    		htmlContent = htmlContent.replaceAll("\\s*",""); //去除空格
    		String regEx_html="<[^>]+>";                      //HTML标签正则表达式
    		Pattern pattern = Pattern.compile(regEx_html);
    		Matcher matcher = pattern.matcher(htmlContent);
    		while (matcher.find()){
    			htmlContent = htmlContent.replace(matcher.group(),"");
