        match = match.replace(/style="[^"]+"/gi, '').replace(/style='[^']+'/gi, '')
        match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, '')
        match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, '')
        return match
      })
      newContent = newContent.replace(/style="[^"]+"/gi, function(match, capture) {
        match = match.replace(/width:[^;]+;/gi, 'max-width:100%;').replace(/width:[^;]+;/gi, 'max-width:100%;')
        return match
      })
      newContent = newContent.replace(/<br[^>]*\/>/gi, '')
      newContent = newContent.replace(/\<img/gi, '<img style="max-width:100%;height:auto;display:inline-block;margin:10rpx auto;"')
