Read elements from trusted XML.
Python: Use ElementTree to inspect a small trusted XML document.
import xml.etree.ElementTree as ET
root = ET.fromstring('<items><item id="7">Ada</item></items>')
for item in root.findall("item"):
print(item.attrib["id"], item.text)Expected output EXAMPLE
7 Ada
Details
Save as snippet.py and run python3 snippet.py. Uses the Python standard library. Use ElementTree to inspect a small trusted XML document.
For untrusted XML, use a parser and limits appropriate to its security requirements.

Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
