Replace all characters between Regular expression

I want to replace an entire String with "" (an empty string).

I have a string, like the one that follows:

<code code="34068-7"

However, the number at the end can be anything (in this example it is 7), So, basically, I want to replace everything between < and the final number, including the < and the final number, with "". Since the number can be any digit, how can I do this with regex?

I have tried this:

 line = line.replaceAll("<code.*?\">","");

Can anyone suggest a way to achieve this?

Adding to ernest_k's answer, you can also replace numbers in regex with \d for better readability. So the regex would be:

<code code=\"[\d-]+\"

Try this:

line = line.replaceAll("(?<=\\<)code.*?\"", "");

This lookbehind regexp will ensure that the < at the beginning of your string will not be replaced by "", so your example output will be

<34068-7"

You can use this pattern:

line = line.replaceAll("<code code=\"[0-9-]+\"", "");

That pattern is only flexible about the data in the attribute value, the rest is assumed static.
