只是为了给大家一个更新，我能够找到一个格式问题的解决方案（更像是一个变通办法）。我现在所做的是使用id.HTML()提取完整的HTML，我将其存储在String对象中。然后，我使用带正则表达式的字符串函数replaceAll()来删除所有HTML标记，而不将所有内容推到一行中。ReplaceAll()函数类似于ReplaceAll(\\<[^>]*>“,”“）。我的整个processhtml()函数类似于：

private String processHTML(String initial) { //initial is the String with all the HTML tags
        String modified = initial;
        modified = modified.replaceAll("\\<[^>]*>",""); //regular expression used
        modified = modified.trim(); //To get rid of any unwanted space before and after the needed data
        //All the replaceAll() functions below are to get rid of any HTML entities that might be left in the data extarcted from the HTML
        modified = modified.replaceAll("&nbsp;", " ");
        modified = modified.replaceAll("&lt;", "<");
        modified = modified.replaceAll("&gt;", ">");
        modified = modified.replaceAll("&amp;", "&");
        modified = modified.replaceAll("&quot;", "\"");
        modified = modified.replaceAll("&apos;", "\'");
        modified = modified.replaceAll("&cent;", "¢");
        modified = modified.replaceAll("&copy;", "©");
        modified = modified.replaceAll("&reg;", "®");
        return modified;
    }

再次感谢你们帮我做这件事

干杯。
