Regex Patterns in Java

I am using Regex Patterns and I need to check that the beginning of the String is an HTML Simple Text and return that String. So for example:

Hello World!<TAG> &nsbp;

Shoul开发者_运维技巧d return:

Hello World!

Remember that if you're parsing large sections of text or entire files, you should force the String into a new reference otherwise you may get a memory leak due to substrings.

new String("Hello World!<TAG> &nsbp;".split("<")[0])

"Hello World!<TAG> &nsbp;".split("<")[0]

should return Hello World!.
