About:
Expat is a stream-oriented XML 1.0 parser library written in C. It provides a robust and high-performance foundation for parsing XML data incrementally, making it ideal for network protocols and large file processing. Its lightweight design and portability have made it a core component in countless software projects.

Key Features:

Stream-oriented parsing for low memory usage
High performance and highly configurable
Written in C for maximum portability
Supports multiple character encodings

Use Cases:

Parsing XML configuration files in C/C++ applications
Handling XML-based network protocols like SOAP
Processing large XML datasets without loading entire file into memory

Alternatives:

libxml2 – More feature-rich (includes XPath, schema validation) but larger and more complex than Expat.
