rsb:else

The rsb:else keyword is used to execute an alternative block of code when a test like rsb:exists or rsb:match fails. It can also be used to execute an alternate block of code within an rsb:call when the call fails to produce any output items.

Unlike other languages, rsb:script requires the rsb:else statement to be within the scope of the test it belongs to. See the examples.

Parameters:

• This keyword does not have any parameters.

Control Attributes:

• This keyword does not have any control attributes.

Examples:

<rsb:notnull attr="rss:title">
    <rsb:push/>
    <rsb:else>
        <rsb:set attr="rss:title" value="Item"/>
        <rsb:push/>
    </rsb:else>
</rsb:notnull>

<rsb:info title="FileListElse" description="Feed of empty dir">
    <input name="path" desc="Empty dir" default="empty" />
</rsb:info>
<rsb:call op="fileListDir" output="out">
    <rsb:push title="[rss:title | def('untitled item')]">
        [out.*] 
    </rsb:push>
    <rsb:else>
        <rsb:push title="No files">
            Directory '[path]' is empty. 
        </rsb:push>
    </rsb:else>
</rsb:call>
