Hello,

I fixed the probleme by adding :

    /**

* Aspose.Words calls this method to get a value for every data field.

*/

public boolean getValue(String fieldName, Object[] fieldValue) throws Exception

{
if (StringUtils.isBlank(fieldName)) {
return false;
}
        // Attempt to retrieve the child node matching the field name by using XPath.

        Node value = (Node)retrieveExpression(fieldName).evaluate(mCurrentNode, XPathConstants.NODE);

// We also look for the field name in attributes of the element node.

        Element nodeAsElement = (Element)mCurrentNode;

    <span class="code-keyword" style="color: rgb(0, 0, 145); background-color: inherit;">if</span> (value != <span class="code-keyword" style="color: rgb(0, 0, 145); background-color: inherit;">null</span>)
    {
        <span class="code-comment" style="color: rgb(128, 128, 128); background-color: inherit;">// Field exists in the data source as a child node, pass the value and <span class="code-keyword" style="color: rgb(0, 0, 145); background-color: inherit;">return</span> <span class="code-keyword" style="color: rgb(0, 0, 145); background-color: inherit;">true</span>.



            // This merges the data into the document.

            fieldValue[0] = value.getTextContent();

return true;

}

else if (nodeAsElement.hasAttribute(fieldName))

{

// Field exists in the data source as an attribute of the current node, 
            // pass the value and return true.

            // This merges the data into the document.

            fieldValue[0] = nodeAsElement.getAttribute(fieldName);

return true;

}

else

{

// Field does not exist in the data source, return false.

            // No value will be merged for this field and it is left over in 
            // the document.

            return false;

}
}

Hope that will not cause a regression :smiley:
