Dart port of html5lib. For parsing HTML/HTML5 with Dart. Works in the client and on the server.

html's Introduction

A Dart implementation of an HTML5 parser.

Usage

Parsing HTML is easy!

import 'package:html/parser.dart';

void main() {
  var document = parse(
      '<body>Hello world! <a href="www.html5rocks.com">HTML5 rocks!');
  print(document.outerHtml);
}

You can pass a String or list of bytes to parse. There's also parseFragment for parsing a document fragment, and HtmlParser if you want more low level control.

Background

This package was a port of the Python html5lib library.

html's Issues

always include a \n in outerHtml

seems to be commonly the case that you want it when dumping code to a file.

fix htmlinputstream, tokenizer to use codepoints and build strings as late as possible

<img src="https://avatars.githubusercontent.com/u/5479?v=3" align="left" width="96" height="96"hspace="10"> Issue by sethladd
Originally opened as dart-lang/sdk#16704

There's a todo explaining, but I think we can radically simplify this class and base it on codepoints instead of building up string chunks. I'd also like to remove the RegExp that is used for "charsUntil"

This could be done in two phases also, first simplify inputstream then tokenizer

Update/remove 65-bit tests for Dart2

Reproduce:

pub run test test/tokenizer_test.dart -N '65-bit'
works on Dart stable
fails on Dart 2.0.0-dev.15

DART_VM_OPTIONS='--no_limit_ints_to_64_bits' pub run test test/tokenizer_test.dart -N '65-bit'
Works on Dart 2.0.0-dev.15

See failures:
Before: https://travis-ci.org/dart-lang/html/jobs/326615035
After: https://travis-ci.org/dart-lang/html/jobs/327414723

Test fails on the vm: html/test/selectors/level1_baseline_test

When run on the vm, one of the subtests of test/selectors/level1_baseline_test fails:

FAIL: Detached Element.querySelectorAll: Attribute whitespace-separated list selector, matching custom data-* attribute with unicode escaped value: [data-attr-whitespace~="\0000e9"]

This should be added to a status file, or removed from the test, or fixed, so the package buildbot turns green.

Internal type error with duplicate attributes and generateSpans: true

Repro:

import 'package:html/parser.dart' as html;

void main(List<String> args) {
  var dom = html.parse('<div duplicate duplicate>', generateSpans: true);
  print(dom.querySelector('div').attributeSpans);
}

This results in:

Unhandled exception:
type 'ParseErrorToken' is not a subtype of type 'StartTagToken' in type cast where
  ParseErrorToken is from package:html/src/token.dart
  StartTagToken is from package:html/src/token.dart

Please bump version to 1.0 when stable

Pre-1.0 version numbers make it look like the package is not yet ready for use.

Unable to query nodes that exist at the same time use tag and class

		print(doc.querySelectorAll('div.aa'));//ok
		print(doc.querySelectorAll('div.aa span'));//error
	});
}

improve error table

Right now errors are a string -> string map. It would be better to have them match the planned internationalized message format.

Upgrade from comment-based generics syntax

The comment-based generics syntax will be removed from the Dart SDK tools (like DDC, analyzer) "soon." dart-lang/sdk#28796

Such syntax (like in map) needs to be updated, and the minimum Dart SDK in pubspec.yaml needs to be bumped to 1.21, when the non-comment-based syntax was introduced.

Migrate tests from unittest package to test package

The unittest package is long deprecated. Please migrate tests to use the new test package.

html5lib parses extremely slow certain type of content

<img src="https://avatars.githubusercontent.com/u/148256?v=3" align="left" width="96" height="96"hspace="10"> Issue by kaisellgren
Originally opened as dart-lang/sdk#15076

The following code demonstrates a very slow parsing speed:

  http.read('https://www.facebook.com/MARCA').then((c) {
    htmlParser.parse(c);
  });

For most websites out there, it's fast, but for a few and this site in particular, it parses in around 20-25 seconds.

Template tag within table wrongly reports voodoo error

From spec: https://html.spec.whatwg.org/#parsing-main-intable

12.2.5.4.9 The "in table" insertion mode

When the user agent is to apply the rules for the "in table" insertion mode, the user agent must handle the token as follows:

...

A start tag whose tag name is one of: "style", "script", "template"
An end tag whose tag name is "template"
Process the token using the rules for the "in head" insertion mode.

tagName should return an UPPERCASE string

Sigh. This will break like everyone using us. D'oh!

CSS rects should use getBoundingClientRect instead of offsetWidth and offsetHeight

Getters like contentEdge, paddingEdge, marginEdge and borderEdge use offsetWidth and offsetHeight which both return a rounded value of the width and height of the element. This results in incorrect arithmetic when programmatically calculating element sizes. Only getBoundingClientRect returns fractional values. I think this would be the correct way to provide these properties and would match how jQuery works too.

