Extract two words from a cell in to another cell in google spreadsheet

Question

I am new to google spreadsheets & want to copy class names mentioned in range c10 in to b3. I am trying to use following formula which I know is wrong:

=         


        

Answer 1

There may be easier ways, but try (in B3):

=join(" ", regexextract(C10, "class="&char(34)&"(.+?)"&char(34)&">.+class="&char(34)&"(.+?)"&char(34)&">"))
