Perhaps you want to use a different set of tags in Product Advertising API
responses than those that are returned by default. For example, because you want to
display responses on a web page, you want to turn the responses into HTML. You have two
choices: you can receive the default Product Advertising API response and then
transform it into HTML (or another set of XML tags) or you can tell Product Advertising API to do the transformation for you so that the result is ready for you to use.
To make Product Advertising API do the work for you, you just need to reference an
XSL stylesheet in your Product Advertising API request.
Product Advertising API provides an XSLT (Extensible Stylesheet Language
Transformation) service to ensure that even novice developers can produce rich content
without complex parsing or programming. XSL is an XML-based language for transforming
XML tags into HTML or any other set of XML tags. To use the Product Advertising API XSLT service, the request must be in REST, and the XSL style sheet must be
referenced using the Style input parameter.
To transform the response
Include the Style parameter in your request.
The referenced stylesheet must be publicly accessible.
For example, the following ItemSearch request specifies the XSLT
stylesheet http://ecs.amazonaws.com/xsl/aws4/item-search.xsl.
