bea-xf:trim-right

Removes the trailing white space from $string-var.

If the value of $string-var is the empty sequence, the following error is displayed in the mapper:

Error occurred while executing XQuery: Error loading the XQuery or XSLT for this method: Type error in function trim-right invocation: expected type [string@http://www.w3.org/2001/XMLSchema], given type empty 

The empty sequence is a sequence containing zero items (), which is similar to null in SQL.

Remove Trailing Spaces

Invoking trim-right(" abc ") returns the string " abc" as shown in the following example query:

<result>{bea-xf:trim-right("   abc   ")}</result> 

The preceding query, generates the following XML result:

<result>    abc</result> 

Error—Null

Invoking trim-right(()) outputs an error. The string: () is the empty sequence (similar to a SQL null) which is a sequence containing zero items.

For example, the following example query:

<result>{bea-xf:trim-right(())}</result> 

Outputs the following error:

Error occurred while executing XQuery: Error loading the XQuery or XSLT for this method: Type error in function trim-right invocation: expected type [string@http://www.w3.org/2001/XMLSchema], given type empty
