API Parsing Error

I sometimes get this error when I try to call the searches api.

XML Parsing Error: not well-formed
Location: http://api.getclicky.com/api/stats/4?site_id=xx&sitekey=xxx&type=searches&date=2011-10-17&limit=all
Line Number 918, Column 23:

I can't seem to find a reason why. I put in the day before or after and it works. I'm get the error for about 25 dates. I could hard code it but then I don't know if it happens again.

It will come up with a list of search phrases and count but then it seems to not display all of them.

Probably a invalid character, which tend to happen with searhces most often. We try out damndest to strip all of those out before displaying them either on the site or in the API but some still manage to slip through. If you look at line 918 character 23, it's probably a character your computer can't display properly.

Oh I see it. Thanks.

Is there anything we can do on our side like add the character?

I just came across the same issue and I solved it by opening the original download from API and finding where the invalid character is. Then wrap the whole string using CDATA between the XML tags. I was using SimpleXML (in PHP) and that fixed the problem.

Also, this is for the getclicky devs, would it be possible to have CDATA tags by default where appropriate, or does that create other problems?
