How to avoid surrounding html head tags in Jsoup parse
Using Jsoup i try to parse the given html content. After Jsoup.parse() the html output append html, head and body tag to the input. I just want to ignore these.
Sample Input:
<p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>
Java code:
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
public class HTMLParse {
public static void main(String args[]) throws IOException {
try{
File input = new File("/ab.html");
String html = FileUtils.readFileToString(input, null);
Document doc = Jsoup.parseBodyFragment(html);
doc.outputSettings().prettyPrint(false);
System.out.println(doc.html());
}
catch(Exception e){
e.printStackTrace();
}
}
}
Actual output:
<html><head></head><body><p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>
</body></html>
Expected Output:
<p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>
Please help.
Answer
The cause:
parseBodyFragment() as well as all other parse()-methods use a HTML parser by default. And those add always the HTML-Shell (<html>…</html>, <head>…</head> etc.).
The Solution:
Just don't use a HTML-parser, use a XML-parser instead ;-)
Document doc = Jsoup.parse(html, "", Parser.xmlParser());
Replace that single line and your problem is solved.
Example:
final String html = "<p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>";
Document docHtml = Jsoup.parse(html);
Document docXml = Jsoup.parse(html, "", Parser.xmlParser());
System.out.println("******* HTML *******\n" + docHtml);
System.out.println();
System.out.println("******* XML *******\n" + docXml);
Output:
******* HTML *******
<html>
<head></head>
<body>
<p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>
</body>
</html>
******* XML *******
<p><b>This <i>is</i></b> <i>my sentence</i> of text.</p>
