java - 将范围报告 HTML 文件转换为 PDF

Question

我正在尝试将范围报告 HTML 文件转换为 PDF，但是我没有成功。

下面是我试过的代码。

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;

public class Demo 
{
public static void main( String[] args ) throws DocumentException,     IOException
{
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("pdf.pdf"));
document.open();
XMLWorkerHelper.getInstance().parseXHtml(writer, document,new FileInputStream("html.html")); 
document.close();
System.out.println( "PDF Created!" );
}
}

Exception in thread "main" com.itextpdf.tool.xml.exceptions.RuntimeWorkerException: Invalid nested tag head found, expected closing tag link.

试试这个例子。您没有创建文件并尝试填充它。

package sandbox.xmlworker;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import sandbox.WrapToTest;

@WrapToTest
public class D02_ParseHtml {

    public static final String HTML = "resources/xml/walden.html";
    public static final String DEST = "results/xmlworker/walden1.pdf";

    /**
     * Html to pdf conversion example.
     * @param file
     * @throws IOException
     * @throws DocumentException
     */
    public void createPdf(String file) throws IOException, DocumentException {
        // step 1
        Document document = new Document();
        // step 2
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
        // step 3
        document.open();
        // step 4
        XMLWorkerHelper.getInstance().parseXHtml(writer, document,
                new FileInputStream(HTML));
        // step 5
        document.close();
    }

    /**
     * Main method
     */
    public static void main(String[] args) throws IOException, DocumentException {
        File file = new File(DEST);
        file.getParentFile().mkdirs();
        new D02_ParseHtml().createPdf(DEST);
    }
}
