Which Open XML Parser for C is Right for My Project?

Finding the Optimal Open XML Parser for C

When in need of an XML parser for C , it's tempting to consider writing your own. However, there are several open-source options that offer distinct advantages.

RapidXML: The Speed Demon

RapidXML is a highly efficient XML DOM parser tailored for performance. Its lightning-fast parsing speeds and minimal memory requirements make it ideal for embedded environments and applications where resources are scarce. With its headers-only implementation and permissive licensing, integrating RapidXML is a breeze.

Limitations of RapidXML

Despite its speed, RapidXML has some limitations:

• Ignores DOCTYPE declarations
• No support for XML namespaces
• Does not check for character validity
• Interface does not conform to DOM specifications

CodeSynthesis XSD: XML Data Binding

CodeSynthesis XSD takes a different approach by generating C classes based on an XML Schema specification. This enables data binding, allowing seamless parsing and serialization. CodeSynthesis XSD offers two mappings:

• C /Tree: Traditional in-memory data structure
• C /Parser: SAX-like mapping for stream-oriented processing

Benefits of CodeSynthesis XSD

• Handles large XML documents that cannot fit in memory
• Supports stream-oriented processing
• Leverages existing in-memory representations

Conclusion

Both RapidXML and CodeSynthesis XSD offer unique strengths for parsing XML in C . RapidXML excels in performance and efficiency, while CodeSynthesis XSD provides data binding capabilities and handles large documents effectively. The best choice depends on the specific requirements and limitations of your project.
