wxParse gitHub地址：https://github.com/icindy/wxParse
目前项目已停止维护了，原因未知。
使用wxParse在微信小程序里加载此富文本：
2. wxParse应用
2.1. js
const WxParse = require('../../utils/wxParse/wxParse.js')
Page({

},
onLoad() {
var article = this.data.content.replace(/"/g, '');;
var that = this;
WxParse.wxParse('article', 'html', article, that, 5);
}
})
2.2. html
<import src="../../utils/wxParse/wxParse.wxml"/>
<view class="wxParse">
<template is="wxParse" data="{{wxParseData:article.nodes}}"/>
</view>
2.3. css
@import "../../utils/wxParse/wxParse.wxss";
2.4. 显示效果
在小程序里的显示效果如下：
2.5. 注意
- 富文本字符串中不应该有一些特殊字符，例如
"； - 如果加载富文本html，当字符串显示了出来，那一般就是富文本字符串中包含了一些特殊字符，电脑浏览器可能识别，在微信小程序上会加载不出来；
- 在加载富文本的时候，去掉
"即可。
let content = fishPublishInfo.content.replace(/"/g, '');
WxParse.wxParse('article', 'html', content, this, 5);
