我是 python 和 XML 的新手。我需要從 XML 檔案中洗掉 UserName 和他所有相應的 FeatureId。我嘗試使用 xml.etree.ElementTree 但無法洗掉 FeatureIds。任何幫助將不勝感激。
示例 XML

例如，我想洗掉 UserName raj 和他從 0 到 6 的所有 FeatureId。提前致謝。
uj5u.com熱心網友回復：
您可以使用beautifulsoup. 檔案
- 首先選擇
<UserName>with 文本（在本例中為 Raj。）。 - 找到它的父級，即
<FeatureEntitlementDetail>使用.findParent()方法。 - 現在洗掉
<FeatureEntitlementDetail>將洗掉用戶名 Raj 的整個樹。你可以使用.decompose()
這是完整的代碼。
import requests
from bs4 import BeautifulSoup
s = """<YOUR XML GOES HERE>"""
soup = BeautifulSoup(s, 'xml')
u = soup.find('UserName', text='[email protected]')
fed = u.findParent()
fed.decompose()
print(soup.prettify())
您可以看到沒有<UserName>Raj 并且<FeatureIds>通過列印soup.
