XML and XSLT

The Recognia API returns XML by default. Recognia's XML returns have a standard XML header to provide information to the developer about the API, such as version information, and the API call, such as warning messages. A sample XML return from the fictional "query" command is provided below.

The API supports applying XSL Transforms (XSLT) to the results of an API call in order to transform the XML into an alternate format such as HTML or Text. For example, it may desirable to return the following results as an HTML table so that it can be directly embedded in a web page. To apply a transform the XSLT must have be registered with the API. Then the XSLT identifier can be specified in the API call (as a parameter) to transform the XML into the alternate format. Recognia's clients may develop their own XSLT style-sheets or may use or modify sample XSLT style-sheets developed by Recognia.
