Specific types of template engines Template engine is ordinarily included as a part of a template system or application framework, and may be used also as preprocessor, filter, or template processor. Currently, template processing software is most frequently used in the context of development for the web. XSLT is a template processing model designed by W3C. It is designed primarily for transformations on XML data (into web documents or other output). Programming languages such as Perl, Ruby, C, and Java support template processing either natively, or through add-on libraries and modules. JavaServer Pages (JSP), PHP, and Active Server Pages (ASP with VBScript, JScript or other languages) are examples, themselves, of web template engines. Typical Features Template engines typically include features common to most high-level programming languages, with an emphasis on features for processing plain text. Such features include: A web template example The accompanying illustration depicts a simplified processing model for a typical web template engine. The template engine produces a web page by processing the web template source file along with data from a relational database. The template engine replaces variables with specific values. In the illustration, substitution of $X by the database content (in page 01 "Mother", on page 02 "World").A web template might look like this:
