字符串到单词的字符串[]

我需要拆分String并获得单词的String[]。我试过这个：字符串到单词的字符串[]

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

但在我的情况下，这是行不通的。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。我的字符串如下所示：

<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 />

这是分析的电子邮件的一部分。那么，我该如何将这些文字转换成一系列文字呢？

你想包含哪些单词？ –

字符串数组应该是什么样子？什么是预期的输出？ –

你的意思是你想要忽略html标签的文字？ – NewUser

此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），并已被转义以用作分裂分离器，还整个字符组必须被内包装a []：

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

在Java regex here上阅读更多信息。

编辑：从CPerkins跟进评论，你也可以使用这个表达式：

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

它所做的是它分裂的所有空格字符和所有非单词字符，这是有点儿我想，你想要什么。

NB：以上只是对您的问题的直接回答，有很多更好的方法来读取/解析HTML。

一个改进，但这将产生空白的多个空数组条目，新行将被视为文本，而不是被剥夺。 – CPerkins

@CPerkins谢谢，用更短/清洁的正则表达式更新了答案。 – maksimov

不用担心。好答案。很好，很干净。 – CPerkins

您可以使用Scanner类。你可以阅读使用文字

while(scanner.hasNext()){}

类型构造。

String noTags = htmlString.replaceAll("\\<.*?\\>", ""); 
    String clearTxt = noTags.replaceAll("[ \t\n.,!;\\(\\)]+", " "); 
    String[] words = clearTxt.split(" ");

如果标签中的文本（像urls可以被忽略），我喜欢这种方法，但是我把noTags.replaceAll（）切换到'“[^ \\ w] +”'放置出更多的非alpha字符。如果需要标记文本，@ maksimov的正则表达式可以被修改为两遍来清除它。 – n0741337

@rebeliagamer好得多，但你的条目有换行符。 n0741337的补充更正了这一点。 – CPerkins

什么的Apache StringUtils.split一些变化？
