Java find not so specific String
<p>I have product description, furniture, many words and I need to find the size (dimensions) of the product. The problem is, the format of the description of the size is not always the same. Only one thing stays same : letter "x" between the numbers, and if there is "x" in the text and another "x" just a few chars away, it is for sure the size description.</p>

<p>Possible formats of size description /all of them appears/:<br>
size:110x76x60 cm   /without spaces/<br>
size: 150 x 64,5 x 200 cm  /with spaces/<br>
Size: l90 x h55 x w60 cm   /as length, height, width/<br>
Size: 149 x v110 x h40  /only some numbers have letters before them/</p>

<p>And not to mention, the numbers dont have to be 3 digits, they can be only 2 digits. <br> But if it is easier to do it for only one type of format, I take it :) and I let the program check the whole list for all the possible formats again and again. </p>
