Syntax

%number = nodl:Count

Syntax terms

%number A numeric variable for the number of nodes in XmlNodelist nodl.
nodl An XmlNodelist expression, specifying the XmlNodelist to count.

Example

In the following example, the Count method is used to limit a For loop which selectively adds nodes to the document:

begin %doc is object xmlDoc %doc = new %doc:loadXml('<top> <a>a1</a> <a>a2</a> <a>a3</a> </top>') %nl1 is object xmlNodelist %n1 is object xmlNode %n2 is object xmlNode %j is float %nl1 = %doc:selectNodes('/top/a') for %j from 1 to %nl1:count %n1 = %nl1:item(%j) %n2 = %n1:addElement('b', 'b' With %j) end for call %d1:print end

The example results follow:

<top> <a> a1 <b>b1</b> </a> <a> a2 <<b>b2</b> </a> <a> a3 <b>b3</b> </a> </top>