Parsing unicode characters

How do we parse special characters like   and

क्य ?? Please help team

need raw DOM API

compatible with https://dom.spec.whatwg.org
we'll have a browser API like this too, so would be good to get the server side hooked in as well

implement template parsing

the <template> element parsing it not handled, because the html5lib port predates it

When HtmlParser.lowercaseAttrName is false, span maps still use lower case names

This seems inconsistent.

they're warnings in html, but it would be good to explain this :)

html5lib test case where two equivalent selectors give different result

Originally opened as dart-lang/sdk#21820

This issue was originally filed by [email protected]

What steps will reproduce the problem?

import 'package:html5lib/dom.dart' as dom;
import 'package:unittest/unittest.dart';

main() {
  group('Select b inside span', () {
    final div = new dom.Element.html(
        r"""<div><span class="prep_nove"><b>1</b></span></div>""");

    test('using two separate selectors', () {
      var b = div.querySelector("span.prep_nove").querySelector("b");
      expect(b, isNotNull);
      expect(b.text, '1');
    });
    test('using one combined selector', () {
      var b = div.querySelector("span.prep_nove b");
      expect(b, isNotNull);
      expect(b.text, '1');
    });
  });
}

What is the expected output? What do you see instead?

Observatory listening on http://127.0.0.1:56811

cleanup: use char codes instead of strings

related to #7, there's a lot of too-eager char codes -> string conversions, and a lot of 1 character strings. It'd be nice to have inputstream.dart return int and List<int> and have tokenizer.dart consume those, not stringifying until ready to send tokens to the parser. Also, for character/space tokens it would be nice to preserve it even longer, and fix the treebuilder insertText code path

examples can show up on the pub site

The pub site can show example code for a package.

Incorrect spans generated for HTML with higher-plane unicode characters

When parsing HTML that includes characters like "🍋", the start and end FileLocations are generated incorrectly.

Here's a short repo:

import 'package:html/dom.dart';
import "package:html/parser.dart";
import "package:source_span/source_span.dart";

void main() {
  final dom = parse(contents,generateSpans: true);
  final Element element = dom.querySelectorAll("link").single;
  final span = element.sourceSpan;
  final spanCopy = new SourceSpan(span.start, span.end, contents);
}

const contents = """
<head>
    <meta charset="UTF-8">
    <title></title>
    <link rel="alternate" type="application/rss+xml" title="ArtLung &raquo; Limones 🍋 Comments Feed" href="subdirectory/other.html" />
</head>
""";

This will throw the following error:

Unhandled exception:
Invalid argument(s): Text "<head>
    <meta charset="UTF-8">
    <title></title>
    <link rel="alternate" type="application/rss+xml" title="ArtLung &raquo; Limones 🍋 Comments Feed" href="subdirectory/other.html" />
</head>
" must be 130 characters long.
#0      new SourceSpanBase (package:source_span/src/span.dart:85:7)
#1      new SourceSpan (package:source_span/src/span.dart:34:11)
#2      main (file:///Users/filiph/dev/linkcheck/test/source_span_bug.dart:9:24)
#3      _startIsolate.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:265)
#4      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:151)

This is not an issue with package:source_span — when I create the span manually, without parse(), copying it works okay.

remove string concatenation

Originally opened as dart-lang/sdk#16705

The tokenizer, parser, simpletree use string concat. Need to switch this to StringBuffers or Lists+join

querySelector return null if query with 2 classes

import 'package:html/parser.dart';
import 'package:html/dom.dart';

void main() {
  final doc = parse('<div class="aa bb"><div class="cc"><div/></div>');
  print(doc.querySelector('.aa.bb .cc'));
  }

*It works fine with .aa .cc

api documentation for registerElement contains an error

https://api.dartlang.org/1.14.1/dart-html/HtmlDocument/registerElement.html
It does not mention extendsTag option must be given to the registerElement method for extending the InputElement.

Without the option, dartium tells you you must extend HtmlElement.

(Moved from dart-lang/web-ui#217)

These are a couple minor improvements we can do to give early feedback to our users:

when there is a mismatch close tag, show the location of the open-tag that wasn't closed correctly
when a component close tag is missing (either use a warning always, or at least if such component has no <content> tags in it)

fix strong mode analyzer issues

there are... a lot. thanks @devoncarew for finding these

Implement node.query and node.queryAll in html5lib to include features like:
- id search "#foo"
- multiple tag search "div,span"
- and more!

I know that the readme talks about sanitizing being still unimplemented.

I made this task so that me and others can follow this particular work (couldn't find anything with the search).

We are using Web UI in our project and sometimes new SafeHtml.unsafe(...) even for user-supplied content which is bad, but we have to in order to support custom user-supplied HTML. Our hopes are that sooner or later we can replace those with code that sanitizes the bad input and makes sure it's clean by leveraging a whitelist approach.

publish a 0.13.3 version

@kevmoo, can you publish a new version of this? I'd like to capture the fix from #68. I believe the next version will be 0.13.3 - I updated the changelog to say such.

