# html-parser
Simple HTML to JSON parser use Regexp and String.indexOf

## Install

```shell
npm install htmlstr-parser

## Update
微信建议nodes属性绑定数组,所以htmlParse(html)返回值改成数组
旧版本输出属性名根据微信文档改变,微信文档地址: https://mp.weixin.qq.com/debug/wxadoc/dev/component/rich-text.html
```
"tag":"root" => "name": "div"
"type": "Element" || "Text" => type: "node" || "text"
"attributes": {} => attrs: {"class": "parse-*"} // 增加默认class(parse-div,parse-img, parse-a...),可外部修改转换后元素的样式
"content": "content..." => "text": "text..." // 文本节点内容
```

## Basic usage

```javascript
import htmlParser from "htmlParser"
data: {
nodes: []
}

var html = "<div style='height:10rpx;width: 20rpx;'>1<p>2<br/><a href='http://www.baidu.com'>3</a></p><p>2</p></div>"
htmlParser(html)
this.setData({
nodes: htmlParser(this.data.html)
})

```
wxml:
```wxml
<rich-text class="rich-text" nodes="{{nodes}}"></rich-text>
```
### Output
```javascript

{
"tag": "root",
[{
"name": "div",
"children": [{
"type": "Element",
"tagName": "div",
"attributes": {
"type": "node",
