Tips for working with XML documents

Tips for working with XML

1. Always specify the encoding

The XML prologue must contain an encoding indication: ``.

2. Use XSD for validation

XML Schema Definition (XSD) allows you to strictly define the valid structure of a document.

3. XPath for navigation

XPath is a powerful query language for extracting data from XML. Learn basic expressions to work efficiently.

4. Escape special characters

Five characters require escaping in XML: `<`, `>`, `&`, `'`, `"`.

5. CDATA for raw data

If the element contains HTML or code, wrap it in `` instead of escaping it.

6. Use attributes for metadata

Data is in elements, metadata (id, type, format) is in attributes.

7. Minimize nesting

Deep nesting makes it difficult to read and increases the file size. Aim for a flat structure.

8. Format before committing

Consistent XML formatting makes diff and code review easier.