No span in "end-tag-too-early" error

Found this while fuzzing the angular analyzer.

<li><x</y><li>

The resulting ParseError "end-tag-too-early" contains no error span.

the lis seem to be important, though x, y, and if any of these tags have properties don't seem to be.

NodeList is missing support for the length setter

Does dart:html have this bug too?

DOM will eventually need CSS parsing

to implement the CSSOM, e.g. CSSStyle* IDL types

error getting attribute spans even though attributes exist on malformed html

I'm parsing this with quirks = true as document, and then trying to find the attributeSpans when the attributes map isn't empty.

This is the html:

<button attr<="value"></button>

this is the code:

     element.attributes.forEach((name, String value) {
      if (name is String) {
        String lowerName = name.toLowerCase();
        int nameOffset = element.attributeSpans[lowerName].start.offset;

and this is the error:

type 'ParseErrorToken' is not a subtype of type 'StartTagToken' in type cast where\n ParseErrorToken is from package:html/src/token.dart\n StartTagToken is from package:html/src/token.dart\n\n#0 Object._as (dart:core-patch/object_patch.dart:74)\n#1 Node._ensureAttributeSpans (package:html/dom.dart:286)\n#2 Node.attributeSpans (package:html/dom.dart:173)\n#3 HtmlTreeConverter._convertAttributes.<anonymous closure> (package:angular2_analyzer_plugin/src/resolver.dart:278)

At the time of error in the debugger

$ p attributes.length
= 1
$ p attributes['attr<']
= 'value'
$ p sourceSpan.text
= '<button attr<="value">'

and the current token is

Token _current = ParseErrorToken {  ⊟  
FileSpan span = _FileSpan {  ⊟  
final SourceFile file = SourceFile {  ⊞  }
final int _start = 0
final int _end = 13
}
StringBuffer _buffer = null
String _string = 'invalid-character-in-attribute-name'
Map messageParams = null
}

perf: avoid string concat

This bug appears to have been lost amongst the issue tracker moves. Basically, performance is bad in cases that force a lot of concatenation in the parser. This is a python-ism that did not translate well to Dart. We need to StringBuffer these, or keep as List for as long as possible.

getElementById does not support ids with point like "my.id"

As getElementById(id) is defined by :

Element getElementById(String id) => querySelector('#$id');

It doesn't work with ids like my.id because it is handled as finding an element with id my and class id.

A workaround is:

//var elmt = getElementById('my.id);
var elmt = querySelectorAll('[id]').firstWhere((e)=> e.id == 'my.id');

Incomplete HTML displaying errors incorrectly

Originally opened as dart-lang/sdk#16981

This issue was originally filed by [email protected]

With a structure with insufficient end div tags

e.g.

</div>
</body>

A warning is displayed associated with the /body tag below:

"web/....html:163:1: Unexpected end tag (div). Missing end tag (body)."

It should be reporting that there was a missing end tag for (div) instead. This made fixing the difficult slightly tricky.

The page used polymer.

dart:html compatible library

we should expose a library where interfaces are 100% dart:html compatible. It's fine if they throw unsupported, the important bit is to have full API compatibility. This allows code to be written that can work on either environment by simply swapping the import.

https://github.com/dart-lang/html/blob/master/lib/dom.dart isn't a bad start, but it has a ways to go.

Possibly quick idea to get started: reflect over dart:html using package:analyzer, and then dump the APIs. Use that as the starting point, then fill in the implementations where we can (everything related to parsing, DOM traversal, query selector, etc).

Google code link to the original python html5lib in readme could be changed to github URL

The current link in the readme points to the google code page. Since it is now moved to github it could be changed.

Hi, Can not work on gb2312

Please help, thanks

 const url = "http://www.ysts8.com/index_hot.html";
    var response = await get(url, headers: Utils.header);

    var html = parse(response.body, encoding: "gb2312");
    var tipsRoot = html.querySelector("div.pingshu_ysts8_i");
    var items = tipsRoot.querySelectorAll("li.qx");
    items.forEach((f) {
      print(f.text);
    });

dependencies

http: ^0.11.3+16
html: any

Question: Use this package or html5lib?

Like the title says, should I use this package, or html5lib?

html5lib: full (or at least common) selector support

only type (i.e. tag name) selectors are supported right now, e.g. "div"

most useful ones, IMHO

ids
classes
descendants
children
attributes

basically everything in simple selectors, other than psuedos:
http://www.w3.org/TR/css3-selectors/#simple-selectors

and the combinators, except sibling:

don't warn about missing html, doctype, and body tags in component HTML files

I don't see these warnings in the current WhatWG spec, for example:
http://www.whatwg.org/specs/web-apps/current-work/multipage/tree-construction.html#the-before-head-insertion-mode

pull in html5tests via git submodule

one of the html5lib developers mentioned this on our old github repository. we can pull in the tests via submodule rather than checking in. The tests have seen a lot of updates in the 2+ years since my original port
