XML Parser Error: What is the matter with this code?

Question

UPDATE:

Hi,

I've narrowed down the problem(s) and it appears to be in this part of the code:

<script type="text/javascript">
oxm_ad = {"website":"cca5e4b8-7ed2-848b-ffea-037efaac851a",
"size":"468x60",
"floor":"0.1",
"beacon":"<div id='beacon_f936906f11' style='position: absolute; left: 0px; top: 0px; visibility: hidden;'><img src='http:\/\/www.mywebsite.com\/openx\/www\/delivery\/lg.php?bannerid=1&amp;campaignid=1&amp;zoneid=4&amp;loc=http%3a%2f%2flocalhost%2fproperty-debug%2fproperty.html&amp;cb=f936906f11&amp;bannerid=-1' width='0' height='0' alt='' style='width: 0px; height: 0px;' \/><\/div>",
"fallback":"<a href='http:\/\/www.mywebsite.com\/openx\/www\/delivery\/ck.php?oaparams=2__bannerid=1__zoneid=4__cb=f936906f11__oadest=http%3a%2f%2fwww.mywebsite.com' target='_blank'><img src='http:\/\/www.mywebsite.com\/openx\/www\/delivery\/ai.php?filename=mybanner.png&amp;contenttype=png' width='468' height='60' alt='' title='' border='0' \/><\/a><div id='beacon_f936906f11' style='position: absolute; left: 0px; top: 0px; visibility: hidden;'><img src='http:\/\/www.mywebsite.com\/openx\/www\/delivery\/lg.php?bannerid=1&amp;campaignid=1&amp;zoneid=4&amp;loc=http%3a%2f%2flocalhost%2fproperty-debug%2fproperty.html&amp;cb=f936906f11' width='0' height='0' alt='' style='width: 0px; height: 0px;' \/><\/div>"};
</script>

Thank you.

Hi,

I'm getting error 1090, an xml parser error. My code is:

   if (!document.max_used) document.max_used = ',';
   document.write ("<scr"+"ipt type='text/javascript' src='"+m3_u);
   document.write ("?zoneid=4");

Does anyone know what the problem might be?

Thank you!

Answer 1

XML is case-sensitive. Try using CDATA instead of cdata.

Answer 2

You have style='width: 0px; height: 0px;' \/>, and \ is not a valid attribute in XML.

The real problem here is that you want the content of the script element (or possibly the entire content of the adXMLReturn element) to be treated as text and you aren't encoding it properly.

If you want something to be treated as text then you need to either:

1. Encode special characters (i.e. <, & and > should be <, & and > respectively) or
2. Mark them as CDATA

Note that you cannot nest CDATA sections, so if you want the entire content to be treated as text, you will need to either change the first script or use method one.

If you build your XML using an XML tool instead of by hand or using templates, then it will take care of all that for you.

On the subject of the first script, it is quite broken at the moment. Unless you really want to comment it out remove the <!-- and -->. You might want to see Comments and CDATA for more on that subject.

Answer 3

Hi,

Okay, I've got it figured out. The problem was in the script block that I mentioned. I had to rip out all of the blackslashes.

Thank you David and Michael for their input.

The corrected bit looks like:

<script type="text/javascript">
oxm_ad = {"website":"cca5e4b8-7ed2-848b-ffea-037efaac851a",
"size":"468x60",
"floor":"0.1",
"beacon":"<div id='beacon_f936906f11' style='position: absolute; left: 0px; top: 0px; visibility: hidden;'><img src='http://www.mywebsite.com/openx/www/delivery/lg.php?bannerid=1&amp;amp;campaignid=1&amp;amp;zoneid=4&amp;amp;loc=http%3a%2f%2flocalhost%2fproperty-debug%2fproperty.html&amp;amp;cb=f936906f11&amp;amp;bannerid=-1' width='0' height='0' alt='' style='width: 0px; height: 0px;' /></div>",
"fallback":"<a href='http://www.mywebsite.com/openx/www/delivery/ck.php?oaparams=2__bannerid=1__zoneid=4__cb=f936906f11__oadest=http%3a%2f%2fwww.mywebsite.com' target='_blank'><img src='http://www.mywebsite.com/openx/www/delivery/ai.php?filename=mybanner.png&amp;amp;contenttype=png' width='468' height='60' alt='' title='' border='0' /></a><div id='beacon_f936906f11' style='position: absolute; left: 0px; top: 0px; visibility: hidden;'><img src='http://www.mywebsite.com/openx/www/delivery/lg.php?bannerid=1&amp;amp;campaignid=1&amp;amp;zoneid=4&amp;amp;loc=http%3a%2f%2flocalhost%2fproperty-debug%2fproperty.html&amp;amp;cb=f936906f11' width='0' height='0' alt='' style='width: 0px; height: 0px;' /></div>"};
