XML::Encoding Description

XML::Encoding is a Perl module for parsing XML encoding maps. XML::Encoding is a Perl module for parsing XML encoding maps.SYNOPSIS use XML::Encoding; my $em_parser = new XML::Encoding(ErrorContext => 2, ExpatRequired => 1, PushPrefixFcn => &push_prefix, PopPrefixFcn => &pop_prefix, RangeSetFcn => &range_set); my $encmap_name = $em_parser->parsefile($ARGV);This module, which is built as a subclass of XML::Parser, provides a parser for encoding map files, which are XML files. The file maps/encmap.dtd in the distribution describes the structure of these files. Calling a parse method returns the name of the encoding map (obtained from the name attribute of the root element). The contents of the map are processed through the callback functions push_prefix, pop_prefix, and range_set.METHODSThis module provides no additional methods to those provided by XML::Parser, but it does take the following additional options.ExpatRequired When this has a true value, then an error occurs unless the encmap "expat" attribute is set to "yes". Whether or not the ExpatRequired option is given, the parser enters expat mode if this attribute is set. In expat mode, the parser checks if the encoding violates expat restrictions.PushPrefixFcn The corresponding value should be a code reference to be called when a prefix element starts. The single argument to the callback is an integer which is the byte value of the prefix. An undef value should be returned if successful. If in expat mode, a defined value causes an error and is used as the message string.PopPrefixFcn The corresponding value should be a code reference to be called when a prefix element ends. No arguments are passed to this function. An undef value should be returned if successful. If in expat mode, a defined value causes an error and is used as the message string.RangeSetFcnThe corresponding value should be a code reference to be called when a "range" or "ch" element is seen. The 3 arguments passed to this function are: (byte, unicode_scalar, length) The byte is the starting byte of a range or the byte being mapped by a "ch" element. The unicode_scalar is the Unicode value that this byte (with the current prefix) maps to. The length of the range is the last argument. This will be 1 for the "ch" element. An undef value should be returned if successful. If in expat mode, a defined value causes an error and is used as the message string. Requirements: · Perl
