Remove "standalone" attribute from from XML declaration

843834Dec 14 2009 — edited Dec 18 2009

Hi everybody,
I am modifying an xml file and when I'm saving it standalone attribute apears in xml declaration.
The original xml has the declaration like this:

<?xml version="1.0" encoding="UTF-8"?>

The new xml declaration is:

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

Java code looks like this:

    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty(OutputKeys.METHOD,"xml");
    StreamResult output = new StreamResult(new FileWriter(file));
    DOMSource source = new DOMSource(workDocument);
    transformer.transform(source, output);
    output.getWriter().flush();
    output.getWriter().close();

I am using Java 1.6.0.13
Is there any way to remove standalone attribute?

I think the API allows you to specify whether you want standalone="yes" or standalone="no", see [http://java.sun.com/javase/6/docs/api/javax/xml/transform/OutputKeys.html#STANDALONE|http://java.sun.com/javase/6/docs/api/javax/xml/transform/OutputKeys.html#STANDALONE] but I am not aware of a way to ensure that no standalone pseudo attribute is output.

Is there any way to remove standalone attribute?

Why do you need to do that?

The XML document I'm editing is part of another application and the other XML documents doesn't have "standalone" attribute in XML declaration.

Thanks a lot. I read the documentation already. The default output (when not specified in OutputKeys properties) is standalone="no".

Well, from my point of view this should not be a problem but theese XMLs I am editing are generated by some Tibco application so I do not want to change its XML definition. Anyway ... does anyone knows how to do that? I tried with 1.6 and 1.5 but no positive results.

DrClap

So it's just an aesthetic problem then? You don't actually have to deal with non-compliant parsers which can't handle that output? I don't believe you will find that Tibco specifies that the standalone pseudo-attribute has to be absent... or does it?

so, did you try specifying standalone="yes"?

DrClap

As far as I can see from the XML Recommendation, a document with standalone="no" is equivalent to a document which doesn't have a standalone attribute. So unless you're dealing with a broken parser which can't handle the standalone attribute, it's a waste of time to fuss about the existence of one.

Hi guys, I solved the problem.
There is no need to set in transformer OutputKeys.standalone property. The solution was:

workDocument.setXmlStandalone(true);

before creating the DOMSource.

EJP

Surely you mean 'false'? You said you were trying to remove it.

843834

For sure "true". If you set it "false" you cannot control it to appear or not. So setXmlStandalone(true) on Document. In transformer if you want an output use OutputKeys with whatever "yes" or "no" you need. If you setXmlStandalone(false) on Document your output will be always standalone="no" no matter what you set (if you set) in Transformer.
