preventing regex to capture too early

Question

I have the following text which I will be running regex on. I want to match the "selected" option and get its value. In this example Haiti is the selected option.

<option value="502">Guatemala (+502)</option><option value="224">Guinea (+224)</option><option value="245">Guinea-Bissau (+245)</option><option value="592">Guyana (+592)</option><option value="509" selected >Haiti (+509)</option><option value="504">Honduras (+504)</option><option value="852">Hong Kong (+852)</option>

I tried this regex

<option value="(.*?)" selected >

which matches

224">Guinea (+224)</option><option value="245">Guinea-Bissau (+245)</option><option value="592">Guyana (+592)</option><option value="509

I want to match "509" only. Any solutions for this?

Answer 1

你匹配第一个<option value="所有东西，试着不匹配引号，即<option value="([^"]*)" selected > （意思是双引号之间只允许双引号:)）。
