Reference

Confluence XML exposes its component in charge of parsing and analyzing confluence exports. It can be used independently by using component org.xwiki.contrib.confluence.filter.input.ConfluenceXMLPackage:

@Inject
private Provider<ConfluenceXMLPackage> confluencePackageProvider;

public void analyze()
{
  // Create a new instance of ConfluenceXMLPackage component
  ConfluenceXMLPackage confluencePackage = this.confluencePackageProvider.get();

  // Parse the packaged located on the file system (but support any org.xwiki.filter.input.InputSource which lead to a zip content or a directory)
  confluencePackage.read(new DefaultFileInputSource(new File("path/to/the/confluencepackage.xml.zip")));

  // Call the various getters of ConfluenceXMLPackage
}
