How can I include quotes within a string?
显示 更早的评论
I've been trying to make a string: var = '<meta property="og:title" content="(\w*-*\s*\(*\)*&*;*:*\.*,*/*'*)*"/>'; The problem is that the " '* " causes the doublequotes towards the end to become red, and make the string invalid due to the error "Unbalanced or unexpected parenthesis or bracket."

Look up strings in the help and the example shows that you do a double single quote to get a single single quote:
var = '<meta property="og:title" content="(\w*-*\s*\(*\)*&*;*:*\.*,*/*''*)*"/>'

To you need to use two single quotes to get a single quote inside a string. For example
>> 'You can''t be serious!'
In your case:
var = '<meta property="og:title" content="(\w*-*\s*\(*\)*&*;*:*\.*,*/*''*)*"/>'
should give what you want.

The general rule is that one doubles down on the restricted character...
Example--
>> str='ain''t'
str =
ain't
>>
NB: the doubled quotes to end up with one embedded in the string. One can, of course, also build them by use of the char conversion function--
>> str=['ain' char(39) 't']
str =
ain't
>> q=char(39);
>> str=['ain' q 't']
str =
ain't
>>
The latter shows a temporary variable to shorten the building a little if need more than just one. Sometimes can be easier than trying to work thru the eyestrain sure to result from the double-up exercise; I had more trouble trying to decipher the string you were trying to build than I cared to try to fight thru; hence the example instead.
