Getting Extra Tags when Loading Presentation in Aspose.Slides for Java 15.5

Hi,

I am in process of migarting Aspose Slides version from ASPOSE SLIDES JAVA 15.3.0 to ASPOSE SLIDES JAVA 15.5.0. I ran in to an issue while working with some presentations.

I just loaded a presentation which originally does not have any tags and then save it back in pptx format. I am seeing around ten tag.xml files when I unzipped saved powerpoint presentation.

The content of one of the tag.xml is given below:

<p:tagLst
xmlns:p=“http://schemas.openxmlformats.org/presentationml/2006/main ”>

<p:tag name="AS_UNIQUEID " val="2 " />

</p:tagLst>

Other tag.xml also have tag with same name “AS_UNIQUEID” mapped to different tag values.

We were not seeing these extra tags in Version ASPOSE SLIDES JAVA 15.3.0.

I am just curious to know what these extra tags mean and why are they needed?

I am attaching both the presentations for your reference.

The code we used is given below:

void savePresentation(){

Presentation ppt=new Presentation(“AnimationsWithSlideContent.pptx”);

ppt.save(“AnimationsWithSlideContent_Saved.pptx”,SaveFormat.Pptx);

}

Thanks

Hi,


Is there any update on this issue?

With Aspose.Slides JAVA 15.6.0, I am seeing this issue got worsen. Now I am seeing these extra tags with so many PowerPoint Presentations we are using for out testcases. These tags are being referred in various xml and rels files of PowerPoint like slide.xml, slideLayout.xml etc


With Aspose.Slides JAVA 15.5.1, we observed this issue with one presentation which contained Animations. Does this issue also occurs with other types of features or objects?

Please tell us which PowerPoint features we need to avoid so that we do not see these extra tags.

Please resolve this issue as soon as possible as we eagerly want to migrate to Aspose.Slides JAVA 15.6.0 version.

Thanks
Manisha

Hi,


I observed a specific behavior with Aspose Slides Java 15.6.0 for PowerPoint containing animations.

I tried a very simple code given below with may PowerPoint presentation containing animations:

public void testPresentationWithAnimations(){

Presentation ppt=new Presentation(“AnimationsWithSlideContent.pptx”);
ppt.save(“AnimationsWithSlideContent_1.pptx”);

Presentation ppt=new Presentation(“AnimationsWithSlideContent_1.pptx”);
ppt.save(“AnimationsWithSlideContent_2.pptx”);


Presentation ppt=new Presentation(“AnimationsWithSlideContent_2.pptx”);
ppt.save(“AnimationsWithSlideContent_3.pptx”);


Presentation ppt=new Presentation(“AnimationsWithSlideContent_3.pptx”);
ppt.save(“AnimationsWithSlideContent_4.pptx”);

Presentation ppt=new Presentation(“AnimationsWithSlideContent_4.pptx”);
ppt.save(“AnimationsWithSlideContent_5.pptx”);

}

Number of tags present in following PowerPoint Presentations:

1. AnimationsWithSlideContent.pptx: 1
2. AnimationsWithSlideContent_1.pptx: 10
3. AnimationsWithSlideContent_2.pptx: 94
4. AnimationsWithSlideContent_3.pptx: 94
5. AnimationsWithSlideContent_4.pptx: 94
6. AnimationsWithSlideContent_5.pptx: 94

I observed that extra tags being generated only for first two save and after that tags count remains constant.This behavior is not only limited to this PowerPoint. I noticed same behavior with other PowerPoint presentations which consists of animations.

Attaching sample presentations for your reference.

Hoping this information may help you in resolving this issue.

Thanks
Manisha
