Difference between XmlNodelists (XmlNodelist class)

Difference is a member of the XmlNodelist class.

This function 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

%nlis
An XmlNodelist that is set to point to the nodelist that is created.
inNlis
An XmlNodelist.
inNlis2
An XmlNodelist; nodes on this nodelist are removed from inNlis to create the result.

Usage notes

  • Difference only affects the nodes created on nlis; it does not modify the XmlDoc, inNlis, nor inNlis2.
  • The XmlDoc associated with inNlis and nr must be the same.

Example

The following example will create an empty XmlNodelist: 

    %empty = %nlis:Difference(%nlis)

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

Request-Cancellation Errors

  • The XmlDocs associated with inNlis and inNlis2 are not the same.
  • Insufficient free space exists in CCATEMP.

.if 1 = 0 .do

If you want to select nodes in a XmlDoc and remove them from a nodelist, see ?? refid=$xmrmv..

See also ?? refid=$xmplcl.. .do end
