Nonlibxml

Nonlibxml refers to XML processing solutions that do not depend on the libxml library family, particularly libxml2. The term is descriptive rather than a formal project name, and it may be used to describe libraries, wrappers, or in-house parsers chosen to avoid libxml2 in certain environments or workflows.

Rationale. Projects may avoid libxml2 for licensing constraints, binary size, portability, or security concerns. Some ecosystems require lighter dependencies, prefer permissive licenses, or must operate in constrained environments such as embedded systems. In addition, some organizations replace a C library with a native implementation or a parser tailored to specific XML usage patterns.

Alternatives. A range of non-libxml options exists. Expat is a widely used independent XML parser. TinyXML-2 and PugiXML are small, C++ libraries aimed at simplicity. Many languages provide built-in XML support (for example, Java's and Python's standard libraries) that do not rely on libxml2. Some projects implement their own parsers to meet specialized needs.

Impact and considerations. Choosing a non-libxml solution often involves weighing API compatibility, feature support (DOM vs SAX, namespaces, validation), performance, and maintenance burden. Without libxml2, teams may need to adapt existing code, data workflows, and tools to operate with alternative APIs and data models.
