Appendixes > Category XML Format > Introduction

Introduction
There are two ways to use an XML file to create a category structure within IDOL:
*
Use the IDOL Categorizer. To import a hierarchy from an XML file, execute the CategoryImportFromXML action command, as in this example:
http://IDOLhost:port/action=CategoryImportFromXML&ImportFilename=MyCategory.xml&BuildNow=true
For information on importing category information using Categorizer, see Categorization.
*
Use the Autonomy Collaborative Classifier. To import a hierarchy from an XML file, you must use the Taxonomy module.
For information on importing category information using Autonomy Collaborative Classifier, see the Autonomy Collaborative Classifier User Guide.
