Re: [xml] strange behaviour of SAX characters callback

["Vladimir F." <faidenv logica com>]

Thanks Daniel,

But how can I determine that sequence of "character" callbacks
relates to the same element? Is it right to assume that all
"character" callbacks between "enterElemen" and "exitElement"
callbacks relate to the same element? Is there another solution?
