This can be called up again at another point in the mapping document. In some cases it is necessary to store a value temporarily, e.g. if the value is changed by a calculating function, but the original value is still required elsewhere. The use of variables can significantly improve the performance of a mapping.variablen index text/html 2024-02-20T08:15:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://pranke.com/hilfe/doku.php?id=en:transformation:mappings:variablen:xvar&rev=1708413318&do=diff XVar XVar accelerates access to variables, which is noticeable in multiple calls. For example, if the selection is called frequently in a RuleSet. XVar can be used in the selection and replaces e. g. $var with XVar ('var'). Reason: An XPath selection with a variable must be translated each time XPath accesses the variable to determine its content. If you use XVar, the selection is only translated once and calls the function XVar for further accesses.
