WEBVTT 00:01.450 --> 00:02.410 Okay, everyone. 00:02.410 --> 00:09.070 So now we are getting the number of guests that each room can accommodate inside of the listings. 00:09.100 --> 00:13.120 We also want to get the bedrooms, the baths and the baths. 00:13.270 --> 00:19.270 And the way we're going to do that is pretty much the same method as we are using in here. 00:19.690 --> 00:25.150 So if you want to go ahead and do that yourself, get some practical exercise out of it. 00:25.150 --> 00:28.870 I recommend that you pause the video and try to do that. 00:28.900 --> 00:36.040 One thing to keep in mind before you do it is that I made a mistake here, because if we don't return 00:36.040 --> 00:41.320 any matches from this regular expression up here, this value becomes null. 00:41.320 --> 00:48.640 It doesn't have a length of zero, so you just check if it is not null instead of this. 00:49.120 --> 00:55.420 Okay, so if you want to do this exercise yourself, go ahead and pause the video now. 00:57.320 --> 01:05.360 And now for the rest of you who are lazy or just want to see how we do it, we go ahead and I do it 01:05.360 --> 01:08.780 now and you will follow along with me, of course. 01:09.170 --> 01:14.540 So we have we will write a function called return matches. 01:15.590 --> 01:19.310 Because what we're doing is so similar to this. 01:20.000 --> 01:26.990 And so we pass in the room text and the regular expression we're going to test and we have the regular 01:26.990 --> 01:35.540 expression matches which rerun on room text with the regular expression. 01:35.540 --> 01:44.570 And by default, we're going to set the result here of non-applicable and. 01:45.860 --> 01:48.760 Just going to make the text a bit bigger for you. 01:49.930 --> 02:02.260 And then we check if the regex matches is not null and if it's not null, then we just return the mean. 02:02.260 --> 02:06.520 We set the result to be the first match. 02:08.180 --> 02:15.410 And if we don't, I mean, if the regex matches is null, then there's something wrong or our regex 02:15.440 --> 02:18.050 is not working as much as we want to. 02:18.080 --> 02:28.250 So we return a no regex matches exception exception and we say no regex matches found for the regex 02:28.250 --> 02:30.140 match we're trying to use. 02:30.530 --> 02:34.280 So we can debug it later and look at the text and so on. 02:34.640 --> 02:38.060 And finally we will return the result. 02:39.530 --> 02:40.280 Okay. 02:41.220 --> 02:50.820 And so we're going to go ahead and delete all this and we'll just say return matches, pass in the room 02:50.820 --> 02:55.470 text and the regular expression, which I just deleted. 02:55.710 --> 03:00.090 And that was the plus guest. 03:02.000 --> 03:02.840 All right. 03:04.180 --> 03:08.470 And actually we're supposed to be guest allowed, not guest match. 03:09.610 --> 03:15.580 And yeah, now we can go ahead and write for the bedrooms. 03:17.110 --> 03:18.430 Return matches. 03:19.210 --> 03:20.590 Room text. 03:21.700 --> 03:24.530 And we pass in a number. 03:24.550 --> 03:29.980 I expect it to be a number and bedroom and pass. 03:32.760 --> 03:40.650 Return matches and then a number and path. 03:42.850 --> 03:43.750 Then we have bats. 03:43.780 --> 03:46.330 Also return matches. 03:47.230 --> 03:48.340 Room Text. 03:53.330 --> 03:53.690 Bit. 03:54.530 --> 03:55.090 Yeah. 03:55.880 --> 04:05.120 So and then I instead of having these console log down here, I want to return an object with all of 04:05.120 --> 04:08.540 the values we got here. 04:13.480 --> 04:14.050 That's. 04:16.140 --> 04:21.360 And then instead I want to say const result. 04:22.110 --> 04:22.800 Here. 04:22.800 --> 04:33.150 So the the object returned from the method here is coming down here and we want to console log that 04:33.150 --> 04:33.930 instead. 04:36.960 --> 04:38.760 And let's see. 04:38.760 --> 04:46.140 So I also want to if there's an exception, it's going to throw a mean display this error so we can 04:46.140 --> 04:50.280 see what regular expression is at fault here. 04:50.280 --> 04:59.160 And I also want to show the I also want to see the URL so we can go and check the page that's failing 04:59.910 --> 05:04.530 and I'll put that on top of the error. 05:04.530 --> 05:12.630 And another thing I think that, oh, I forgot to put in the price per night in my values. 05:12.630 --> 05:16.320 I think that's pretty important and. 05:17.310 --> 05:17.820 Okay. 05:17.820 --> 05:28.200 And so the URL I also want to pass in the room text in my exception if I got an exception. 