I use this expression but it doesnt work

      startIndex= 'type="photopage">';
      imageUrl=  regexp (imageurl, [startIndex'"([^"]*/'],'tokens');

but unfortunately it doesn't work

[startIndex'"([^"]*/']

is not a valid MATLAB expression. If startIndex is a string then you need a space between it and the ' that starts the literal string. If startIndex is not a string then the result of the [] is not going to be a string and that will not be allowed even if you added the missing space.
