Xerces-C++

Top Pro

Additional libraries and applications

Xerces has many applications and libraries that give additional functionality to the parser. XQilla, for example, allows for XQuery and XPath implementation. See More

Top Con

Overkill for simple needs

If a website only uses a small number of XML, that can easily be handled manually, Xerces-C++ may be considered overkill. All the validation and compliance may not be necessary. See More

Top Pro

Validation support

Allows the validation of XML corresponding to the DTD or schema rules linked. See More

Top Pro

Full Unicode support

This allows all characters to be used and read/written in the DOM tree. See More

Top Pro

DOM/SAX compliant

Xerces-C++ comes packaged with the API documentation for SAX and DOM. These are two of the most highly used programming interfaces with XML. Implementation of SAX 1.0/2.0 specification. Implementation of DOM 1.0, 2.0 (Core, Traversal and Range), and 3.0 (Core, Load and Save) specification. See More

pugixml

Top Pro

Full Unicode support

This allows all characters to be used and read/written in the DOM tree. See More

Top Con

Non-validating

The parser will not check the validation rules in the DTD or schema. Only syntax will be checked. See More

Top Pro

XPath support

XPath 1.0 implementation for complex data-driven tree queries. XPath allows for navigation by selecting nodes from the XML. See More

RapidXML

Top Pro

Header-only implementation

This allows for a very simple integration process of the parser into your code. Only the .hpp file would need to be included into the library. See More

Top Con

Not W3C compliant

Ignoring DOCTYPE declarations causes RapidXML to not be a W3C compliant parser. Though it can still successfully parse and produce complete trees of all valid XML files. See More

Top Pro

Very fast parsing speed

"... parsing speed is about 50-100x faster than Xerces DOM, 30-60x faster than TinyXml, 3-12x faster than pugxml, and about 5% - 30% faster than pugixml" See More

Top Pro

Allows modification of the DOM tree

The DOM tree that is created from the parser is fully modifiable. Nodes and attributes can be added/removed, and their contents changed. See More
