Class SaxonOutputKeys


  • public class SaxonOutputKeys
    extends java.lang.Object
    Provides string constants that can be used to set output properties for a Transformer, or to retrieve output properties from a Transformer or Templates object.

    These keys are private Saxon keys that supplement the standard keys defined in javax.xml.transform.OutputKeys. As well as Saxon extension attributes, the list includes new attributes defined in XSLT 2.0 which are not yet supported in JAXP

    Note that for JAXP compatibility, the names of properties use Clark format, that is {uri}local. However, from 10.0, the values of properties containing QNames, such as cdata-section-elements, use EQName format, that is Q{uri}local.

        public static final java.lang.String RECOGNIZE_BINARY
        recognize-binary = yes|no.

        If set to "yes", and the output is being written using output method "text", Saxon will recognize two processing instructions <?hex XXXX?> and <b64 XXXX?> containing binary data encoded as a hexBinary or base64 string respectively. The corresponding strings will be decoded as characters in the encoding being used for the output file, and will be written out to the output without checking that they represent valid XML strings.

        See Also:
        Constant Field Values
      • REQUIRE_WELL_FORMED

        public static final java.lang.String REQUIRE_WELL_FORMED
        saxon:require-well-formed = yes|no.

        Indicates whether a user-supplied ContentHandler requires the stream of SAX events to be well-formed (that is, to have a single element node and no text nodes as children of the root). The default is "no".

        See Also:

      • SUPPLY_SOURCE_LOCATOR

        public static final java.lang.String SUPPLY_SOURCE_LOCATOR

      • WRAP

        public static final java.lang.String WRAP
        wrap="yes"|"no".

        This property is only available in the XQuery API. The value "yes" indicates that the result sequence produced by the query is to be wrapped, that is, each item in the result is represented as a separate element. This format allows any sequence to be represented as an XML document, including for example sequences consisting of parentless attribute nodes.

        See Also:
        Constant Field Values
      • UNFAILING

        public static final java.lang.String UNFAILING
        Property saxon:unfailing used to indicate that serialization should not fail. This is used when a serialization method such as XML or JSON is invoked from the ADAPTIVE serialization method, and it tailors the error-handling behaviour of the subsidiary output method. There is nothing to stop the property being set directly by the user, though (at least in the XSLT case) the resulting behaviour is non-conformant. The values of the property are yes/no.

                                                     throws XPathException
        Process a serialization property whose value is a list of element names, for example cdata-section-elements
        Parameters:
        value - The value of the property as written
        nsResolver - The namespace resolver to use; may be null if prevalidated is set or if names are supplied in EQName format
        useDefaultNS - True if unprefixed names are to be treated as being in the default namespace
        prevalidated - true if the property has already been validated
        allowStar - true if the pseudo-name "*" is permitted; it will be retained in the output
        errorCode - The error code to return in the event of problems
        Returns:
        The list of element names with lexical QNames replaced by EQName names, starting with a single space
        Throws:
        XPathException - if any error is found in the list of element names, for example, an undeclared namespace prefix
      • isUnstrippedProperty

        public static boolean isUnstrippedProperty​(java.lang.String key)
        Ask whether a particular serialization property is to be considered as string-valued, in which case the value is used exactly as specified without any whitespace stripping.

        The logic here is a little pragmatic.

        For XSLT (xsl:output and xsl:result-document) the properties doctype-system, doctype-public, item-separator, and media-type have string type and whitespace should therefore be retained.

        For values in a parameter document, doctype-system is not whitespace stripped (and is restricted by a pattern); doctype-public is whitespace-stripped; media-type is whitespace-stripped

        For values in an fn:serialize parameter map, doctype-system, doctype-public, encoding, item-separator, media-type, and version are non-stripped strings

        XQuery output declarations follow the rules for parameter documents

        Pragmatically, it makes sense to be consistent. Including whitespace in doctype-system, doctype-public, encoding, version, or media-type is never useful. So we apply whitespace-stripping to all properties other than item-separator.

        Parameters:
        key - the property name, in Clark notation
        Returns:
        true if the property is retained as written without whitespace stripping
      • isXhtmlHtmlVersion5

        public static boolean isXhtmlHtmlVersion5​(java.util.Properties properties)
        Examine the already-validated properties to see whether the html-version property is present with the decimal value 5.; used to decide whether to produce XHTML 5.0 in the XHTML output method.
        Parameters:
        properties - the properties to be examined
        Returns:
        true if the properties include html-version="5.0". The property is a decimal value, so it can also be written, for example, "5" or "+5.00".
      • isHtmlVersion5

        public static boolean isHtmlVersion5​(java.util.Properties properties)
        Examine the already-validated properties to see whether the html-version property is present with the decimal value 5.0, or if absent, the version property is present with the value 5.0. Used to decide whether to produce HTML5 output in the HTML output method.
        Parameters:
        properties - the properties to be examined
        Returns:
        true if the properties include html-version="5.0". The property is a decimal value, so it can also be written, for example, "5" or "+5.00".
