NAME

       MKDoc::XML::Tokenizer - Tokenize XML the REX way

SYNOPSIS

         my $tokens = MKDoc::XML::Tokenizer->process_data ($some_xml);
         foreach my $token (@{$tokens})
         {
             print "'" . $token->as_string() . "' is text\n" if (defined $token->text());
             print "'" . $token->as_string() . "' is a self closing tag\n" if (defined $token->tag_self_close());
             print "'" . $token->as_string() . "' is an opening tag\n" if (defined $token->tag_open());
             print "'" . $token->as_string() . "' is a closing tag\n" if (defined $token->tag_close());
             print "'" . $token->as_string() . "' is a processing instruction\n" if (defined $token->pi());
             print "'" . $token->as_string() . "' is a declaration\n" if (defined $token->declaration());
             print "'" . $token->as_string() . "' is a comment\n" if (defined $token->comment());
             print "'" . $token->as_string() . "' is a tag\n" if (defined $token->tag());
             print "'" . $token->as_string() . "' is a pseudo-tag (NOT text and NOT tag)\n" if (defined $token->pseudotag());
             print "'" . $token->as_string() . "' is a leaf token (NOT opening tag)\n" if (defined $token->leaf());
         }

SUMMARY

       MKDoc::XML::Tokenizer is a module which uses Robert D. Cameron REX technique to parse XML
       (ignore the carriage returns):

         [^<]+|<(?:!(?:--(?:[^-]*-(?:[^-][^-]*-)*->?)?|\[CDATA\[(?:[^\]]*](?:[^\]]+])
         *]+(?:[^\]>][^\]]*](?:[^\]]+])*]+)*>)?|DOCTYPE(?:[ \n\t\r]+(?:[A-Za-z_:]|[^\
         x00-\x7F])(?:[A-Za-z0-9_:.-]|[^\x00-\x7F])*(?:[ \n\t\r]+(?:(?:[A-Za-z_:]|[^\
         x00-\x7F])(?:[A-Za-z0-9_:.-]|[^\x00-\x7F])*|"[^"]*"|'[^']*'))*(?:[ \n\t\r]+)
         ?(?:\[(?:<(?:!(?:--[^-]*-(?:[^-][^-]*-)*->|[^-](?:[^\]"'><]+|"[^"]*"|'[^']*'
         )*>)|\?(?:[A-Za-z_:]|[^\x00-\x7F])(?:[A-Za-z0-9_:.-]|[^\x00-\x7F])*(?:\?>|[\
         n\r\t ][^?]*\?+(?:[^>?][^?]*\?+)*>))|%(?:[A-Za-z_:]|[^\x00-\x7F])(?:[A-Za-z0
         -9_:.-]|[^\x00-\x7F])*;|[ \n\t\r]+)*](?:[ \n\t\r]+)?)?>?)?)?|\?(?:(?:[A-Za-z
         _:]|[^\x00-\x7F])(?:[A-Za-z0-9_:.-]|[^\x00-\x7F])*(?:\?>|[\n\r\t ][^?]*\?+(?
         :[^>?][^?]*\?+)*>)?)?|/(?:(?:[A-Za-z_:]|[^\x00-\x7F])(?:[A-Za-z0-9_:.-]|[^\x
         00-\x7F])*(?:[ \n\t\r]+)?>?)?|(?:(?:[A-Za-z_:]|[^\x00-\x7F])(?:[A-Za-z0-9_:.
         -]|[^\x00-\x7F])*(?:[ \n\t\r]+(?:[A-Za-z_:]|[^\x00-\x7F])(?:[A-Za-z0-9_:.-]|
         [^\x00-\x7F])*(?:[ \n\t\r]+)?=(?:[ \n\t\r]+)?(?:"[^<"]*"|'[^<']*'))*(?:[ \n\
         t\r]+)?/?>?)?)

       That's right. One big regex, and it works rather well.

DISCLAIMER

       This module does low level XML manipulation. It will somehow parse even broken XML and try
       to do something with it. Do not use it unless you know what you're doing.

API

   my $tokens = MKDoc::XML::Tokenizer->process_data ($some_xml);
       Splits $some_xml into a list of MKDoc::XML::Token objects and returns an array reference
       to the list of tokens.

   my $tokens = MKDoc::XML::Tokenizer->process_file ('/some/file.xml');
       Same as MKDoc::XML::Tokenizer->process_data ($some_xml), except that it reads $some_xml
       from '/some/file.xml'.

NOTES

       MKDoc::XML::Tokenizer works with MKDoc::XML::Token, which can be used when building a full
       tree is not necessary. If you need to build a tree, look at MKDoc::XML::TreeBuilder.
