Scraping an Online Movie Website
Let’s start another example from a real world website. We'll choose to scrape a movie website.
Let’s add a new class and name it “MovieScraper”:
Now let’s take a look on the site that we will scrape:
This is part of the homepage HTML we see on the website:
<div id="movie-featured" class="movies-list movies-list-full tab-pane in fade active">
<div data-movie-id="20746" class="ml-item">

As we can see, we have a movie ID, Title, and Link to Detailed Page.
Let’s start to scrape this set of data:
public class MovieScraper : WebScraper
{
public override void Init()
{
License.LicenseKey = "LicenseKey";
this.LoggingLevel = WebScraper.LogLevel.All;
this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
this.Request("www.website.com", Parse);
}
public override void Parse(Response response)
{
foreach (var Divs in response.Css("#movie-featured > div"))
{
if (Divs.Attributes ["class"] != "clearfix")
{
var MovieId = Divs.GetAttribute("data-movie-id");
var link = Divs.Css("a")[0];
var MovieTitle = link.TextContentClean;
Scrape(new ScrapedData() { { "MovieId", MovieId }, { "MovieTitle", MovieTitle } }, "Movie.Jsonl");
}
}
}
}
public class MovieScraper : WebScraper
{
public override void Init()
{
License.LicenseKey = "LicenseKey";
this.LoggingLevel = WebScraper.LogLevel.All;
this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
this.Request("www.website.com", Parse);
}
public override void Parse(Response response)
{
foreach (var Divs in response.Css("#movie-featured > div"))
{
if (Divs.Attributes ["class"] != "clearfix")
{
var MovieId = Divs.GetAttribute("data-movie-id");
var link = Divs.Css("a")[0];
var MovieTitle = link.TextContentClean;
Scrape(new ScrapedData() { { "MovieId", MovieId }, { "MovieTitle", MovieTitle } }, "Movie.Jsonl");
}
}
}
}
Public Class MovieScraper
Inherits WebScraper
Public Overrides Sub Init()
License.LicenseKey = "LicenseKey"
Me.LoggingLevel = WebScraper.LogLevel.All
Me.WorkingDirectory = AppSetting.GetAppRoot() & "\MovieSample\Output\"
Me.Request("www.website.com", AddressOf Parse)
End Sub
Public Overrides Sub Parse(ByVal response As Response)
For Each Divs In response.Css("#movie-featured > div")
If Divs.Attributes ("class") <> "clearfix" Then
Dim MovieId = Divs.GetAttribute("data-movie-id")
Dim link = Divs.Css("a")(0)
Dim MovieTitle = link.TextContentClean
Scrape(New ScrapedData() From {
{ "MovieId", MovieId },
{ "MovieTitle", MovieTitle }
},
"Movie.Jsonl")
End If
Next Divs
End Sub
End Class
What’s new in this code?
The Working Directory property is used to set the main working directory for all scraped data and its related files.
Let's do more.
What if we need to build typed objects that will hold scraped data in formatted objects?
Let’s implement a movie class that will hold our formatted data:
public class Movie
{
public int Id { get; set; }
public string Title { get; set; }
public string URL { get; set; }
}
public class Movie
{
public int Id { get; set; }
public string Title { get; set; }
public string URL { get; set; }
}
Public Class Movie
Public Property Id() As Integer
Public Property Title() As String
Public Property URL() As String
End Class
Now we will update our code:
public class MovieScraper : WebScraper
{
public override void Init()
{
License.LicenseKey = "LicenseKey";
this.LoggingLevel = WebScraper.LogLevel.All;
this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
this.Request("https://website.com/", Parse);
}
public override void Parse(Response response)
{
foreach (var Divs in response.Css("#movie-featured > div"))
{
if (Divs.Attributes ["class"] != "clearfix")
{
var movie = new Movie();
movie.Id = Convert.ToInt32( Divs.GetAttribute("data-movie-id"));
var link = Divs.Css("a")[0];
movie.Title = link.TextContentClean;
movie.URL = link.Attributes ["href"];
Scrape(movie, "Movie.Jsonl");
}
}
}
}
public class MovieScraper : WebScraper
{
public override void Init()
{
License.LicenseKey = "LicenseKey";
this.LoggingLevel = WebScraper.LogLevel.All;
this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
this.Request("https://website.com/", Parse);
}
public override void Parse(Response response)
{
foreach (var Divs in response.Css("#movie-featured > div"))
{
if (Divs.Attributes ["class"] != "clearfix")
{
var movie = new Movie();
movie.Id = Convert.ToInt32( Divs.GetAttribute("data-movie-id"));
var link = Divs.Css("a")[0];
movie.Title = link.TextContentClean;
movie.URL = link.Attributes ["href"];
Scrape(movie, "Movie.Jsonl");
}
}
}
}
Public Class MovieScraper
Inherits WebScraper
Public Overrides Sub Init()
License.LicenseKey = "LicenseKey"
Me.LoggingLevel = WebScraper.LogLevel.All
Me.WorkingDirectory = AppSetting.GetAppRoot() & "\MovieSample\Output\"
Me.Request("https://website.com/", AddressOf Parse)
End Sub
Public Overrides Sub Parse(ByVal response As Response)
For Each Divs In response.Css("#movie-featured > div")
If Divs.Attributes ("class") <> "clearfix" Then
Dim movie As New Movie()
movie.Id = Convert.ToInt32(Divs.GetAttribute("data-movie-id"))
Dim link = Divs.Css("a")(0)
movie.Title = link.TextContentClean
movie.URL = link.Attributes ("href")
Scrape(movie, "Movie.Jsonl")
End If
Next Divs
End Sub
End Class
What’s new?
- We implement Movie Class to hold our scraped data
- We pass movie objects to the Scrape Method and it understands our format and saves in a defined format as we can see here:
Let’s start scraping a more detailed page.
The Movie Page looks like this:
<div class="mvi-content">
<div class="thumb mvic-thumb"
style="background-image: url(https://img.gocdn.online/2017/04/28/poster/5a08e94ba02118f22dc30f298c603210-guardians-of-the-galaxy-vol-2.jpg);"></div>
<div class="mvic-desc">

We can extend our movie class with new properties (Description, Genre, Actor, Director, Country, Duration, IMDB Score) but we’ll use (Description, Genre, Actor) only for our sample.
public class Movie
{
public int Id { get; set; }
public string Title { get; set; }
public string URL { get; set; }
public string Description { get; set; }
public List<string> Genre { get; set; }
public List<string> Actor { get; set; }
}
public class Movie
{
public int Id { get; set; }
public string Title { get; set; }
public string URL { get; set; }
public string Description { get; set; }
public List<string> Genre { get; set; }
public List<string> Actor { get; set; }
}
Public Class Movie
Public Property Id() As Integer
Public Property Title() As String
Public Property URL() As String
Public Property Description() As String
Public Property Genre() As List(Of String)
Public Property Actor() As List(Of String)
End Class
Now we’ll navigate to the Detailed page to scrape it.
IronWebScraper enables you to add more to the scrape function to scrape different types of page formats
As we can see here:
public class MovieScraper : WebScraper

What’s new?
- We can add scrape functions (ParseDetails) to scrape detailed pages
- We moved the Scrape function that generates our file to the new function
- We used the IronWebScraper feature (MetaData) to pass our movie object to the new scrape function
- We scraped the page and saved our movie object data to a file
