The global parameters of the XQuery file used in a transformation scenario can be configured by using the Parameters button in the XQuery tab.
The resulting dialog box includes a table that displays all the parameters of the current XQuery file, along with their descriptions and current values. You can also add, edit, and remove parameters, and use the Filter text box to search for a specific term in the entire parameters collection. Note that edited parameters are displayed with their name in bold.
If the XPath column is selected, the parameter value is evaluated as an XPath expression before starting the XQuery transformation.
Example:
doc('test.xml')//entry
//person[@atr='val']- The doc function solves the argument relative to the XQuery file location. You
can use full paths or editor
variables (such as ${cfdu} [current file directory]) to
specify other locations:
doc('${cfdu}/test.xml')//* - Only XPath functions are allowed.
Below the table, the following actions are available for managing the parameters:
- New
- Opens the Add Parameter dialog box that allows you to add a new
parameter to the list. An editor variable can be inserted in the text box using the
Insert Editor Variables button. If the Evaluate as
XPath option is selected, the parameter will be evaluated as an XPath
expression. - Edit
- Opens the Edit Parameter dialog box that allows you to edit the
selected parameter. An editor variable can be inserted in the text box using the Insert Editor
Variables button. If the Evaluate as XPath option
is selected, the parameter will be evaluated as an XPath expression.
- Unset
- Resets the selected parameter to its default value. Available only for edited parameters with set values.
- Delete
- Removes the selected parameter from the list. It is available only for new parameters that have been added to the list.
- The default value of the parameter selected in the table.
- A description of the parameter, if available.
- The system ID of the stylesheet that declares it.
