Question

我需要拆分String并获取String[]个字词。我试过这个：

String[] plain = plainText.split(" ,;<>/[(!)*=]");

但在我的情况下，这不起作用。拆分后，数组plain仍然只有一个值，它是字符串plainText中的整个字符串。我的字符串看起来像这样：

<table class="content" border="0" cellpadding="0" cellspacing="0" style="width:540px;" bgcolor="#ffffff">
            <tr>
                <td align="left" valign="top">
                    <font color="#666666" face="Arial, Verdana" size="1">
                    eBay Inc.<br />

这是已解析的电子邮件的一部分。那么如何将这个文本转换成一个单词数组？

Answer 1

这个正则表达式是错误的，因为它的一些字符是正则表达式控制字符（例如[，(，*等）并且必须被转义才能用作拆分分隔符，整个字符组也必须包含在[]：

中

String[] plain = plainText.split("[ ,;<>/\\[\\(!\\)\\*=\\]]");

详细了解Java regex here。

修改：要跟进CPerkins的评论，您还可以使用此正则表达式：

String[] plain = plainText.split("[\\s^\\W]+");

它的作用是分割所有空格字符和所有非字字符，我认为这就是你想要的。

NB ：以上只是您问题的直接答案，有更好的方法来阅读/解析HTML。

Answer 2

您可以使用Scanner类。您可以使用

阅读单词

while(scanner.hasNext()){}

类型构造。
