求助，关于截取字符串的问题
字符串：

<option value=''> Please Select Color </option><option value='The Same as Picture'> The Same as Picture</option><option value='White'> White</option><option value='Ivory'> Ivory</option><option value='Champagne'> Champagne</option><option value='Pink'> Pink</option><option value='Silver'> Silver</option>
