If-tags make it possible to make dynamic pages that show different content based on conditions. Authenticated users can get confidential information and pages can be optimized for all browsers. They also makes it possible to program web application in RXML, without using any programming language.

The if tags are:

<if>

Container tag used to conditionally show its contents.

<else>

Shows the contents if the previous <if> tag didn't, or if preceded by a <false>.

<elseif>

Same as the <if>, but it will only evaluate if the previous <if> tag returned false.

<true>

An internal tag used to set the return value of <if> tags.

<false>

An internal tag used to set the return value of <if> tags.
