Number of nodes in this nodelist (XmlNodelist class)
Syntax
%number = nodl:Count
Syntax terms
%count | A numeric variable for the number of nodes on XmlNodelist nlis. |
---|---|
nlis | An XmlNodelist expression, specifying the nodelist 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 b1 </a> <a> a2 b2 </a> <a> a3 b3 </a> </top>
