ARB: API Error Code: E00003 An error occurred while parsing the XML request.

Does this error (API Error Code: E00003  An error occurred while parsing the XML request.) simply mean there was an error parsing the XML and there's nothing I can do about it? About 10-20% of our submissions fail, and when they get this message, there is seemingly nothing wrong with the XML at all. The XML in fact passes standard XML validation.

Any other explanations for why we would get this error?

There should be some detail error message about why it fail parsing. It could be missing data(blank), field length too long, XML node out of sequence. Have you check it with authorize.net schema?

Thats all the error it gives me. Where can I go to have the XML tested with more detail?

Download the schema at https://api.authorize.net/xml/v1/schema/AnetApiSchema.xsd 

And use whatever tool you have or try it online.

And I found a web site where you can test the xml. Just make sure you masked you loginID and Key.
