[Xerte-dev] Re: sanpit example of non standard chars

[Smith, John]

Yes I suspect it is the PHP function that creates the XML object in play/preview and most likely export too that doesn't like that character

There is a check in save.php that removes either char(0) or char(1) [can't remember off the top of my head which] because we had an example a yaer or so ago where that character made its way into the XML and then caused problems. I thing there must be a whole load of characters that are possible to enter but that PHP XML doesn't like...

Subject: [Xerte-dev] sanpit example of non standard chars

Hi all
thought I should share this example of what was a non playing if not corrupted LO from the sandpit…

The helpdesk had a report from a user that his LO wouldn't export and now wouldn't play.
I checked the export first and sure enough it wouldn't export and then I verified that it wouldn't play either even though all looked ok in the editor.
So then I looked at the xml expecting it to be corrupt like we've had with other examples previously but in this case both preview.xml and data.xml were still complete. However I noticed two oddities shown in the following screenshots:

1. US instead of fingerprint line 121
[cid:image005.jpg at 01CF9C5B.CD149970]

2. what should have neen an apostrophe line 116
[cid:image006.jpg at 01CF9C5B.CD149970]
I've attached a copy of the xml so hope this gets through.

Questions I asked along with answers:


1. Did you copy and paste text in from Word or another external source?

I did copy, but from Word and PowerPoint into Notepad so I could remove the formatting, then pasted into the LO.



2. Did you re-import these LO's at any point?

No



3. Are you ok with the dev team looking at a copy of the xml from your LO to try to identify the exact cause and future prevention?

Yes



I wonder if this would have ended up with a completely broken LO rather than just one that wouldn't play or export and I should add that after removing the UN directly from the xml and adding an apostrophe via the editor the LO plays and exports again.
