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.AUTHOR
