Issue - 103 - Standardizing $varName syntax for XPath to refer to a BPEL variable

Status: open
Date added: 9 Mar 2004
Submitter: Alex Yiu
Date submitted: 08 March 2004

Right now, there are three BPWS functions defined in BPEL can be called in an XPath Query / Expression.

bpws:getVariableProperty ('variableName', 'propertyName')
bpws:getVariableData ('variableName', 'partName'?, 'locationPath'?)
For refering to a variable data, if data is of an XSD complex type or XSD simple type (not WSDL 1.1 type), we want to add one more way to refer to a variable on top of getVariableData() Function Call? That is using "$varName" syntax.

Currently, we have:
"bpws:getVariableData(orderDetails) > 100"
The additional way will look like:
"$orderDetails > 100"
Note that:
