XML Parsing Error: not well-formed

One column information gives me this error. how can i fix that

XML Parsing Error: not well-formed

You should well form your xml

i’m not using XML .
is that can be because of the text format? it occurs only in one column where i store text data in Unicode (UTF-8) format.
please,help me to resolve this.

It can be
a) special chars, such as <>&
b) incorrect encoding of data, the xml header contains info about used encoding , and if you declare data as utf-8 ( default ) and provides data in different encoding - error can occur.

yes. there a special character in our events. but we need that.
Our xml is starting like below:

<?xml version='1.0' encoding='iso-8859-1' ?>

our data is “gesê”. this is giving problem

if we just copy the xml and open in browser then its not giving any problem. But if we open in firefox it is giving us error that “XML Parsing Error: not well-formed”

I believe that is because of the Response Header is using utf-8. I am not sure how to change it. see attached file.

Please let us know how we can let this special character to allow in firefox and IE. It is working fine in google chrome.

It still maybe the problem with locale. While xml states that data is in iso-8859-1, actual data can be UTF encoded.

Can you attach the problematic XML file ( please save file and attach it to the post, do not copy its content, as encoding information will be lost )
