Constructor Detail

DTDParser

public DTDParser(Reader in)

Creates a parser that will read from the specified Reader object

DTDParser

public DTDParser(Reader in,
                 boolean trace)

Creates a parser that will read from the specified Reader object

Parameters:

in - The input stream to read

trace - True if the parser should print out tokens as it reads them (used for debugging the parser)

DTDParser

public DTDParser(File in)
          throws IOException

Creates a parser that will read from the specified File object

DTDParser

public DTDParser(File in,
                 boolean trace)
          throws IOException

Creates a parser that will read from the specified File object

Parameters:

in - The file to read

trace - True if the parser should print out tokens as it reads them (used for debugging the parser)

DTDParser

public DTDParser(URL in)
          throws IOException

Creates a parser that will read from the specified URL object

DTDParser

public DTDParser(URL in,
                 boolean trace)
          throws IOException

Creates a parser that will read from the specified URL object

Parameters:

in - The URL to read

trace - True if the parser should print out tokens as it reads them (used for debugging the parser)

Method Detail

parse

public DTD parse()
          throws IOException

Parses the DTD file and returns a DTD object describing the DTD. This invocation of parse does not try to guess the root element (for efficiency reasons)

parse

public DTD parse(boolean guessRootElement)
          throws IOException

Parses the DTD file and returns a DTD object describing the DTD.

Parameters:

guessRootElement - If true, tells the parser to try to guess the root element of the document by process of elimination

removeElements

protected void removeElements(Hashtable h,
                              DTD dtd,
                              DTDItem item)

parseTopLevelElement

protected void parseTopLevelElement()
                             throws IOException

                  throws IOException
