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