Android also ships a parser that we wrote for Reader mode:

We've talked about extending it to also do phone number/address detection as
well, but haven't tried (reader mode doesn't need to modify the origi

Oh, and the difference between these two is that in the former clones of

Hi Axel,
yeah, we are planning to cover that case about the changing order of inline
elements. See the bottom half of this comment for details:

For alt text, input label placeholders, and other text content from
attributes, I'm planning on bu

Now it isn't clear whether it's a port number or a line number.
Could we somehow fix this?
"http://example.com/"; is equivalent to "http://example.com"; so you could
just ensure that you output a "/" when the path is empty.

Hi,
translating DOM is a bit funky. Generally, you can probably translate
block elements one by one, but you need to persist inline elements.
You should mark up the inline elements in the string that you send to
the translation engine, such that you can support inline markup changing

You could send the string to a worker (if you do this in C++ you won't
