Out of the box, A2J is compatible with HotDocs for document assembly purposes. However, it is possible to develop XSL transforms that will translate the data exported in A2J Guided Interviews® answer file (.anx) into an alternative XML format. One such XSLT has been written thus far for LSXML, which is used by Pika case management systems.
Two instructional articles on writing XSLTs for A2J Guided Interviews are made available below for your reference. Each article was written by John Mayer, Executive Director of CALI, and include a download (.zip) including examples XSLTs. The first of the articles addresses XSLTs for Pika and also includes instructions for setting up A2J Author locally on your own server. The second of the articles address XSLTs to HTML.
