C# Regular Expression - Something or Nothing

Question

I have two types of possible lines to get information from:

<td class="forecast">106.2%</td>

or

<td class="forecast"></td>

And I want to get what is inside, it can be something, like a number, or it can be exactly nothing, not even a white space.

I have the following piece of regular expression:

<td class=\"forecast\">\\s*(.+?)\\s*</td>

It works, when there is content inside the HTML cell, but if there is nothing, it gets the following part of the HTML code.

Does someone knows how to solve this?

Answer 1

Just change the (.+?) to (.*?).

• + = One or More
• * = Zero or More
