Difference (XmlNodelist function)

Difference between XmlNodelists (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.
