interact with and manipulate the source XML data of a form.

Note The XDocument object is embedded in the InfoPath script engine. While the XDocument object can be accessed using the XDocuments collection, in most cases you will access it directly, without going through the collection.

## Using the XDocument object

The source XML data of a form takes the form of an XML Document Object Model (DOM), which is accessed through the DOM property of the XDocument object. The XDocument object also provides a number of properties that can be used to get information about the form and its underlying XML document. For example, the following code checks to see whether data in the form has been changed by using the IsDirty property:

    if (XDocument.IsDirty)
       XDocument.UI.Alert("Form has been changed.");
    else
       XDocument.UI.Alert("Form has not been changed.");

In addition to information about the form and its underlying XML document, the XDocument object provides a number of methods that can be used on the form, such as printing, saving, and submitting. It also provides a number of events that can be used to respond to various actions that occur at the form level, such as loading of a form, switching views, or a merge operation.

## Accessing the XDocument object

The XDocument object can be accessed in a variety places within the InfoPath object model. The following table summarizes the locations where the XDocument object is available.
