How to remove encoding="UTF-8" standalone="no" from xml Document object in Java

Question

I want to create XML in Java.

     DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
     DocumentBuilder docBuilder;
     docBuilder = dbfac.newDocumentBuilder();
     Document doc = docBuilder.newDocument();

but Java automatically creates declaration like this

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

How can I remove encoding="UTF-8" standalone="no" so it will be

<?xml version="1.0"?>

Thanks!

@JoachimSauer, I don't want to override encoding because other program uses this XML in a way I don't know. So I can't be sure what encoding I can set — VextoR, Sep 22 '11 at 08:23
@UmerHayat, no, that question about removing ALL XML declaration — VextoR, Sep 22 '11 at 08:23
@VextoR: **Any** tool that accepts XML **must** accept one with a valid encoding property (especially if the encoding specified is UTF-8). If your other tool doesn't accept that, then it's **broken**! — Joachim Sauer, Sep 22 '11 at 08:35
The values you are trying to remove are assumed (if the parser is following the rules in the XML specification) to be the default if they aren't specified, so removing them would make no difference! — Quentin, Sep 22 '11 at 08:40
UTF-8 is the default encoding of an XML document if there is no Byte-Order-Mark (BOM): http://www.opentag.com/xfaq_enc.htm#enc_default. This means that or are equivalent declaration (without BOM). — Laurent Legrand, Sep 22 '11 at 08:44

Why do you need to remove an encoding? But..

doc.setXmlStandalone(true);

will erase standalone="no"

transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");

This would resolve your issue, verified at JDK 6

Dont understand the negative mark on the question. I had the same issue to create a BPEL file and there might be tons other reasons this is needed. So thank you for your answer. Would've taken me ages. – eskalera Jan 22 '13 at 13:30

I think there is no legal way to exclude theese attributes from generation. But after it's generated you can use XSLT to remove this.

I think this is a good way.
