Stumped, help!: bk.getmetadataxml() + BeautifulSoup
I am working on the attached plug-in (works, but only reports: under construction), to customize the metadata in the opf file.
Trouble is, when pass it to soup, as
Spoiler:
Code:
from sigil_bs4 import BeautifulSoup
from sigil_bs4.builder._lxml import LXMLTreeBuilderForXML # From xmlsouptest
.........
metadata = bk.getmetadataxml()
    ##### Uncomment either for the metada_soup to work
    # print(bk.getmetadataxml()) 
    # print(metadata)
    ############
    metadata_soup = BeautifulSoup(bk.getmetadataxml(), 'lxml') # 'lxml', 'xml'
    print('soup= ',metadata_soup, '\n')

what I get in the plug-in window is (1):
Spoiler:
Code:
Status: success
soup= 
fiction science fiction 52c38ef6-669b-488c-8307-71d9cc6d3ff5 1950-04-15T05:00:00+00:00 Stilson, Charles Billings en Polaris and the Goddess Glorian Distributed Proofreaders Canada 2020-04-06 Stilson, Charles Billings should be list Stilson, Charles Billings should be whole tag old author: dc:creator ['Stilson', ' Charles Billings'] authorSort Charles Billings Stilson authorName [( Charles Billings Stilson, ' Charles Billings Stilson'), ( Charles Billings Stilson, 'file:asStilson, Charles Billings')] Done

but uncommenting either of the commented-out print() instructions, as:
Spoiler:
Code:
metadata = bk.getmetadataxml()
    ##### Uncomment either for the metada_soup to work
    # print(bk.getmetadataxml()) 
    print(metadata)
    ############
    metadata_soup = BeautifulSoup(bk.getmetadataxml(), 'lxml') # 'lxml', 'xml'
    print('soup= ',metadata_soup, '\n')

gives instead (2):

Done

- It drove me batty, to spot *when* the 'type (2)' report, with tags, would become 'type (1)'--not a single tag in sight--while I hadn't done anything that looked significant (comment/uncomment a print() instruction shouldn't be only cosmetic?)
- Please, am I missing something? Some format instruction to be added in situation (1)?
The internal works (navigation & assignments) seem right, but the soup doesn't look adequate for dropping back into the opf file...

Greatly appreciate any help: (stumped)**3!
