First of all:
Ok, so I have such piece of code:
val text = new scala.xml.Text("just a text")
val root = new scala.xml.Elem(null,"element",null,scala.xml.TopScope,text)
val doc = new scala.xml.Document()
doc.docElem = root
println(doc.toString())
Almost good but as result I get:
<element>just a text</element>
and I would like to get XML header too, like:
<?xml version="1.0"?>
<element>just a text</element>
Question: How to add it?
Of course in common-sense way, not some hacking with extra verbatim println with header ;-).

Scala treats XML as the first-class citizen. So, instead of embedding XML documents into strings. , you can place them inline in your code like you place an int or double value. For example. scala> val xml = Hello. xml: scala.xml.Elem = Hello.
Everything in an XML document is a node. For example, the entire document is the document node, and every element is an element node. Root node. The topmost node of a tree. In the case of XML documents, it is always the document node, and not the top-most element.
All XML documents must contain a single tag pair to define a root element. All other elements must be within this root element. All elements can have sub elements (child elements). Sub elements must be correctly nested within their parent element.
What is XML Used For? XML is one of the most widely-used formats for sharing structured information today: between programs, between people, between computers and people, both locally and across networks. If you are already familiar with HTML, you can see that XML is very similar.
The only solution I've found is to add the following code
val writer : PrintWriter = new PrintWriter(System.out)
XML.write(writer,root,"utf-8",true,null)
writer.flush()
