Apache Axiom

Apache Axiom is a high-performance XML object model library that provides an XML Infoset-compliant implementation with support for on-demand building and streaming access. It was originally developed as the core of Apache Axis2 but is designed to function independently. Axiom introduces a "pull-through" model using the StAX API, allowing developers to bypass full tree construction and directly access XML event streams. It also supports efficient binary data handling through XOP and MTOM, making it ideal for SOAP-based and other XML-intensive applications.

Features

• Full XML Infoset-compliant object model
• On-demand tree building with StAX-based pull-through access
• Built-in support for XML Optimized Packaging (XOP) and MTOM
• Convenient SOAP Infoset API layered on top of Axiom
• Two implementations: linked list-based and W3C DOM-compatible
• High-performance architecture optimized for large XML documents

Capabilities

• Efficient parsing and manipulation of XML data
• Streaming access to XML content without full memory loading
