## Note

For anyone who is using Elm 0.19 and blocked by this library, consider using [hecrj/html-parser](https://package.elm-lang.org/packages/hecrj/html-parser/latest/) for now. It seems still WIP but passed the same test cases. I think that means the most difficult part of the HTML spec should be already covered (e.g. `
` does not need a closing tag). Also, it uses the official parser `elm/parser` which I was planning to use in the newer version. So I think contributing to `hecrj/html-parser` is the fastest path for everyone getting happy :)

[![Build Status](https://travis-ci.org/jinjor/elm-html-parser.svg)](https://travis-ci.org/jinjor/elm-html-parser)

Parse HTML in Elm! ([DEMO](https://jinjor.github.io/elm-html-parser/))

## Parse

```elm

import HtmlParser as HtmlParser exposing (..)

parse "text" == [ Text "text" ]

parse "
Hello
World
"

  == [ Element "h1" [] [ Text "Hello", Element "br" [] [], Text "World" ] ]


parse """Example"""

  == [ Element "a" [("href", "http://example.com")] [ Text "Example" ] ]

```

## Query

```elm

import HtmlParser exposing (..)

import HtmlParser.Util exposing (..)

table = """

  

  

   

   

    1

    2

    3

   

   

    2

    3

    4

   

  

  

"""

( parse table

  |> getElementsByTagName "tr"

  |> mapElements

    (\_ _ innerTr ->

      innerTr

        |> mapElements (\_ _ innerTd -> textContent innerTd)

        |> String.join "\t"

        |> String.trim

    )

  |> String.join "\n"

) == "1\t2\t3\n2\t3\t4"
