html2md's Issues

Add iframe support

I want to convert iframe (with youtube src) to video widget

Warning when compiling into native code (dart compile exe)

.pub-cache/hosted/pub.dev/html2md-1.3.1/lib/src/converter.dart:111:37: Warning: Operand of null-aware operation '!' has type 'Node' which excludes null.
 - 'Node' is from 'package:html/dom.dart' ('.pub-cache/hosted/pub.dev/html-0.15.4/lib/dom.dart').
    sibling = util.nextSibling(node.node!);

html2md ^0.3.1 requires html ^0.13.3.

Updating the pubspec to the lastest versions of html package cause pug get to fail.

html2md ^0.3.1 requires html ^0.13.3.
So, because XXXX depends on both html ^0.14.0+2 and html2md ^0.3.1, version solving failed.

blockquote text style not applying

When trying to apply a text style to a blockquote, I am not seeing anything change.

return MarkdownBody(
      styleSheet: MarkdownStyleSheet(
        blockquote: TextStyle(color: Colors.blue),
        blockquoteDecoration: BoxDecoration(
          border: Border(
            left: BorderSide(
              width: 2.0,
            ),
          ),
        ),
        blockquotePadding: const EdgeInsets.symmetric(vertical: 8, horizontal: 16),
      ),
      data: convert('<blockquote>this is a blockquote</blockquote>'),
);

I see the padding & the decoration, but not the text style.

content in <script> tags are not filtered out

This snippet:

final html = """
<!DOCTYPE html>
<head>
	<script>
    console.log("test");
	</script>
</head>
<body>
Hello
</body>
""";
final md = html2md.convert(html);
print(md);

prints out a string that contains 'console.log("test");'. I would have expected only Hello to be included.

The getter 'localName' was called on null.

String html = ''''<div class="postArticle-content js-postField js-notesSource js-trackedPost" data-post-id="ac7a012b7a25" data-source="post_page" data-tracking-context="postPage" data-scroll="native"><section name="1ef3" class="section section--body section--first"><div class="section-divider"><hr class="section-divider"></div><div class="section-content"><div class="section-inner sectionLayout--insetColumn"><h1 name="0b3a" id="0b3a" class="graf graf--h3 graf--leading graf--title">Rtmp Player Android using Exo-Media Player</h1><p name="12c9" id="12c9" class="graf graf--p graf-after--h3">Hello Reader’s, before we start</p><h3 name="e452" id="e452" class="graf graf--h3 graf-after--p">Lets see What is RTMP&nbsp;?</h3><p name="61c0" id="61c0" class="graf graf--p graf-after--h3">RTMP stands for <strong class="markup--strong markup--p-strong">real-time messaging protocol</strong>.

output has \- or \* instead of - or *

I'm not sure why that is, but it seems deliberate. How do I turn that off?

Issue with special characters

Hello! first of all thank you for your work on this library.

I am having an issue transforming an html file with characters like for example: è or when is a space and then a dot.
It shows weird characters like for example Â instead è.

Another case is when I have the symbol ". It shows instead â followed by two boxes.

I hope my problem is more or less clear.

Thank you again!

Ignore Markdown on String

Hi, I am trying to convert HTML with markdown together
String example: ## Heading level 2 <p>html p<p>

Exception with blockquote

Whenever I use the blockquote tag I get an exception:

Another exception was thrown: 'package:flutter/src/widgets/container.dart': Failed assertion: line 59 pos 15: 'decoration != null': is not true.

Example code:
String markdown = html2md.convert('<blockquote>Lorem ipsum...</blockquote>');

Redirect on link click

Hello, I want to redirect when the user clicks on a link like '<a href=""></a>'. How can I track user click on link?

I will be glad if you help.

Edit:
I was able to do this with MarkdownBody. #close

                `MarkdownBody(
                  selectable: true,
                  data: html2md.convert(data),
                  onTapLink: (text, href, title) {
                    try {
                      launch(href ?? "");
                    } catch (e) {
                      print(e);
                    }
                  },
                ),

Links for TOC - Spaces are replaced with _ insted of -

Hi,

after converting a wikipage to markdown using html2md the links of the table of content do not work for me because the spaces are being replaced with _ (underscores) instead of - (hyphens).
Is there a way to change this?

BR, Jennifer

Custom Text Size

How can I set custom text site in HTML data?

