$ b这是我的代码转换HTML到PDF。我能够转换它，但在PDF文件中，它保存为整个HTML，而我只需要显示文本。 < HTML><身体GT;这是我的项目< / body>< / html> 获取保存到PDF，而它应该只保存这是我的项目您可以使用 text / html / simpleparser / HTMLWorker.htmlrel =nofollow noreferrer> HTMLWorker class（deprecated）like this： import com.itextpdf.text.html.simpleparser.HTMLWorker;
// ...
try {
String k =< html>< body>这是我的项目< / body>< / html>;
OutputStream file = new FileOutputStream（new File（C：\\Test.pdf））;
Document document = new Document（）;
PdfWriter.getInstance（document，file）;
document.open（）;
HTMLWorker htmlWorker = new HTMLWorker（document）;
htmlWorker.parse（new StringReader（k））;
document.close（）;
file.close（）;
} catch（Exception e）{
e.printStackTrace（）;
}
或使用 XMLWorker ，（从 this jar ）： com.itextpdf.tool.xml.XMLWorkerHelper;
// ...
try {
String k =< html>< body>这是我的项目< / body>< / html>;
OutputStream file = new FileOutputStream（new File（C：\\Test.pdf））;
Document document = new Document（）;
PdfWriter writer = PdfWriter.getInstance（document，file）;
document.open（）;
InputStream is = new ByteArrayInputStream（k.getBytes（））;
XMLWorkerHelper.getInstance（）。parseXHtml（writer，document，is）;
document.close（）;
file.close（）;
} catch（Exception e）{
e.printStackTrace（）;

This is my code to convert HTML to PDF. I am able to convert it but in PDF file it saves as whole HTML while I need to display only text. <html><body> This is my Project </body></html> gets saved to PDF while it should save only This is my Project.
You can do it with the HTMLWorker class (deprecated) like this:
import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
String k = "<html><body> This is my Project </body></html>";
OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
Document document = new Document();
PdfWriter.getInstance(document, file);
document.open();
HTMLWorker htmlWorker = new HTMLWorker(document);
htmlWorker.parse(new StringReader(k));
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
}
or using the XMLWorker, (download from this jar) using this code:
import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
String k = "<html><body> This is my Project </body></html>";
OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
InputStream is = new ByteArrayInputStream(k.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
file.close();
} catch (Exception e) {
e.printStackTrace();
}
