RE: XML-SAX parsing issue

[Justin Taylor <JUSTIN@xxxxxxxxxxxxx>]

IE thinks that the XML is properly formed.



I'll try the 
chars = %Subst( charsUCS2: 1:stringLen );

I'm currently doing the chars = charsUCS2 assignment and then using (stringLen/2) to parse out chars.

Although I can't see why it would screw things up Justin, you should never simply code chars = charsUCS2;

You must delimit the string by stringLen - there will potentially be a bunch of garbage in the back end of charsUCS2 which could cause a burp in the character conversion.

So it should always be:

> chars = %Subst( charsUCS2: 1:stringLen );

And you should only be performing that assignment if stringLen is > 0;

Can't see from your code but assumedly you are only doing this assignment when the event code says that you have UCS2 data?

Would also suggest (for other reasons) that you change the definition of chars to be varying length - then you won't need to be trimming it or whatever as you go along.

It appears that the XML events are working properly.  I eye-balled the XML and I can't see anything wrong with it.  I don't even know where to go with this.
