Saxon-HE/PE/EE Preferences

To configure global options for XSLT transformation and validation scenarios that use the Saxon HE/PE/EE engine, open the Preferences dialog box (Options > Preferences) and go to XML > XSLT-FO-XQuery > XSLT > Saxon > Saxon-HE/PE/EE.

Saxon-HE/PE/EE Options

Oxygen XML Developer allows you to configure the following XSLT options for the Saxon 9.7.0.19 Home Edition (HE), Professional Edition (PE), and Enterprise Edition (EE):
Use a configuration file ("-config")
Sets a Saxon 9.7.0.19 configuration file that is executed for XSLT transformation and validation processes.
Version warnings ("-versmsg")
Warns you when the transformation is applied to an XSLT 1.0 stylesheet.
Line numbering ("-l")
Line numbers where errors occur are included in the output messages.
Debugger trace into XPath expressions (applies to debugging sessions)
Instructs the XSLT Debugger to step into XPath expressions.
Expand attributes defaults ("-expand")
Specifies whether or not the attributes defined in the associated DTD or XML Schema are expanded in the output of the transformation you are executing.
DTD validation of the source ("-dtd")
Specifies whether or not the source document will be validated against their associated DTD. You can choose from the following:
  • On - Requests DTD validation of the source file and of any files read using the document() function.
  • Off - (default setting) Suppresses DTD validation.
  • Recover - Performs DTD validation but treats the errors as non-fatal.
    Note: Any external DTD is likely to be read even if not used for validation, since DTDs can contain definitions of entities.
Recoverable errors ("-warnings")
Allows you 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")
Allows you to choose how the strip whitespaces operation is handled. You can choose 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")
Allows you to set the optimization level. It is the value is an integer in the range of 0 (no optimization) to 10 (full optimization). This option allows optimization to be suppressed when reducing the compiling time is important, optimization conflicts with debugging, or optimization causes extension functions with side-effects to behave unpredictably.

Saxon-PE/EE Options

The following options are available for Saxon 9.7.0.19 Professional Edition (PE) and Enterprise Edition (EE) only:
Allow calls on extension functions ("-ext")
If selected, the stylesheet is allowed to call external Java functions. This does not affect calls on integrated extension functions, including Saxon and EXSLT extension functions. This option is useful when loading an untrusted stylesheet (such as from a remote site using http://[URL]). It ensures that the stylesheet cannot call arbitrary Java methods and thus gain privileged access to resources on your machine.
Register Saxon-CE extension functions and instructions
Registers the Saxon-CE extension functions and instructions when compiling a stylesheet using the Saxon 9.7.0.19 processors.
Note: Saxon-CE, being JavaScript-based, was designed to run inside a web browser. This means that you will use Oxygen XML Developer only for developing the Saxon-CE stylesheet, leaving the execution part to a web browser. See more details about executing such a stylesheet on Saxonica's website.
Enable assertions ("-ea")
In XSLT 3.0, you can use the xsl:assert element to make assertions in the form of XPath expressions, causing a dynamic error if the assertion turns out to be false. If this option is selected, XSLT 3.0 xsl:assert instructions are enabled. If it is not selected (default), the assertions are ignored.

Saxon-EE Options

The options available specifically for Saxon 9.7.0.19 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 document() or similar functions. It can have the following values:
  • Schema validation ("strict") - This mode requires an XML Schema and allows for parsing the source documents with strict schema-validation enabled.
  • Lax schema validation ("lax") - If an XML Schema is provided, this mode allows for 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 result tree treated as warnings ("-outval")
Normally, if validation of result documents is requested, a validation error is fatal. Selecting this option causes such validation failures to be treated as warnings.
Write comments for non-fatal validation errors of the result document
The validation messages for non-fatal errors are written (wherever possible) as a comment in the result document itself.
Generate bytecode ("--generateByteCode:(on|off)")
If you select 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. For further details regarding this option, go to http://www.saxonica.com/documentation9.5/index.html#!javadoc.
