Example XPath Expressions

The following are example expressions for message, element and complex schema type variables.

Element type variable:

Example: $AStatus/e:statusDescription

Selects the statusDescription child node of AStatus element

Message type variable:

Example: $StatusVariable.StatusPart2/e:statusDescription

Selects the statusDescription child node of the StatusPart2 part of StatusVariable

Schema complex type variable:

Example: $Results/e:AuctionResult[2]/@AuctionID

Selects the AuctionID attribute of the second AuctionResult child node

Expression statement: itemsShipped = itemsShipped + itemsCount:

$itemsShipped + $shipnotice.props/itemsCount

The following expression converts a variable and part to a string:

string($input.parameters)

Referencing a child node by localname only

This can be useful when a schema has an xsd:any element in it, such as:

<xs:any minOccurs="0" maxOccurs="unbounded" namespace="##other" processContents="lax"/>

The Expression Builder doesn't show the structure in the variable tree view. To use the element, the namespace prefix can be ignored as in this example:

$creditInformation/*[local-name()="previousLoanApplicationAttempts"][1]/*[local-name()="applicationDate"]

Selects the date of the first previous loan application, if information about previous loan applications is supplied as additional content for the creditInformation message.
