Bug in Flatten To XML

[Wiebe@CARYA]

Hi,


NI forgot to escape the data when you flatten a picture to XML!


If the picture happens to have e.g. "</" in it's data, the unflatten to XML gives an error.


Very minor bug, but still..


Regards,


Wiebe.




NB. Wouldn't it be better XML if they used a CDATA structure for strings and binary data?

Wiebe,

Could you attach a sample set of files (image and VI) that shows the error?  It would be very helpful when trying to figure out if this is expected behavior or not.  I did want to point out the Escape XML function that will go through and replace special characters for you.  Would this take care of this? 

Hope this helps!

Andy,

1) Stangely enough, the Escape XML.vi doesn't escape "</"!

2) Escape XML.vi takes a string, so you have to convert the picture to string. But when you convert the picture to string, the bug isn't there anymore.

So to work around the problem, you can just convert the picture to string (use flatten to string, casting is (without any reason) disabled...).

Someone who wants to flatten pictures to XML should be experienced enough to figure this out, so I wouldn't put the bug on the priority list. Also, fixing it could cause backwards compatibility problems.

Regards,

Wiebe.

Wiebe,

Thanks for finding and reporting this.  Your feedback certainly helps make LabVIEW a better product.  Thanks again!
