How to align the Select result

Question

I’m drawing up a report, where I take a person’s name, and what days they work. I was able to make that select, but I need it to stay that way:

[JOÃO - SEG/QUART]
[MARIA - TERÇ/QUINT]
[JOSÉ - SEG/TER/QUART]

I used (xmlagg), but it’s not working.

select DISTINCT 
    Substr(Obter_nome_medico(ag.CD_PESSOA_FISICA,'N'), 1, 100) nm_medico,
    rtrim(xmlagg(xmlelement(e,substr(obter_valor_dominio(35,at.ie_dia_semana),1,1000),';').extract('//text()')),';')
from TABELA1 a, TABELA2 ag, TABELA3 at
where Substr(Obter_nome_medico(ag.CD_PESSOA_FISICA, 'N'), 1, 100) is not null 
and a.cd_agenda = ag.CD_AGENDA 
and ag.cd_agenda = at.cd_agenda 
group by Substr(Obter_nome_medico(ag.CD_PESSOA_FISICA,'N'), 1, 100);
