Advanced Saxon HE/PE/EE XQuery Transformation Options

The XQuery transformation scenario allows you to configure advanced options that are specific for the Saxon HE (Home Edition), PE (Professional Edition), and EE (Enterprise Edition) engines. They are the same options as the values set in the user preferences but they are configured as a specific set of transformation options for each transformation scenario.

The advanced options for Saxon 9.6.0.5 Home Edition (HE), Professional Edition (PE), and Enterprise Edition (EE) are as follows:

• Recoverable errors ("-warnings")- Allows the user to choose how dynamic errors are handled. The following options can be selected:
  • recover silently ("silent") - Continues processing without reporting the error.
  • recover with warnings ("recover") - Issues a warning but continues processing.
  • signal the error and do not attempt recovery ("fatal") - Issues an error and stops processing.
• Strip whitespaces ("-strip") - Can have one of the following values:
  • All ("all") - Strips all whitespace text nodes from source documents before any further processing, regardless of any xml:space attributes in the source document.
  • Ignore ("ignorable") - Strips all ignorable whitespace text nodes from source documents before any further processing, regardless of any xml:space attributes in the source document. Whitespace text nodes are ignorable if they appear in elements defined in the DTD or schema as having element-only content.
  • None ("none") - Strips no whitespace before further processing.
• Optimization level ("-opt") - This option allows optimization to be suppressed in cases where reducing the compiling time is important, where optimization conflicts with debugging, or causes extension functions with side-effects to behave unpredictably.
• Use linked tree model ("-tree:linked") - This option activates the linked tree model.
• Enable XQuery 3.0 support ("-qversion:(1.0|3.0)") - If checked, Saxon runs the XQuery transformation with the XQuery 3.0 support (this option is enabled by default).
• Initializer class - Equivalent to the -init Saxon command-line argument. The value is the name of a user-supplied class that implements the net.sf.saxon.lib.Initializer interface. This initializer is called during the initialization process, and may be used to set any options required on the configuration programmatically. It is particularly useful for tasks such as registering extension functions, collations, or external object models, especially in Saxon-HE where the option cannot be set via a configuration file. Saxon only calls the initializer when running from the command line, but the same code may be invoked to perform initialization when running user application code.
  Important: The advanced Saxon-HE/PE/EE options configured in a transformation scenario override the Saxon-HE/PE/EE options defined globally.

The following advanced options are specific for Saxon 9.6.0.5 Professional Edition (PE) and Enterprise Edition (EE) only:

• Use a configuration file ("-config") - Sets a Saxon 9 configuration file that is used for XQuery transformation and validation
• Allow calls on extension functions ("-ext") - If checked, calls on external functions are allowed. Checking this option is recommended in an environment where untrusted stylesheets may be executed. It also disables user-defined extension elements and the writing of multiple output files, both of which carry similar security risks.

The advanced options that are specific for Saxon 9.6.0.5 Enterprise Edition (EE) are as follows:

• Validation of the source file ("-val") - Requests schema-based validation of the source file and of any files read using the document() or similar functions. It can have the following values:
  • Schema validation ("strict") - This mode requires an XML Schema and enables parsing the source documents with strict schema-validation enabled.
  • Lax schema validation ("lax") - If an XML Schema is provided, this mode enables parsing the source documents with schema-validation enabled but the validation will not fail if, for example, element declarations are not found.
  • Disable schema validation - This specifies that the source documents should be parsed with schema-validation disabled.
• Validation errors in the results tree treated as warnings ("-outval") - Normally, if validation of result documents is requested, a validation error is fatal. Enabling this option causes such validation failures to be treated as warnings.
• Generate bytecode ("--generateByteCode:(on|off)") - If you enable this option, Saxon-EE attempts to generate Java bytecode for evaluation of parts of a query or stylesheet that are amenable to such an action.

• Enable XQuery update ("-update:(on|off)") - This option controls whether or not XQuery update syntax is accepted.
• Backup files updated by XQuery ("-backup:(on|off)") - If checked, backup versions for any XML files updated with XQuery Update are generated. This option is available when the Enable XQuery update option is enabled.
