Try using xmltype.createxml(xml).

As in,

select extract(xmltype.createxml(xml), '//fax').getStringVal() from mytab;

It worked for me.

If you want to improve or manipulate even further.

Try something like this.

Select *
from xmltable(xmlnamespaces('some-name-space' as "ns", 
                                  'another-name-space' as "ns1",
                           ), 
                    '/ns/ns1/foo/bar'
                    passing xmltype.createxml(xml) 
                    columns id varchar2(10) path '//ns//ns1/id',
                            idboss varchar2(500) path '//ns0//ns1/idboss',
                            etc....

                    ) nice_xml_table
