Class SimpleXMLParser

java.lang.Object

com.gitlab.pdftk_java.com.lowagie.text.pdf.SimpleXMLParser

public class SimpleXMLParser
extends Object

A simple XML and HTML parser. This parser is, like the SAX parser, an event based parser, but with much less functionality.

The parser can:

• It recognizes the encoding used
• It recognizes all the elements' start tags and end tags
• It lists attributes, where attribute values can be enclosed in single or double quotes
• It recognizes the <[CDATA[ ... ]]> construct
• It recognizes the standard entities: &, <, >, ", and ', as well as numeric entities
• It maps lines ending in \r\n and \r to \n on input, in accordance with the XML Specification, Section 2.11

The code is based on http://www.javaworld.com/javaworld/javatips/javatip128/ with some extra code from XERCES to recognize the encoding.

Method Detail

parse

public static void parse(SimpleXMLDocHandler doc,
                         InputStream in)
                  throws IOException

Parses the XML document firing the events to the handler.

Parameters:

doc - the document handler

in - the document. The encoding is deduced from the stream. The stream is not closed

Throws:

IOException - on error

getJavaEncoding

public static String getJavaEncoding(String iana)

Gets the java encoding from the IANA encoding. If the encoding cannot be found it returns the input.

Parameters:

iana - the IANA encoding

Returns:

the java encoding

parse

public static void parse(SimpleXMLDocHandler doc,
                         Reader r)
                  throws IOException

Throws:

IOException

parse

public static void parse(SimpleXMLDocHandler doc,
                         SimpleXMLDocHandlerComment comment,
                         Reader r,
                         boolean html)
                  throws IOException

Parses the XML document firing the events to the handler.

Parameters:

doc - the document handler

r - the document. The encoding is already resolved. The reader is not closed

Throws:

IOException - on error

escapeXML

public static String escapeXML(String s,
                               boolean onlyASCII)

Escapes a string with the appropriated XML codes.

Parameters:

s - the string to be escaped

onlyASCII - codes above 127 will always be escaped with &#nn; if true

Returns:

the escaped string

decodeEntity

public static char decodeEntity(String s)
