Parse the text pointed at by the reader as XML, and return a DOM Document interface.

It is recommended that you pass in some sort of recognizable name, such as the filename or URI, with which the reader can be recognized if the parse fails.

The liaison owns the XalanDocument instance, and will delete it when when asked (see DestroyDocument()), or when the liaison is reset, or goes out of scope.

  identifier | used for diagnostic purposes only, some sort of identification for error reporting, default an empty string

Returns:
  DOM document created

Reimplemented from XMLParserLiaison.

void XercesParserLiaison::setBuildBridgeNodes ( | bool newState )

This API is deprecated.

This functions sets the state of the liaison's build-bridge-nodes flag. This flag must be set for the document to be thread safe. It can also be set to true to increase performance. If this flag is set to false, then the thread-safe flag will also be set to false.

Deprecated:
  The Xerces DOM bridge is deprecated.

Parameters:

  newState | The new state for the flag.

void XercesParserLiaison::setBuildMaps ( | bool newState )

This functions sets the state of the liaison's buildMaps flag.

When this flag is true, maps will be built providing Xerces<->Xalan mapping in Wrapper classes.

Note:
  The maps created use a large amount of memory. If only Xalan->Xerces node mapping is required, do not set this to true.

Parameters:

  newState | The new state for the flag.

void XercesParserLiaison::setBuildWrapperNodes ( | bool newState )

This functions sets the state of the liaison's build-wrapper-nodes flag.

This flag must be set for the document to be thread safe. It can also be set to true to increase performance. If this flag is set to false, then the thread-safe flag will also be set to false.

Parameters:

  newState | The new state for the flag.

void XercesParserLiaison::setDoNamespaces ( | bool newState )`[virtual]`

This method allows users to enable or disable the parser's namespace processing.

When set to true, parser starts enforcing all the constraints / rules specified by the NameSpace specification.

The parser's default state is: false.

This flag is ignored by the underlying scanner if the installed validator indicates that namespace constraints should be enforced.

Parameters:

  newState | The value specifying whether NameSpace rules should be enforced or not.

See also:
  getDoNamespaces

void XercesParserLiaison::setEntityResolver ( | EntityResolverType * resolver )`[virtual]`

This method installs the user specified entity resolver on the parser.

It allows applications to trap and redirect calls to external entities.

Parameters:

  handler | A pointer to the entity resolver to be called when the parser comes across references to entities in the XML file.

Reimplemented from XMLParserLiaison.

void XercesParserLiaison::setErrorHandler ( | ErrorHandlerType * handler )`[virtual]`

This method installs the user specified error handler on the parser.

Parameters:

  handler | A pointer to the error handler to be called when the parser comes across 'error' events as per the SAX specification.

Reimplemented from XMLParserLiaison.

void XercesParserLiaison::setExecutionContext ( | ExecutionContext & theContext )`[virtual]`

| Reimplemented from XMLParserLiaison.

void XercesParserLiaison::setExitOnFirstFatalError ( | bool newState )`[virtual]`

This method allows users to set the parser's behaviour when it encounters the first fatal error.

If set to true, the parser will exit at the first fatal error. If false, then it will report the error and continue processing.

The default value is 'true' and the parser exits on the first fatal error.

Parameters:

  newState | The value specifying whether the parser should continue or exit when it encounters the first fatal error.

See also:
  getExitOnFirstFatalError

void XercesParserLiaison::setExternalNoNamespaceSchemaLocation ( | const XalanDOMChar * location )`[virtual]`

This method sets the location for an external schema document for parsing.

Parameters:

  location | A string representing the location of the external schema document

void XercesParserLiaison::setExternalSchemaLocation ( | const XalanDOMChar * location )`[virtual]`

This method sets the location for an external schema document for parsing.

Parameters:

  location | A string representing the location of the external schema document

void XercesParserLiaison::setIncludeIgnorableWhitespace ( | bool include )`[virtual]`

Set the 'include ignorable whitespace' flag.

This method allows the user to specify whether a validating parser should include ignorable whitespaces as text nodes. It has no effect on non-validating parsers which always include non-markup text.

When set to true (also the default), ignorable whitespaces will be added to the DOM tree as text nodes. The method `DOMText::isIgnorableWhitespace` will return true for those text nodes only.

When set to false, all ignorable whitespace will be discarded and no text node is added to the DOM tree. Note: applications intended to process the "xml:space" attribute should not set this flag to false.

Parameters:

  include | The new state of the include ignorable whitespace flag.

See also:
  getIncludeIgnorableWhitespace

void XercesParserLiaison::setIndent ( | int i )`[virtual]`

Set the amount to indent when indent-result="yes".

Deprecated:

Parameters:

  i | number of characters to indent

Reimplemented from XMLParserLiaison.

void XercesParserLiaison::setThreadSafe ( | bool newState )

This functions sets the state of the liaison's thread-safe flag.

This flag must be set for the document to be thread safe. If this flag is set to true, then the build-bridge-nodes flag will also be set to true.

Parameters:

  newState | The new state for the flag.

void XercesParserLiaison::setUseValidation ( | bool b )`[virtual]`

If set to true, validation will be performed.

Validation is off by default.

Parameters:

  b | true to perform validation
