|Attribute or Element||Description||Value|
|condition attribute||Required. This expression is evaluated before each pass through the activities in the <while> element. Once false, it stops execution of the <while> element.||An expression that evaluates to the integer value 1 (if true) or 0 (if false). This expression must use the scripting language specified by the containing <process> element.|
|name, disabled, xpos, ypos, xend, yend attributes||See “Common Attributes and Elements.”|

The <while> element defines a sequence of activities that are repeatedly executed as long as a logical expression evaluates to the integer value 1 (true). The expression is re-evaluated before each loop through the sequence.
<while condition="0"> //...do various things... <if condition="somecondition"> <true> <break/> </true> </if> //...do various other things... </while>
