Is there an easy way to tak a snippet of xhtml and insert it into a document, for example:
<p>test <b>paragraph</b>.</p><table><tr><td>hi</td><td>bye</td></tr></table>
I need to take little chunks of html and add them with headings into a word document.
Ive started by trying to load the html snippette into a Document, but I am getting a strange exception:
InputStream stream = new StringInputStream("<html><body><p>abc <i>def</i>.</p></body></html>");
Document hdoc = new Document(stream);
The exception is:
java.io.IOException: Problem exporting word document: The document appears to be corrupted and cannot be loaded.
The documentation implies that the Document(InputStream stream) creation method supports auto detecting the document format. Does it not support HTML?
I also tried the following as per this documentation, but it creates the same exception:
InputStream stream = new StringInputStream("<html><body><p>abc <i>def</i>.</p></body></html>");
Document hdoc = new Document(stream, "http://localhost/");
Hi
Thanks for your request. you can use DocumentBuilder.insertHtml method to achieve this. Please see the following link for more information:
https://reference.aspose.com/words/java/com.aspose.words/documentbuilder/#insertHtml-java.lang.String
To load HTML strings try using the following code:
String html = "<html><body><p>abc <i>def</i>.</p></body></html>";
InputStream stream = new ByteArrayInputStream(html.getBytes("UTF-8"));
Document doc = new Document(stream);
doc.save("C:\\temp\\out.doc");
Best regards.
It seems that your example does work when it is run from a simple java test class like what is below, but it fails when it is executed in a servlet under a Tomcat application server, still trying to track down why!
From in a servlet it fails in both the 3.3 version of the JAR and the 4.0 version as well.
public class Test4 {
public static void main(String[] args) {
try {
String html = "<html><body><p>abc <i>def</i>.</p></body></html>";
InputStream stream = new ByteArrayInputStream(html.getBytes("UTF-8"));
Document doc = new Document(stream);
} catch (Exception e) {
e.printStackTrace();
}
}
}
The idea about using the DocumentBuilder.insertHtml sounds good however I am not quite sure how to use this when my current code is using the basic Document class to build the document. Is threre a way to ‘switch’ to the DocumentBuilder to use the insertHtml method, then switch back to the normal Document class?
Currently the method called by the servlet looks like this:
public Document export(dao.Document policy) throws Exception {
List<dao.Section> sections = DAOFactory.getSectionFactory().getByDocumentId(policy.getId(),0,500);
SectionsHelper.sort(sections);
Document doc = new Document();
doc.removeAllChildren();
formatStyles(doc);
Section section = new Section(doc);
doc.appendChild(section);
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.A4);
Body body = new Body(doc);
section.appendChild(body);
addHeading(doc,body,"Heading 1", policy.getName()+" ("+policy.getNumber()+")");
for(dao.Section documentSection : sections) {
addHeading(doc,body,"Heading");
String html = "<html><body><p>abc <i>def</i>.</p></body></html>";
InputStream stream = new ByteArrayInputStream(html.getBytes("UTF-8"));
Document hdoc = new Document(stream);
// Now try to insert hdoc into the main doc
}
return doc;
}
Hi
Thank you for additional information. Actually, you can use DocumentBuilder class to build whole document. I think, this would be easier than building document using DOM.
For instance, you can try using the following code:
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Specify page setup
builder.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
builder.getPageSetup().setPaperSize(PaperSize.A4);
// insert headings
builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.HEADING_1);
builder.writeln("This is my heading");
// Insert some HTML
String html = "<html><body><p>abc <i>def</i>.</p></body></html>";
builder.insertHtml(html);
Please see the following link to learn more about DocumentBuilder:

Hi Alexey, thanks for the pointers, however I have already written a few thousand lines of code that generate my document without using DocumentBuilder, I am not quite sure how I would use document builder at the same time as using the basic Document class.
If necessary I will re-write the code to use the document builder, but it would save quite a few hours if I could work out how to setup a html document and just insert that.
Hi Jacob,
Thank you for additional information. I think, there is two ways you can achieve what you need:
Best regards.
