Select

The Select parameter type denotes the XPath from which the input is considered. If the operation is of the type Select, then the Source column must contain a single XPath.

Available in both Business Process Model and Case model.

Note: When the value is left empty, the Case model results in a validation failure during design time. For the same scenario, a Business Process Model provides a warning message in design time and ignores the assignment during run time.

Select Multiple

The Select Multiple parameter type denotes the multiple XPath expressions from which the input must be considered.

Available in Business Process Model only. Not available in Case model.

Note: To achieve the required functionality, use the Expression source type and provide the relevant XPath.

Fixed Value

In the parameter type Fixed Value, the value in the Source column is considered as a literal value.

Available in both Business Process Model and Case model.

Note: When the '<!CDATA[concat]]>' type of value is considered in a Business Process Model, the net result of such content evaluation results only in 'concact'. The same in a Case model results in '<!CDATA[concat]]>'.

Expression

In the parameter type Expression, the result of expression evaluation is considered as the source value for assignment. If the '-' (minus) operator is used in the expression, then it must be delimited from operands using a space. Right-click the source field to select all the possible expression constructs. The functions that are used in the expression are executed by the XPath engine at run time. Refer to Creating an XPath Expression for information on the XPath expressions.

Available in both Business Process Model and Case model.

Note: When the value is left empty, the Case model results in a validation failure during design time. For the same scenario, a Business Process Model provides a warning message in design time and ignores the assignment during run time.

Children

The Select parameter type denotes the XPath from which the input is considered. If the operation is of the type Children, then all the sub-elements are assigned to the target element. For example, all the tuple elements containing all orders can be assigned to the source element with the parameter type Children.

Available in Business Process Model only. Not available in Case model.

Note: To achieve the required functionality, use the Expression source type and provide the relevant XPath. For example, if the children of the element Employees must be selected, then use emp:Employees/*.

First Child

If the operation is of the type First Child, then only the first sub-element is assigned to the target element. For example, the first tuple element containing the first order can be assigned to the source element with the parameter type First Child.

Available in Business Process Model only. Not available in Case model.

Note: To achieve the required functionality, use the Expression source type and provide the relevant XPath. For example, if the first child of the element Employees must be selected, then use emp:Employees/*[1].

Last Child

If the operation is of the type Last Child, only the last sub-element is assigned to the target element. For example, the last tuple element containing the last order can be assigned to the source element with the parameter type Last Child.

Available in Business Process Model only. Not available in Case model.

Note: To achieve the required functionality, use the Expression source type and provide the relevant XPath. For example, if the last child of the element Employees must be selected, then use emp:Employees/*[last()].

XML Structure

In the XML Structure parameter type, the complete XML structure must be specified in the source column. For example,

<tuple>
    <new>
        <Orders>
            <OrderID>90</OrderID>
        </Orders>
    </new>
</tuple>

Available in both Business Process Model and Case model.

Note: From this latest version of Process Platform, a Case model evaluates XML input, and provides a validation error if the XML input provided is invalid.

Select with Target NS

Same as Select above. If this option is selected, the namespace of the target element is considered.

Select Multiple with Target NS

Same as Select Multiple above. If this option is selected, the namespace of the target elements are considered.

Children with Target NS

Same as Children above. If this option is selected, the namespace of the target element is considered.

First Child with Target NS

Same as First Child above. If this option is selected, the namespace of the target element is considered.

Last Child with Target NS

Same as Last Child above. If this option is selected, the namespace of the target element is considered.

XML Structure with Target NS

Same as XML Structure above. If this option is selected, the namespace of the target element is considered.
