I'm trying to figure out how to programatically access error messages
produced by the Sablotron engine.
It seems that by default if there is a parse or transformation error, a
message (such as: "Error [code:2] [URI:arg:/_stylesheet] [line:45]
XML parser error 7: mismatched tag") goes to stderr.
Is there any way for calling code to get access to these messages (for
instance, to present them to the end-user of an application that uses the
Sablotron library)?
If there is no current functionality to do so, might it be possible to add
another argument to the SablotProcess* functions that points to the error
message (if any) if the return value is non-zero?
For example:
int SablotProcessStrings(char *styleSheetStr,
char *inputStr,
char **resultStr,
char **errorStr) // new argument
So calling code could call SablotProcessStrings() as usual.
If it returns non-zero, instead of retrieving the transformation
output by looking at the data pointed to by resultStr, it could retrieve
the error message by looking at the data pointed to by errorStr.
There would also need to be a new function to allow calling code to free
the memory that was allocated for the error message.
Thank you,
Sam
