PROBLEM with parent TAG in VBS

Now I need it to rename the XML with CNPJ followed by the date, but the problem is that the CNPJ tag is not unique, there are multiple CNPJs in the xml ... I need only the CNPJ inside the tag, I managed to make it work in a way here, but there are some XML that I get that the order changes, so as it takes the first CNPJ tag that it has, sometimes it gets the CNPJ from another tag other than the. can you help me? Here are the codes:
