How to remove encoding=“UTF-8” standalone=“no” fro

问题:

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!

回答1:

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.

回答2:

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

doc.setXmlStandalone(true);

will erase standalone="no"

回答3:

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

This would resolve your issue, verified at JDK 6
