Bumping ppt4jx version to 8.1.0.2

[andreyi]

Hi.
I have updated pptx4j to 8.1.0.2:

<dependency>
<groupId>com.plutext</groupId>
<artifactId>docx4j-Enterprise-MergePptx</artifactId>
<version>8.1.0.2</version>
</dependency>

But there is a problem with CTExtension class. In plutext 6.1.0.0 the "any" property of that class was instance of Node class. But in 8.1.0.2 "any" is JAXBElement. Is there a way to create a Node object from the JAXBElement, because our logic related with pptxs use Nodes, Nodelist in many places?

Thanks.

Hi Andrey

There is a CTExtension class in a few different packages, so could you please give the full package name?

I thought you might be referring to org.pptx4j.pml.CTExtension, but it hasn't changed recently:-

In docx4j 8.1.3, we have at https://github.com/plutext/docx4j/blob/ ... n.java#L65

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "CT_Extension", propOrder = {
    "any"
})
public class CTExtension implements Child
{

    @XmlAnyElement(lax = true)
    protected Object any;

This was the same in docx4j 6.1.2: https://github.com/plutext/docx4j/blob/ ... nsion.java and the ObjectFactory methods for creating them haven't changed either.

Also, which JAXB implementation are you using? Did you change it recently?

You should be able to create a Node object from a JAXBElement by marshalling it (XmlUtils.marshaltoW3CDomDocument) but I'd like to understand better the issue you are experiencing.

cheers .. Jason

On further examination, the reason for the change in behaviour is that in Version 8.1.0, [MS-PPTX] and [MS-ODRAWXML] content models were updated with latest schemas.

This introduced org.pptx4j.com.microsoft.schemas.office.powerpoint.x2010.main.CTRandomId; see
https://github.com/plutext/docx4j/blob/ ... domId.java

(That's what the JAXBElement contains)

To confirm this, remove package org.pptx4j.com.microsoft.schemas.office.powerpoint.x2010.main, and remove that package from jcPML. The relevant element then unmarshalls as a DOM element.

                if (o instanceof javax.xml.bind.JAXBElement) {
                        Object o2 = XmlUtils.unwrap(o);
                        System.out.println("containing " + o2.getClass().getName());
                       
                        Document d = XmlUtils.marshaltoW3CDomDocument(o, Context.jcPML);
                        System.out.println(d.getDocumentElement().getLocalName());
                }

(You can also force use of a DOM element by using "lax = false" in CTExtension, but the code has never been that way)

Hi, Jason.
Thank, you for the suggestion. It help me.
