Well, forgetting about OpenDoPE for the moment, http://webapp.docx4java.org/OnlineDemo/ ... nding.html
says that you can bind a dropDownList or a comboBox to your XML part.http://webapp.docx4java.org/OnlineDemo/ ... tem_1.html
Consider the following combo box structured document tag:
Using xml Syntax Highlighting
<w:listItem w:displayText="Zero" w:value="0"/>
<w:listItem w:displayText="One" w:value="1"/>
Parsed in 0.001 seconds, using GeSHi
The value attribute for the first entry is 0 and the second is 1, therefore, these values will be used to determine the display text if the parent structured document tag is mapped to custom XML data in a custom XML data part.
So that only means you can replace your dropDownList/comboBox in situ with the w:displayText, not with the actual value of the XML element.
So that means the 2013 (i think it was 2013) extensions which let you bind rich text, don't get you any further?
I don't think of this as a "condition" as such, since it is limited by the selection in that one dropDownList/comboBox.
By the way I did write a basic VBA implementation of OpenDoPE evaluation ie evaluating conditions; let me take a look at it again to see whether it matches your interactive use case.
