Regex Patterns in Java

Question

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;

Should return:

Hello World!

If you are parsing HTML you should use an HTML parser.

"split" takes a regex as the first argument

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])

THanks for the response but I need to use Regex expressions

if you check the API for String.split, technically it is a regex :)
