XPath
XML Path Language
A query language for selecting nodes from an XML document using path expressions.
Техническая деталь
XPath follows a strict tree structure where every element must be properly nested and closed. Namespaces (xmlns) prevent element name collisions when combining vocabularies. DTD (Document Type Definition) and XML Schema (XSD) provide validation against a defined structure. SAX and DOM are the two primary parsing approaches: SAX is event-driven and memory-efficient for large documents; DOM loads the entire tree into memory for random access.
Пример
```javascript // XPath example const input = 'sample data'; const result = process(input); console.log(result); ```