05:28.200 --> 05:36.300 So I will write console error room text and now room text. 05:36.330 --> 05:37.770 We need to. 05:39.710 --> 05:42.380 Actually, I forgot to have my selector here. 05:42.950 --> 05:44.450 That's a mistake. 05:45.350 --> 05:47.810 You probably have it in your. 05:49.160 --> 05:49.760 Code. 05:49.760 --> 05:50.990 That's just my mistake. 05:50.990 --> 05:52.100 Then I deleted it. 05:52.550 --> 05:56.810 But we actually need to move this room text variable. 05:57.610 --> 06:02.350 To the outer scope so we can display displays it. 06:02.710 --> 06:05.560 Display it inside of the catch here. 06:09.120 --> 06:09.960 Like that. 06:13.360 --> 06:15.850 And let's see how it goes. 06:35.090 --> 06:35.930 Okay. 06:35.940 --> 06:40.230 Room Testmatch is not a function. 06:40.230 --> 06:43.230 Yeah, that's because I need to have a text on. 06:43.950 --> 06:45.630 Sorry, guys. 06:47.630 --> 06:51.080 That is probably only my code that has that error. 06:51.350 --> 06:56.000 I don't know why I missed the room text definition. 07:04.620 --> 07:06.850 Okay, so let's see. 07:06.870 --> 07:08.310 One bedroom, one bath. 07:08.340 --> 07:09.240 One bath. 07:10.050 --> 07:13.050 Yeah, that seems to match what we have. 07:14.130 --> 07:18.300 And okay, so we get a error here. 07:18.660 --> 07:23.410 You see, we get no regex regex matches found for path. 07:23.430 --> 07:32.730 So if we go ahead and look at this listing, we see it says one shared path. 07:33.570 --> 07:48.930 So the regex match of path or number space path is going to fail on this example because well, it's 07:48.930 --> 07:51.120 looking for a number and a path. 07:52.320 --> 07:57.630 And well, you can make it into an optional word instead. 07:57.960 --> 08:01.710 Let's try and copy this. 08:06.150 --> 08:06.950 Let's see. 08:06.960 --> 08:07.680 Let's see. 08:12.140 --> 08:13.700 Am I getting it all? 08:13.700 --> 08:15.530 Is this all of it? 08:19.560 --> 08:20.340 Let's see. 08:21.210 --> 08:23.880 It looks like it's missing the values we want. 08:23.910 --> 08:25.440 I can't really see those. 08:31.950 --> 08:32.160 Yeah. 08:32.160 --> 08:32.460 Okay. 08:32.460 --> 08:33.270 It's up here. 08:34.750 --> 08:37.150 So, uh, let me see. 08:39.310 --> 08:41.650 So we have baths, right? 08:42.070 --> 08:47.590 And that did not match or does not match this one. 08:47.590 --> 08:49.630 So maybe if we put in. 08:50.460 --> 08:52.530 Bath as an optional word. 08:52.830 --> 08:54.030 It can work. 08:54.030 --> 08:59.160 So I put the word in parenthesis and a question mark after. 09:00.960 --> 09:02.600 Let's see if it's still the text. 09:02.610 --> 09:03.350 One bath. 09:03.360 --> 09:04.530 It doesn't. 09:05.160 --> 09:07.830 Maybe if I have question mark before. 09:10.640 --> 09:11.660 Uh, come on, Christian. 09:11.660 --> 09:12.020 Mark. 09:12.170 --> 09:12.950 After. 09:16.070 --> 09:19.640 Oh yeah, that's because I have a space in front. 09:19.640 --> 09:21.320 So there's like two spaces. 09:21.320 --> 09:26.090 So if I put space here instead, it's going to detect both of them. 09:26.360 --> 09:34.700 And now we're kind of getting into a, I would say, advanced of, of, of course regular expressions 09:34.700 --> 09:41.780 can be a lot worse than this, but, um, we're, we're getting a little into regular expressions now 09:41.900 --> 09:51.530 and there's, there's other examples that you're going to run into where your regular expression will 09:51.530 --> 09:53.510 fail in these cases. 09:55.130 --> 09:58.970 So some of the rooms also just have studio. 09:59.000 --> 10:00.440 It just says studio here. 10:00.440 --> 10:05.000 So we could also make a or clause for studio here. 10:06.080 --> 10:13.310 However, I think that I don't want to make this into a regular expression course and go into that much 10:13.310 --> 10:13.870 detail. 10:13.880 --> 10:19.490 I think you guys by now are getting the point of how this works. 10:20.180 --> 10:25.310 So guys, this concludes the section on puppeteer scraping. 10:25.460 --> 10:33.080 There's a lot more functions inside of Puppeteer, but I think we covered the most important things, 10:33.080 --> 10:43.460 which is sort of getting the page and and parsing the HTML, the markup so we can get it. 10:43.610 --> 10:50.630 Obviously the the most important feature of these browser automation automation frameworks that you 10:50.630 --> 10:57.960 got like Nightmare JS and Puppeteer is that it's going to render the JavaScript so pages that we normally 10:57.960 --> 11:01.680 can't see, like Airbnb is now visible to us.
