      extended by net.sf.saxon.dom.DocumentBuilderImpl

public class DocumentBuilderImpl
extends DocumentBuilder

This class implements the JAXP DocumentBuilder interface, allowing a Saxon TinyTree to be constructed using standard JAXP parsing interfaces. The returned DOM document node is a wrapper over the Saxon TinyTree structure. Note that although this wrapper implements the DOM interfaces, it is read-only, and all attempts to update it will throw an exception. No schema or DTD validation is carried out on the document.

DocumentBuilderImpl

public DocumentBuilderImpl()
Method Detail

setConfiguration

public void setConfiguration(Configuration config)
Set the Saxon Configuration to be used by the document builder. This non-JAXP method must be called if the resulting document is to be used within a Saxon query or transformation. If no Configuration is supplied, Saxon creates a Configuration on the first call to the parse(org.xml.sax.InputSource) method, and subsequent calls reuse the same Configuration.

As an alternative to calling this method, a Configuration can be supplied by calling setAttribute(FeatureKeys.CONFIGURATION, config) on the DocumentBuilderFactory object, where config can be obtained by calling getAttribute(FeatureKeys.CONFIGURATION) on the TransformerFactory.

Since:
Saxon 8.8

getConfiguration

public Configuration getConfiguration()
Get the Saxon Configuration to be used by the document builder. This is a non-JAXP method.

Returns:
the Configuration previously supplied to setConfiguration(net.sf.saxon.Configuration), or the Configuration created automatically by Saxon on the first call to the parse(org.xml.sax.InputSource) method, or a newly constructed Configuration if no Configuration has been supplied and the parse(org.xml.sax.InputSource) method has not been called.
Since:
Saxon 8.8

isNamespaceAware

public boolean isNamespaceAware()
Indicates whether or not this document builder is configured to understand namespaces.

Specified by:
isNamespaceAware in class DocumentBuilder
Returns:
true if this document builder is configured to understand namespaces. This implementation always returns true.

setValidating

public void setValidating(boolean state)
Determine whether the document builder should perform DTD validation

Parameters:
state - set to true to request DTD validation

isValidating

public boolean isValidating()
Indicates whether or not this document builder is configured to validate XML documents against a DTD.

Specified by:
isValidating in class DocumentBuilder
Returns:
true if this parser is configured to validate XML documents against a DTD; false otherwise.

newDocument

public Document newDocument()
Create a new Document Node.

Specified by:
newDocument in class DocumentBuilder
Throws:
UnsupportedOperationException - (always). The only way to build a document using this DocumentBuilder implementation is by using the parse() method.

parse

public Document parse(InputSource in)
               throws SAXException
Deprecated. since 9.3. The DOM created by this class is a DOM wrapper around (typically) a Saxon Tiny Tree. There is little point in constructing such an object. If the tree is primarily for use by Saxon XSLT and XQuery, it is better to construct a Tiny Tree directly and omit the DOM wrapper; if it is primarily for other DOM applications, it is better to construct a fully- functional DOM using (for example) Apache Xerces.

Parse the content of the given input source as an XML document and return a new DOM Document object.

Note: for this document to be usable as part of a Saxon query or transformation, the document should be built within the Configuration in which that query or transformation is running. This can be achieved using the non-JAXP setConfiguration(net.sf.saxon.Configuration) method.

Specified by:
parse in class DocumentBuilder
Parameters:
in - InputSource containing the content to be parsed. Note that if an EntityResolver or ErrorHandler has been supplied, then the XMLReader contained in this InputSource will be modified to register this EntityResolver or ErrorHandler, replacing any that was previously registered.
Returns:
A new DOM Document object.
Throws:
SAXException - If any parse errors occur.

parse

public Document parse(File f)
               throws SAXException,
                      IOException
Parse the content of the given file as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the File is null null.

This implementation differs from the parent implementation by using a correct algorithm for filename-to-uri conversion.

Overrides:
parse in class DocumentBuilder
Parameters:
f - The file containing the XML to parse.
Returns:
A new DOM Document object.
Throws:
IOException - If any IO errors occur.
SAXException - If any parse errors occur.

setEntityResolver

public void setEntityResolver(EntityResolver er)
Specify the EntityResolver to be used to resolve entities present in the XML document to be parsed.

Specified by:
setEntityResolver in class DocumentBuilder
Parameters:
er - The EntityResolver to be used to resolve entities present in the XML document to be parsed.

setErrorHandler

public void setErrorHandler(ErrorHandler eh)
Specify the ErrorHandler to be used by the parser.

Specified by:
setErrorHandler in class DocumentBuilder
Parameters:
eh - The ErrorHandler to be used by the parser.

getDOMImplementation

public DOMImplementation getDOMImplementation()
Obtain an instance of a DOMImplementation object.

Specified by:
getDOMImplementation in class DocumentBuilder
Returns:
A new instance of a DOMImplementation.

setXIncludeAware

public void setXIncludeAware(boolean state)

Set state of XInclude processing.

If XInclude markup is found in the document instance, should it be processed as specified in XML Inclusions (XInclude) Version 1.0.

XInclude processing defaults to false.

Parameters:
state - Set XInclude processing to true or false

isXIncludeAware

public boolean isXIncludeAware()

Get the XInclude processing mode for this parser.

Overrides:
isXIncludeAware in class DocumentBuilder
Returns:
the return value of the DocumentBuilderFactory.isXIncludeAware() when this parser was created from factory.
Throws:
UnsupportedOperationException - For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown.
Since:
JAXP 1.5, Saxon 8.9
See Also:
DocumentBuilderFactory.setXIncludeAware(boolean)

setStripSpace

public void setStripSpace(int stripAction)
Set the space-stripping action to be applied to the source document

Parameters:
stripAction - one of Whitespace.IGNORABLE, Whitespace.ALL, or Whitespace.NONE
Since:
8.9

getStripSpace

public int getStripSpace()
Get the space-stripping action to be applied to the source document

Returns:
one of Whitespace.IGNORABLE, Whitespace.ALL, or Whitespace.NONE
Since:
8.9

setParseOptions

public void setParseOptions(ParseOptions options)
Set the XML parsing options to be used

Parameters:
options - the XML parsing options. Options set using this method will override any options previously set using other methods; options subsequently set using other methods will modify the parseOptions object supplied using this method
Since:
9.3

getParseOptions

public ParseOptions getParseOptions()
Get the XML parsing options that have been set using setParseOptions and other setter methods

Returns:
the XML parsing options to be used
Since:
9.3
