XMLResolver is used to resolve external XML resources, such as entities, document type definitions (DTDs), or schemas. It is also used to process include and import elements found in Extensible StyleSheet Language (XSL) style sheets or XML Schema definition language (XSD) schemas.

XMLParser is a software that reads an XML document, identifies all the XML tags and passes the data to the application.
