### Parse Metalink Files Programmatically

Source: https://context7.com/cloudfoundry/bosh-io-stemcells-windows-index/llms.txt

Extract metadata from .meta4 files using xmllint or Python's xml.etree.ElementTree.

```bash
# Extract download URL from a meta4 file
xmllint --xpath "//*[local-name()='url']/text()" published/windows-2019/2019.96/aws-xen-hvm-go_agent.meta4

# Extract SHA-256 hash
xmllint --xpath "//*[local-name()='hash'][@type='sha-256']/text()" published/windows-2019/2019.96/aws-xen-hvm-go_agent.meta4

# Extract version number
xmllint --xpath "//*[local-name()='version']/text()" published/windows-2019/2019.96/aws-xen-hvm-go_agent.meta4
```

```python
python3 << 'EOF'
import xml.etree.ElementTree as ET

tree = ET.parse('published/windows-2019/2019.96/aws-xen-hvm-go_agent.meta4')
root = tree.getroot()
ns = {'ml': 'urn:ietf:params:xml:ns:metalink'}

for file_elem in root.findall('ml:file', ns):
    print(f"File: {file_elem.get('name')}")
    print(f"URL: {file_elem.find('ml:url', ns).text}")
    print(f"Version: {file_elem.find('ml:version', ns).text}")
    print(f"Size: {file_elem.find('ml:size', ns).text} bytes")
    for hash_elem in file_elem.findall('ml:hash', ns):
        print(f"{hash_elem.get('type').upper()}: {hash_elem.text}")