Multiple style tag html

listItem parse start error Invalid argument(s): The source must not be null

I'm getting this error all of a sudden when parsing HTML. I'm still trying to analyze the source code to see why, but maybe the library can account for the error? I'm attaching a link to a sample project. all you have to do is run it in debug mode and enable the breakpoints to see the error. It seems to render fine, I believe, but I can't say for certain that something isn't left out/

Exception when using inside ListView(Builder)

When this widget is used inside of a ListView or a ListViewBuilder, the following exception is thrown:
Vertical viewport was given unbounded height.
Some more info:
Viewports expand in the scrolling direction to fill their container.In this case, a vertical I/flutter ( 9925): viewport was given an unlimited amount of vertical space in which to expand. This situation I/flutter ( 9925): typically happens when a scrollable widget is nested inside another scrollable widget. I/flutter ( 9925): If this widget is always nested in a scrollable widget there is no need to use a viewport because I/flutter ( 9925): there will always be enough vertical space for the children. In this case, consider using a Column I/flutter ( 9925): instead. Otherwise, consider using the "shrinkWrap" property (or a ShrinkWrappingViewport) to size I/flutter ( 9925): the height of the viewport to the sum of the heights of its children.

Using shrinkWrap, or wrapping the HTML view widget inside a Container, Flexible, or Expanded does not help.

Tables are not being converted properly

This is slightly complex, but I've narrowed it down to this package.
I'm using this lib to convert html to markdown and then render it in Flutter.
The original Markdown source is here. https://github.com/flutterchina/dio/blob/master/README.md
for comparison.
This is the actual HTML page that's being passed to html2md https://pub.dev/packages/dio
You can see the table in the screenshot

But when it's rendered, it shows like this.

To make a long story short, the table should be rendered like this,
https://github.com/flutterchina/dio/blob/master/README.md

Copy of markdown rendered by html2md

Table support for loose html

The html was generated by Outlook.

The table markdown is invalid if <th> is not added. Also the <br> should be ignored in cells.

final html = '''
<table style="border-collapse:collapse; box-sizing:border-box; height:64px" cellspacing="0" cellpadding="1">
  <tbody>
    <tr>
      <td scope="" style="width:123px; border-color:rgb(171,171,171); border-style:solid; border-width:1px; background-color:transparent; box-sizing:border-box; height:22px">Name<br aria-hidden="true"></td>
      <td scope="" style="width:200px; border-color:rgb(171,171,171); border-style:solid; border-width:1px; background-color:transparent; box-sizing:border-box; height:22px; word-break:break-word; white-space:normal">Value<br aria-hidden="true"></td>
    </tr>
    <tr>
      <td scope="" style="width:123px; border-color:rgb(171,171,171); border-style:solid; border-width:1px; background-color:transparent; box-sizing:border-box; height:41px">Hello,<br aria-hidden="true"></td>
      <td style="width:200px; border-color:rgb(171,171,171); border-style:solid; border-width:1px; background-color:transparent; box-sizing:border-box; height:41px; word-break:break-word; white-space:normal">world from MS 365!<br aria-hidden="true"></td>
    </tr>
  </tbody>
</table>
''';
print(html2md.convert(html));

Actual

| Name  
 | Value  
 |
| Hello,  
 | world from MS 365!  
 |

Expected

| Name    | Value    |
| --- | --- |
| Hello,    | world from MS 365!    |

Compared with Turndown (+ GFM Plugin)
https://guyplusplus.github.io/turndown-plugin-gfm/

[proposal] `convert` accept `dom.Node` parameter

add another convert function like:

String from(
  String Dom.Node, {
  String? rootTag,
  String? imageBaseUrl,
  Map<String, String>? styleOptions,
  List<String>? ignore,
  List<Rule>? rules,
})

In some cases, we have to modify html DOM tree before we pass it to html2md, the new function could avoid extra parsing operations.

Titles in links don't convert properly

Links aren't converted properly if title is provided.

How to reproduce

final linkWithTitle = html2md.convert("<a href="https://example.com" title="Example title">Example content</a>");

What is returned:

[Example content](https://example.comExample title)

What is expected (verifiable via https://domchristie.github.io/turndown/):

[Example content](https://example.com "Example title")

<pre> element not converted to Markdown code

Hi, I'm using your library to convert Wiki pages to Markdown, for example :https://wiki.eclipse.org/Version_Numbering

If a <pre> block is found, it is not converted into a Markdown code block. Example:

<pre>
First development stream
 - 1.0.0

Second development stream
 - 1.0.100 (indicates a bug fix)
 - 1.1.0 (a new API has been introduced)
 The plug-in ships as 1.1.0
</pre>

Do I need to use a code rule for this, or is this a missing feature / configuration?
