XML

XML is a hierarchical, tag-based markup language that stores structured data in human-readable text:

<product id="123">
  <title>Noise-Cancelling Headphones</title>
  <price currency="USD">199.99</price>
</product>

Why XML still matters

• Industry feeds: Many ecommerce, travel, and finance APIs still publish XML.
• Strict schema validation: XSD / DTD enforce data integrity.
• Rich metadata: Supports attributes, namespaces, and mixed content.

Collecting XML with Proxied

1. Fetch feeds through Proxied 4G/5G rotating proxies to bypass IP-based quotas and regional blocks.
2. Validate against XSD to ensure clean ingestion.
3. Transform to JSON or relational tables downstream.
