Properties (original) (raw)

| | If you have created a DOM document builder or a SAX parser using the JAXP interfaces, the following instructions tell you how to set properties on document builders and SAX parsers created from the JAXP interfaces. The DocumentBuilderFactory interface contains a setAttribute(String,Object) method which may provide a means to set properties on the underlying parser. When using Xerces, you can set the value of a property with this method. For example: The SAXParser interface contains asetProperty(String,Object) method which can be used to set properties on the underlying implementation of XMLReader. You can also retrieve the underlying XMLReader from the SAXParser allowing you to set and query properties on it directly. For example: | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| | Desc: Get the string of characters associated with the current event. If the parser recognizes and supports this property but is not currently parsing text, it should return null. Type: java.lang.String Access: read-only Note: This property is currently not supported because the contents of the XML string returned by this property is not well defined. Desc: The XML Schema Recommendation explicitly states that the inclusion of schemaLocation/noNamespaceSchemaLocation attributes is only a hint; it does not mandate that these attributes must be used to locate schemas. Similar situation happens to element in schema documents. This property allows the user to specify a list of schemas to use. If the targetNamespace of a schema (specified using this property) matches the targetNamespace of a schema occurring in the instance document in schemaLocation attribute, or if the targetNamespace matches the namespace attribute of element, the schema specified by the user using this property will be used (i.e., the schemaLocation attribute in the instance document or on the element will be effectively ignored).Type: java.lang.String Access: read-write Note: The syntax is the same as for schemaLocation attributes in instance documents: e.g, "http://www.example.com file_name.xsd". The user can specify more than one XML Schema in the list. Desc: This property allows the user to specify an XML Schema with no namespace.Type: java.lang.String Access: read-write Note: The syntax is a same as for the noNamespaceSchemaLocation attribute that may occur in an instance document: e.g."file_name.xsd". The user may specify only one XML Schema. For more information see the documentation for the http://apache.org/xml/properties/schema/external-schemaLocation property. Desc: A QName or XSElementDeclaration object representing the top-level element declaration used when validating the root element of a document or document fragment (also known as the validation root). If the value of this property is non-null the validation root will be validated against the specified element declaration regardless of the actual name of the root element in the instance document. If the value is a QName and a element declaration cannot be found an error will be reported.Type: javax.xml.namespace.QName or org.apache.xerces.xs.XSElementDeclaration Access: read-write Since: Xerces-J 2.10.0 Note: If the 'root-type-definition' property has been set this property takes precedence if its value is non-null.Note: If the value specified is an XSElementDeclaration it must be an object obtained from Xerces and must also be an object which is known to the schema validator, for example one which would be returned from an XMLGrammarPool. If these constraints are not met a ClassCastException may be thrown or processing of substitution groups, xsi:type and wildcards may fail to locate otherwise available schema components.See: http://apache.org/xml/properties/validation/schema/root-type-definition Desc: A QName or XSTypeDefinition object representing the top-level type definition used when validating the root element of a document or document fragment (also known as the validation root). If the value of this property is non-null and the 'root-element-declaration' property is not set the validation root will not be validated against any element declaration. If the value is a QName and a type definition cannot be found an error will be reported.Type: javax.xml.namespace.QName or org.apache.xerces.xs.XSTypeDefinition Access: read-write Since: Xerces-J 2.8.0 Note: If the 'root-element-declaration' property has been set this property is ignored.Note: Prior to Xerces-J 2.10.0 setting the value of this property to an XSTypeDefinition was not supported.Note: If the value specified is an XSTypeDefinition it must be an object obtained from Xerces and must also be an object which is known to the schema validator, for example one which would be returned from an XMLGrammarPool. If these constraints are not met a ClassCastException may be thrown or processing of substitution groups, xsi:type and wildcards may fail to locate otherwise available schema components.See: http://apache.org/xml/properties/validation/schema/root-element-declaration Desc: The size of the input buffer in the readers. This determines how many bytes to read for each chunk.Type: java.lang.Integer Access: read-write Since: Xerces-J 2.1.0 Note: Some tests indicate that a bigger buffer size can improve the parsing performance for relatively large files. The default buffer size in Xerces is 2K. This would give a good performance for small documents (less than 10K). For documents larger than 10K, specifying the buffer size to 4K or 8K will significantly improve the performance. But it's not recommended to set it to a value larger than 16K. For really tiny documents (1K, for example), you can also set it to a value less than 2K, to get the best performance.Note: There are some conditions where the size of the parser's internal buffers may be increased beyond the size specified for the input buffer. This would happen in places where the text in the document cannot be split, for instance if the document contains a name which is longer than the input buffer. Desc: The locale to use for reporting errors and warnings. When the value of this property is null the platform default returned from java.util.Locale.getDefault() will be used.Type: java.util.Locale Access: read-write Since: Xerces-J 2.10.0 Note: If no messages are available for the specified locale the platform default will be used. If the platform default is not English and no messages are available for this locale then messages will be reported in English. Desc: It is possible to create XML documents whose processing could result in the use of all system resources. This property enables Xerces to detect such documents, and abort their processing.Type: org.apache.xerces.util.SecurityManager Access: read-write Since: Xerces-J 2.3.0 Note: The org.apache.xerces.util.SecurityManager class contains a number of methods that allow applications to tailor Xerces's tolerance of document constructs that could result in the heavy consumption of system resources (see the javadoc of this class for details). Default values that should be appropriate for many environments are provided when the class is instantiated. Xerces will not behave in a strictly spec-compliant way when this property is set. By default, this property is not set; Xerces's behaviour is therefore strictly spec-compliant by default. | |

| | Desc: The current DOM element node while parsing. Type: org.w3c.dom.Element Access: read-only Note: This property is useful for determining the location with a DOM document when an error occurs. Desc: The fully qualified name of the class implementing the org.w3c.dom.Document interface. The implementation used must have a zero argument constructor. Type: java.lang.String Default: "org.apache.xerces.dom.DocumentImpl" Access: read-write Note: When the document class name is set to a value other than the name of the default document factory, the deferred node expansion feature does not work. | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |

| | Desc: Set the handler for DTD declarations. Type: org.xml.sax.ext.DeclHandler Access: read-write Desc: Set the handler for lexical parsing events. Type: org.xml.sax.ext.LexicalHandler Access: read-write Desc: The DOM node currently being visited, if SAX is being used as a DOM iterator. If the parser recognizes and supports this property but is not currently visiting a DOM node, it should return null. Type: org.w3c.dom.Node Access: (parsing) read-only; (not parsing) read-write;Note: This property is only for SAX parser implementations used as DOM tree walkers. Currently, Xerces does not have this functionality. Desc: A literal string describing the actual XML version of the document, such as "1.0" or "1.1".Type: java.lang.String Access: read-only Since: Xerces-J 2.7.0 Note: This property may only be examined during a parse after the startDocument callback has been completed. | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
