### Converts HTML into text
|
||||
|
||||
|
||||
## Introduction
|
||||
|
||||
html2text is a simple golang package for rendering HTML into plaintext.
|
||||
|
||||
There are still lots of improvements to be had, but FWIW this has worked fine for my [basic] HTML-2-text needs.
|
||||
|
||||
It requires go 1.x or newer ;)
|
||||
|
||||
|
||||
## Download the package
|
||||
|
||||
```bash
|
||||
go get github.com/jaytaylor/html2text
|
||||
```
|
||||
|
||||
## Example usage
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/jaytaylor/html2text"
|
||||
)
|
||||
|
||||
func main() {
|
||||
inputHtml := `
|
||||
<html>
|
||||
<head>
|
||||
<title>My Mega Service</title>
|
||||
<link rel=\"stylesheet\" href=\"main.css\">
|
||||
<style type=\"text/css\">body { color: #fff; }</style>
|
||||
</head>
|
||||
|
||||
<body>
|
||||
<div class="logo">
|
||||
<a href="http://mymegaservice.com/"><img src="/logo-image.jpg" alt="Mega Service"/></a>
|
||||
</div>
|
||||
|
||||
<h1>Welcome to your new account on my service!</h1>
|
||||
|

<p>
|
||||
Here is some more information:
|
||||
|
||||
<ul>
|
||||
<li>Link 1: <a href="https://example.com">Example.com</a></li>
|
||||
<li>Link 2: <a href="https://example2.com">Example2.com</a></li>
|
||||
<li>Something else</li>
|
||||
</ul>
|
||||
</p>
|
||||
</body>
|
||||
</html>
|
||||
`
|
||||
|
||||
text, err := html2text.FromString(inputHtml)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println(text)
|
||||
}
|
||||
```
|
||||
|
||||
Output:
|
||||
```
|
||||
