golang去掉字符串中的html标签

func trimHtml(src string) string {
    //将HTML标签全转换成小写
    re, _ := regexp.Compile("\<[\S\s]+?\>")
    src = re.ReplaceAllStringFunc(src, strings.ToLower)
    //去除STYLE
    re, _ = regexp.Compile("\<style[\S\s]+?\</style\>")
    src = re.ReplaceAllString(src, "")
    //去除SCRIPT
    re, _ = regexp.Compile("\<script[\S\s]+?\</script\>")
    src = re.ReplaceAllString(src, "")
    //去除所有尖括号内的HTML代码，并换成换行符
    re, _ = regexp.Compile("\<[\S\s]+?\>")
    src = re.ReplaceAllString(src, "
")
    //去除连续的换行符
    re, _ = regexp.Compile("\s{2,}")
    src = re.ReplaceAllString(src, "
")
    return strings.TrimSpace(src)
}
