The following examples demonstrate techniques
for entering mapping expressions in the Edit pane.
- If the target element is derived from a source element, drag the source
element or elements onto the Edit pane; for example:
$source/Properties/MessageSet
- Use arithmetic expressions, such as:
$source/Properties/Priority + 1
- Use mapping, Xpath or ESQL function names. Content Assist ()
provides a list of available functions.
For example:
esql:upper($source/Properties/ReplyIdentifier)
- You can perform casting in the Edit pane; for example:
xs:string($source/Properties/CodedCharSetId)
You cannot enter an expression for a simple element if one of its ancestors
also has a mapping. For example, you cannot map Properties from source to
target, then set a value of Properties/MessageFormat.
