Count (XmlNodelist function)

Number of nodes in this nodelist (XmlNodelist class)

Count returns the number of nodes in an XmlNodelist.

Syntax

%number = nodl:Count

Syntax terms

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

Example

1. 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>
