I'm getting an exception when using Paragraphs.AddFromHtml()

Aspose.Slides Product Family

Hello,

I’m using Slides 7.5.1.0, and having three problems, mostly with regard to AddFromHtml():

  1. When importing some simple HTML, calling AddFromHtml() doesn’t result in any exceptions, but the resulting TextFrame doesn’t display the HTML content.
  2. With a more complex chunk of HTML, AddFromHtml() returns an exception – index out of range
  3. When opening the final PPTX file in PowerPoint 2013, I’m getting a “PowerPoint can attempt to repair this file” http://screencast.com/t/m9hxFH5nn

Here’s a complete solution to demonstrate the issues. Thanks for taking a look.

Thanks for inquiring Aspose.Slides.

I have worked with the sample code shared by you and have been able to observe the two issues specified. An issue with ID SLIDESNET-34453 has been created in our issue tracking system to further investigate and resolve the issue. For the issue related to first HTML text, i suggest you to please try using following html text for the time being.

string sampleHTML = “Hello”;

We are sorry for your inconvenience,

Hi,

I am using Slides 8.0.0.0 and having the following problem with regard to AddFromHtml()

1. When importing simple HTML , calling AddFromHtml() works fine , but using Numbered bullets or other complex formatting, I am getting the "Index out of range" exception when saving the PPTX.

Please find the sample HTML text I have used below,

1.test1

2.test2

3.test3

which is saved as below in the db

  1. test1
  2. test2
  3. test3

When trying to render on screen using AddFromHtml() , I am getting the above error.

I am using the latest version of Aspose Slide (8.0.0.0) which shows to have fixed the bug but still facing this issue. Please advice.

Regards,

Vaishnavi K.

Hi Mudassir,

In addition to the earlier raised issue, I was unable to render the following HTML tags in the generated PPTX as well

1. Strike -

test

2. Subscript -

test

3.Superscript -

test

The above tags did not reflect any change in the PPTX and only the word "test" was displayed when the PPTX was generated

Another issue was when copying text from MS Word , the text is saved with some additional HTML tags in the DB. When I tried to use AddFromHtml() on the text , I got "EOF in processing directive error"

Eg : I have copied the word "test" from MS word which saved as the following HTML string

<FONT color=#ff0000> <P style="MARGIN: 0in 0in 10pt" class=MsoNormal><FONT color=#000000><FONT face=Calibri>test<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></FONT></FONT></P></FONT>

On using AddFromHtml() on this string , I got the above mentioned error.

Kindly request your help and support in the mentioned issues.

Regards,

Vaishnavi K.
