How to print the custom error message on DB errors?

[eluser]Unknown[/eluser]
Hi,

I'm using CI 1.7.3 and developing a program which only respond to the client as XML. Users access this service through their client program on the mobile device.

CI prints a pretty formed HTML error message to the client on DB connection or query errors. However, it is useless to me and I want to print a custom XML(represent an error) message without CI default error message.

Is there a way to do this like an error callback handler?

Thank you.

Thank you for your reply. However, CI shows its own error message immediately when an error condition is occurred in the active record DB. So, I cannot prevent CI default error message through show_error() function.
