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.
