encoding/xml expose line

[Patrick]

Hello all,

I use the XML package from the standard library (encoding/xml) and I wonder why the line attribute of the decoder is not exposed such as 

func (d *Decoder) InputLine() int {

    return d.line

}

The offset for example is exposed:

func (d *Decoder) InputOffset() int64 {

   return d.offset

}

Is there an obvious reason for that that I am missing? Or more in the line of "not yet implemented"?

Thanks

Don't know what you're trying to do, but the only time I've wanted the line number during decoding is when an error occurs.  Then I retrieve it using xml.SyntaxError, assuming that 'error' is of type *xml.SyntaxError.

I have my own programming language (a bit similar to XSLT) and the XML can be valid but there still might be an error such as an uninitialised variable. I'd like to present feedback to the user on which line the error occurred.

I am thinking about opening an issue on GitHub and providing a (simple) patch.

Patrick,

A similar proposal has just been accepted for encoding/csv:

encoding/csv: add the ability to get the line number of a record #44221
