如何提取XML美汤的信息？

Question

I have a list of XML beautifulsoap tag elements as:

[
 <Entry>
    <EffectiveDate>
    <DateFormattedForTHForm>07/01/2022</DateFormattedForTHForm>
    </EffectiveDate>
    <ExpirationDate>
    <DateFormattedForTHForm>07/01/2023</DateFormattedForTHForm>
    </ExpirationDate>
    <FormDescription>Notification Of Settlement</FormDescription>
    <FormNumber>WC 99 06 04</FormNumber>
 </Entry>,
 
 <Entry>
 <AccountContactRole>
 <AccountContact>
    <Contact>
    <DisplayName>Mallesham Yamulla</DisplayName>
    <FEINOrSSN>123-45-6789</FEINOrSSN>
    <formsMaskedSSN_and_NoMaskFEIN>**-***-8834</formsMaskedSSN_and_NoMaskFEIN>
    <PrimaryAddress>
    <AddressLine1>A</AddressLine1>
    <AddressLine123>B</AddressLine123>
    <CityStateZip>ENID, OK 73703</CityStateZip>
    <Country>IND</Country>
    <AddressLine2 xsi:nil="true"/>
    <AddressLine3 xsi:nil="true"/>
    </PrimaryAddress>
    </Contact>
    </AccountContact>
    </AccountContactRole>
 </Entry>
 
 ]

Here I would like to loop through the list of entry xml elements, get a tag name and its contained information's, if any of tag is empty and its information is also empty it should be ignored.

From first entry the below tag information is required to be extracted as they hold on information.

[<DateFormattedForTHForm>07/01/2022</DateFormattedForTHForm>,
<DateFormattedForTHForm>07/01/2023</DateFormattedForTHForm>,
<FormDescription>Notification Of Settlement</FormDescription>,
<FormNumber>WC 99 06 04</FormNumber>]

From second entry:

    <DisplayName>Mallesham Yamulla</DisplayName>
    <FEINOrSSN>123-45-6789</FEINOrSSN>
    <formsMaskedSSN_and_NoMaskFEIN>**-***-6789</formsMaskedSSN_and_NoMaskFEIN>
    <PrimaryAddress>
    <AddressLine1>A</AddressLine1>
    <AddressLine123>B</AddressLine123>
    <CityStateZip>ENID, OK 73703</CityStateZip>
    <Country>IND</Country>

(With "list of XML beautifulsoup tag elements" in variable xTagList ,) you could try something like this

bsParser = 'html.parser' # 'xml' # 
# xTagList = [BeautifulSoup(str(x), bsParser) for x in xTagList] # should fix some formatting
wCont_xstrs = ['\n'.join([
    str(d) for d in x.descendants if hasattr(d, 'find_all') 
    and not d.find_all() and d.get_text().strip()
]) for x in xTagList]

to get html/xml string.

with bsParser = 'xml' , wCont_xstrs looks like

[
<DateFormattedForTHForm>07/01/2022</DateFormattedForTHForm>
<DateFormattedForTHForm>07/01/2023</DateFormattedForTHForm>
<FormDescription>Notification Of Settlement</FormDescription>
<FormNumber>WC 99 06 04</FormNumber>
,
<DisplayName>Mallesham Yamulla</DisplayName>
<FEINOrSSN>123-45-6789</FEINOrSSN>
<formsMaskedSSN_and_NoMaskFEIN>**-***-8834</formsMaskedSSN_and_NoMaskFEIN>
<AddressLine1>A</AddressLine1>
<AddressLine123>B</AddressLine123>
<CityStateZip>ENID, OK 73703</CityStateZip>
<Country>IND</Country>
]

[btw, if your xml had namespaces (as well formed xmls usually do), they would be lost after using xml parser. Using html parser will preserve namespaces, but there will be another issue as you will see below.]

---

with bsParser = 'html.parser' (and probably any other parser other than xml ), wCont_xstrs looks like

[
<dateformattedforthform>07/01/2022</dateformattedforthform>
<dateformattedforthform>07/01/2023</dateformattedforthform>
<formdescription>Notification Of Settlement</formdescription>
<formnumber>WC 99 06 04</formnumber>
,
<displayname>Mallesham Yamulla</displayname>
<feinorssn>123-45-6789</feinorssn>
<formsmaskedssn_and_nomaskfein>**-***-8834</formsmaskedssn_and_nomaskfein>
<addressline1>A</addressline1>
<addressline123>B</addressline123>
<citystatezip>ENID, OK 73703</citystatezip>
<country>IND</country>
]

(notice how capitalization has been lost from tag names)

If you want a list bs4 objects, you can do something like

wCont_xtags = [BeautifulSoup(x, bsParser) for x in wCont_xstrs]

UNLESS you're using bsParser = 'xml' , because then you need to wrap them in some tag first like

wCont_xtags = [BeautifulSoup(f'<Entry>{x}</Entry>', bsParser).Entry for x in wCont_xstrs]
