Number of nodes in this nodelist (XmlNodelist class)
Count is a member of the 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
<b>b1</b>
</a>
<a>
a2
<b>b2</b>
</a>
<a>
a3
<b>b3</b>
</a>
</top>
