XML parsing failed for HTML5 after encrypting

Hello,

"XML parsing failed" error shows when loading vtour in HTML5 mode after xml file is encrypted with Encryption Tool in krpano Protect Tool 1.0.8.15 (build 2012-10-05). In FLASH mode with encrypted xml file vtour works fine! In HTML5 and FLASH mode with non-encrypted xml file vtour also works well!!
Please help, how to resolve this issue?

Kind regards!

No encryption for HTML5.

Thank you for the reply!

Until now, I've thought that's the only way to protect xml for HTML5. So there's no xml protection in HTML5?

Encryption works fine to HTML5, you just need to use the HTML5 compatible type.
Click the right checkbox.

If you mean "Use HTML5/Javascript compatible encryption (xml, swf, js files only)" by the right checkbox it doesn't help in my case also!

These are the results from the "http://schneegans.de/sv/" XML Schema Validator:

XML Schema Validator

Well-formed:YesValid:NoHTTP status code:
HTTP Content Type:

  • No schema was found.
  • Your document lacks a namespace declaration such as '<html xmlns="http://www.w3.org/1999/xhtml">' on the document element.
  • Only well-formedness constraints will be checked, while validity constraints will be ignored.

Now, does anybody know is schema supposed to be found and what is that thing about lacking a namespace declaration on the document element?

!! I've found out that encrypting "tour.xml" file from "...\krpano-1.0.8.15-2012-10-05\examples\virtual-tours\demotour-weingut" also reproduces the same error when loading in HTML5 !!

You can all download "krpano Viewer 1.0.8.15" from "http://www.krpano.com/download/download.php?file=krpano10815" so please check it!

I'm unable to duplicate your results. The encrypted version works perfectly for me.

To find out what you're doing wrong, you'll need to show your steps or provide a link to your project.

My steps were..

open krpano Protect Tool.exe
Click encryption tool tab
Check box Use HTML5...
Add files
navigate to tour.xml for the tour you mentioned.
open tour_html5.html in safari.

Hi!

Great, you gave me a clue! It works only in Safari!!
In the latest versions of Firefox and Google Chrome it does not!
See what I was doing and the error in the Firefox <https://www.dropbox.com/sh/yxd8k0507thj550/rUaajTRlgX>

The html5 part doesn't even work in Firefox, so don't worry about it there.
It's a good note for Klaus anyway because it's a strange error. Also the error will dissappear, if you set the user agent to IPAD for example. Then you get to see the html5 display but fail to render properly.

Dear sachagriffin,

Thank you very much for your help! *thumbsup*

If I was a Mac user, not Windows user, than Safari would be my default Internet browser and I wouldn't even notice this error. Anyway, in my case, HTML5 works fine in Firefox if "tour.xml" file is not encrypted. I also hope that Klaus is now aware about this issue.

Kind regards!

You're absolutely right. I just updated FF to the latest version and html5 works fine but will not decode encrypted xml properly.

Yes - I'm already aware about that problem, there were also some other posts about that.

The problem is a Firefox-limitations - when the content of an xml element is larger than 4096 byte (easy for encrypted xml files where everything is stored inside one xml element), then the Firefox Browser internally splits-up this element into several smaller ones.

The next krpano release already contains an internal workaround for this case.

Best regards,
Klaus
