使用正则表达式检测 > < 符号内的文本以对其进行着色

Question

我正在制作一个应用程序来读取 xml 文件。 在代码的某些部分，我使用它来为 '（例如：'hello'）或 " 符号内的文本着色。

regex9.setText("\"(.*?)\"|'(.*?)'"|">(.*?)<");

我想为 > < 符号内的文本着色。 如果我不写 ">(.*?)<" 代码效果很好，但是如果我写它，我会收到以下错误

The operator | is undefined for the argument type(s)
java.lang.String, java.lang.String

如何解决？ 我希望有人读这个

这是完整的代码
