Hi @Vani1012 ,
Sure, I can help you with a Java program to identify pages with English content. Here’s how you can do it:
- Crawl the Directory: Fetch all pages under the specified directory.
- Fetch Page Content: For each URL, download the HTML content.
- Language Detection: Analyze the text content of each page to determine its language.
- List English Pages: Compile a list of pages where English content is detected.
Below is a Java program that demonstrates this approach:
Java Program
Step 1: Add Dependencies
You'll need the following libraries:
- jsoup for HTML parsing
- apache-lucene for language detection
Add these dependencies to your pom.xml if you're using Maven:
<dependencies>
<dependency>
<groupId>org.jsoup</groupId>
<artifactId>jsoup</artifactId>
<version>1.14.3</version>
</dependency>
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-langdetect</artifactId>
<version>2.1.0</version>
</dependency>
</dependencies>
Step 2: Java Code
Here's the Java code to fetch pages, detect the language, and list pages with English content:
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import org.apache.tika.language.detect.LanguageDetector;
import org.apache.tika.language.detect.LanguageResult;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class EnglishContentDetector {
public static void main(String[] args) throws IOException {
String baseUrl = "https://www.example.com";
List<String> urls = List.of(
"/content/products/zh-cn/construction-equipment/service/parts-and-service-for-cobra-petrol-breakers/rodsandbits",
"/content/products/zh-cn/construction-equipment/service/parts-and-service-for-pneumatic-rock-drills/rodsandbits"
// Add more URLs as needed
);
List<String> englishPages = new ArrayList<>();
LanguageDetector detector = LanguageDetector.getDefaultLanguageDetector().loadModels();
for (String url : urls) {
String fullUrl = baseUrl + url;
Document doc = Jsoup.connect(fullUrl).get();
String text = doc.body().text();
LanguageResult result = detector.detect(text);
if ("en".equals(result.getLanguage())) {
englishPages.add(fullUrl);
}
}
System.out.println("Pages with English content:");
for (String page : englishPages) {
System.out.println(page);
}
}
}
Explanation
- Dependencies: We use jsoup for fetching and parsing HTML content and apache-tika for language detection.
- Fetching URLs: The list urls should contain all URLs under the specified directory. This list can be populated using a web crawler or manually.
- Fetching Content: We send an HTTP GET request to each URL to fetch its content using Jsoup.connect(fullUrl).get().
- Language Detection: We use Apache Tika’s LanguageDetector to detect the language of the text content.
- Listing English Pages: If a page is detected to have English content, its URL is added to the englishPages list.
notes:
- Replace https://www.example.com with the actual base URL of your website.
- Ensure you have permission to crawl the website.
- Adjust the list of urls to include all pages under the specified directory.
This approach should help you identify pages with English content in the specified directory.
