Variable tags can be used to create dynamic web pages as well as making web pages that are easier to maintain. The tags have one thing in common, they store and retrieve information from different places:

variables

Form variables, as well as variables created with tags like <set> and <cset>. Variables are the backbone of RXML programming.

other

Other variables only exist in output tags, like <sqloutput>. The most common use is to transfer a value available from the output tag to a real variable, by using <set variable=foo other=bar>.

defines

or macros are fully internal to the server. They are mostly used for to save authors typing repetitive blocks of text.

tags

It is possible to define new tags, or to redefine an existing HTML tag.

packages

Packages are ready-to-use defines and tags provided by the administrator of the server.

<set>

<unset>

<cset>

<undefine>
