Error handling when parsing strings

[John Dunn]

I'm having problems getting useful error messages parsing an XML document from a string. I've tried both TiXmlDocument.Parse and istringstring >> TiXmlDocument.

If I pass in invalid XML data I get the following results

Parse()
  doc.Error() = true
  doc.ErrorDesc = Error document empty.
  doc.ErrorId = 13

>> TiXmlDocument
  doc.Error() = true
  doc.ErrorDesc = null
  doc.ErrorId = 13

Is there any way to get useful error messages out of the library?

Do you mean it works with "Parse()" but not ">>" ?

I've gone back and attempted to reproduce the case where the stream operator was not giving my a valid ErrorDesc() but unfortunately I didn't save it.

I think some of my confusion was due to the ErrorDesc itself. I was parsing a string that looks like "aaa<test></test>" and did not expect an error message of "Error document empty." - I was hoping for something a little more descriptive. For example, IE gives the following error -

  Invalid at the top level of the document.

and Firefox gives-

  XML Parsing Error: not well-formed

both of which I find more helpful than the TinyXML error.
