[btOOL] escaping problems

[Guillaume R. <Gui...@in...>]

I'm using Text::BibTeX to convert bibtex database to XML. I faced small
escaping problems I was unable to solve properly.

First, all entries keep internal formating braces.
Such a bibtex entry:
title =3D "Automata-based Parsing in Dynamic Programming for
    {L}inear {I}ndexed {G}rammars"
Result in following title value:
Automata-based Parsing in Dynamic Programming for
{L}inear {I}ndexed {G}rammars

Second, I was unable to convert accentued characters macros, such as \'E
to =C9, even when trying to use macro-related functions, such as
add_macro_text('\\\'E', '=C9') or add_macro_text("\\'E", '=C9')

The only solution I found is an ugly hack to add additional function in
original Text::BibTeX namespace, so as to convert values on the fly:

sub convert {
    $_[0] =3D~ s/{//g;
    $_[0] =3D~ s/}//g;
    $_[0] =3D~ s/\\'E/=C9/g;
    $_[0] =3D~ s/\\'o/=F3/g;
    $_[0] =3D~ s/\\'a/=E1/g;
    return $_[0];
}

package Text::BibTeX::Entry;

sub safe_get {
    my ($self, $field) =3D @_;
    return main::convert($self->get($field));
}

package Text::BibTeX::Name;

sub safe_part {
    my ($self, $field) =3D @_;
    return
        map { main::convert($_) }
        $self->part($field);
}

Is there any other solution ?
