This function extracts arbitrary values from BPEL variables.

When only the first argument is present, the function extracts the value of the variable, which must be defined using an XML schema simple type or element. Otherwise, the return value of this function is a node set containing the single node representing either an entire part of a message type (if the second argument is present and the third argument is absent) or the result of the selection based on the locationPath (if both optional arguments are present).

Signature:

bpws:getVariableData ('variableName', 'partName'?, 'locationPath'?)

Arguments:

• variableName: The source variable for the data.

• partName: The part to select from the variable (optional).

• locationPath: Provides an absolute location path (with / meaning the root of the document fragment representing the entire part) to identify the root of a subtree within the document fragment representing the part (optional).

Property IDs:

• namespace-uri: http://schemas.xmlsoap.org/ws/2003/03/business-process/
