XSD dosyası Python ile nasıl ayrıştırılır
Oct 08 2020
İçerideki 3 ismi almak için aşağıdaki XSD'yi nasıl ayrıştırabilirim <xsd:complexType name="Register-Type" abstract="true">
"Ölçüler", "açıklama" ve "notlar" adlarını almak ve her birini csv'de bir sütuna koymak istiyorum (başka bilgi yok, sadece bu 3 isim şimdilik başlık olarak gösteriliyor).
Lxml kullanmaya çalışıyorum ama istediğim özel complexType etiketine nasıl gireceğimi bilmiyorum.
XSD dosyası aşağıdadır:

BeautifulSoup'u etiketlediğinizden beri, bunu şu şekilde yapabilirsiniz:
import csv
from bs4 import BeautifulSoup
soup = BeautifulSoup(your_xml, "xml")
tag_names = soup.find("xsd:complexType", {"name": "Register-Type"})
with open('data.csv', 'w') as f:
headers = [tag['name'] for tag in tag_names.find_all("xsd:element")]
writer = csv.DictWriter(f, fieldnames=headers)
writer.writeheader()
data.csv :
