Functions

In order to convert values into certain formats or to use selection functions, eBiss offers a variety of mapping functions.

Note:: eBiss is based on. NET technology and therefore supports XPath 1.0, i. e. all functions which are possible in XPath 1.0 can be used in the mapping selections..
See XQuery 1.0 and XPath 1.0 Functions and Operators¹⁾

Examples of XPATH functions frequently used in the mapping context:

• count()is a function with the help of which you can use e. g. trigger rules Rulsets:

  count(GroupByExSorted(//Groups,"CustomItem[@Key='EK_Abteilung']/@Value")) > 1

• concat() is used for concatenating strings:

  concat(@DocNumber,'-DokumentnummerPostfix')

Note: As a rule, data element names (instead of the character strings specified in quotation marks) can always be used in functions where this is not explicitly specified.

• General example:

  FunctionName(@DataElement)
