Tagser for Dart #

Overview #

A library for Dart developers.

Simple tag-based document parser. It is not about HTML parsing. You can use whatever tags you want.

Available types of tags:

• Self closing tags: <tag [attributes]/>
• Block tags: <tag [attributes]> Body

Attributes types:

• bool:
• with value:

Methods #

parse(String source) - parsing source string of tags into a list of Tag objects. html(List<Tag> tags) - converting a list of Tag objects into a correct HTML body.

Usage #

A simple usage example:

import 'package:tagser/tagser.dart';

main() {
  var tagser = new Tagser();
  var source = '<line show/><hello> Hello bro </hello><br />';
  
  var tags =  tagser.parse(source);
  var html = tagser.html(tags);
  
  print(html); //prints: <line show="true"></line><hello> Hello bro </hello><br></br>
}

Notes #

• Tag names are case sensitive. Open and close tags in block tag declaration should have the same spelling. It can be changed by passing "ignoreCase": true as option to Tagser
• Attribute names are case sensitive: attribute A and attribute a are not the same

Restrictions #

• All self closing tags should have slash before closing bracket. Using <br> tag without slash will cause an error.
• No spaces allowed between open bracket and tag name: < tag /> - will cause an error
• No spaces allowed between slash and close bracket : <tag / > - will cause an error
• No spaces allowed in attribute declaration:
• <tag A = 'value' /> - error
• <tag A= 'value' /> - error
• <tag A ='value' /> - error

Options #

You can pass options to the Tagser constructor or set them with setOption() method.

Available options:

• ignoreCase - enables or disables case ignoring of opening and closing tag; false by default
