Hi tch_hp,

I'm not going to be able to do full debugging for you, but you might try spitting out something like "XDocument.DOM.documentElement.xml" into a XDocument.UI.Alert();

I don't see why it won't work. Here is the complete script code:

/*
* This file contains functions for data validation and form-level events.
* Because the functions are referenced in the form definition (.xsf) file,
* it is recommended that you do not modify the name of the function,
* or the name and number of arguments.
*
*/

// The following line is created by Microsoft Office InfoPath to define the prefixes
// for all the known namespaces in the main XML data file.
// Any modification to the form files made outside of InfoPath
// will not be automatically updated.
//<namespacesDefinition>
XDocument.DOM.setProperty("SelectionNamespaces", 'xmlns:xs="http://www.w3.org/2001/XMLSchema"');
//</namespacesDefinition>

//=======
// The following function handler is created by Microsoft Office InfoPath.
// Do not modify the name of the function, or the name and number of arguments.
// This function is associated with the following field or group (XPath): /Track_Changes/Overview
// Note: Information in this comment is not updated after the function handler is created.
//=======
function msoxd__Overview::OnAfterChange(eventObj)
{
var xmlOverviewUpdate = XDocument.DOM.documentElement.selectSingleNode("/xs:Overview/xs:OverviewUpdate");
xmlOverviewUpdate.value = "true";

// Write code here to restore the global state.

if (eventObj.IsUndoRedo)
{
// An undo or redo operation has occurred and the DOM is read-only.
return;
}

// A field change has occurred and the DOM is writable. Write code here to respond to the changes.

}

And here is the complete schema code:

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Track_Changes">
<xs:annotation>
<xs:documentation>Comment describing your root element</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:sequence>
<xs:element name="Overview">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="OverviewUpdate" type="xs:boolean" use="optional" default="false"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Something is wrong with the XPath. You should double-check that it's correct and then see if you're hitting a namespace issue.

Ok, here's the code I used:

XDocument.DOM.selectSingleNode("/xs:Overview/xs:OverviewUpdate").text="true";

but I get a runtime error -

"'XDocument.DOM.selectSingleNode(...)' is null or not an object"

????

Hi tch_hp and welcome to the forums!

This should be pretty trivial, try this statement:

thisXDocument.DOM.selectSingleNode( "/my:myFields/my:OverviewUpdate" ).text = "true";

You'll have to update the XPath to match your schema exactly, but this should do the trick.

I am trying to write a script in the OnAfterChange event for a text box that will change the value of a boolean atribute to true; that attribute is linked to a checkbox on the form. The schema string element for the text box is called "Overview" and the boolean attribute on that element is called "OverviewUpdate". Any ideas?
