Difference (XmlNodelist function)

Difference between XmlNodelists (XmlNodelist class)

Difference creates an XmlNodelist that is the difference of (that is, it removes nodes from) one XmlNodelist and another.

Syntax

%diffNodl = nodl:Difference( removeNodl)

Syntax terms

%diffNodl	An XmlNodelist that is set to point to the nodelist that is created.
nodl	An XmlNodelist.
removeNodl	An XmlNodelist; nodes on this nodelist are removed from nodl to create the result.

Usage notes

• Difference only affects the nodes created on %diffNodl; it does not modify the XmlDoc, nodl, nor removeNodl.
• The XmlDoc associated with nodl and removeNodl must be the same.

Examples

1. The following example will create an empty XmlNodelist:

   %empty = %nlis:Difference(%nlis)

2. Another example that makes use of the Difference method is in the "Examples" section in SelectNodes
