In XML processing, which technology uses a stylesheet as a collection of…

Concept

A transformation stylesheet is declarative: it associates patterns over source-tree nodes with templates that construct the output.

In XSLT, a template rule contains a match pattern and a template body, so the stylesheet operates as a set of such rules.

Application

The stem asks for an XML-processing technology whose stylesheet is organized as templates and template rules. XSL provides this transformation model through XSLT.

Contrast

• XML defines a markup syntax for structuring and labeling data; it is the source or result format rather than the transformation stylesheet language.

• CSS applies selector-and-declaration rules to presentation, but it does not use XSLT-style template rules to transform an XML source tree.

• DHTML is a collective term for HTML, CSS, scripting, and the DOM used to make web pages dynamic; it is not a single stylesheet specification.

• XSL is the stylesheet family for transforming and formatting XML, with XSLT defining the template-rule transformation mechanism.

Cross-check and result

The defining pair of ideas in the stem—templates plus rules that match source nodes—corresponds to the XSLT model within XSL.

Therefore, the required technology is XSL.
