<?xml version="1.0" ?> <root> <element> Some text here </element> </root>
E
Implementation: E-on-Java
This makes use of XML libraries provided with Java.
def document := <unsafe:javax.xml.parsers.makeDocumentBuilderFactory> \ .newInstance() \ .newDocumentBuilder() \ .getDOMImplementation() \ .createDocument(null, "root", null) def root := document.getDocumentElement() root.appendChild( def element := document.createElement("element")) element.appendChild( document.createTextNode("Some text here")) println(document.saveXML(root))
(On the use of <unsafe>
: The class has not yet been reviewed for E safety, so <import:...makeDocumentBuilderFactory>
is not yet allowed. The review would probably be straightforward.)

DOM
var doc = document.implementation.createDocument( null, 'root', null ); var root = doc.documentElement; var element = doc.createElement( 'element' ); root.appendChild( element ); element.appendChild( document.createTextNode('Some text here') ); var xmlString = new XMLSerializer().serializeToString( doc );
E4X
var xml = <root> <element>Some text here</element> </root>; var xmlString = xml.toXMLString();
E4X — with processing instruction
XML.ignoreProcessingInstructions = false; var xml = <?xml version="1.0"?> <root> <element>Some text here</element> </root>; var xmlString = xml.toXMLString();
Perl
use XML::DOM::BagOfTricks qw(createDocument createTextElement); my ($doc, $root) = createDocument('root'); $root->appendChild( createTextElement($doc, 'element', 'Some text here') ); print $doc->toString;
PHP
Interpreter: PHP 5
<?php $dom = new DOMDocument();//the constructor also takes the version and char-encoding as it's two respective parameters $dom->formatOutput = true;//format the outputted xml $root = $dom->createElement('root'); $element = $dom->createElement('element'); $element->appendChild($dom->createTextNode('Some text here')); $root->appendChild($element); $dom->appendChild($root); $xmlstring = $dom->saveXML();
Python
Interpreter: Python 2.5
from xml.dom.minidom import getDOMImplementation dom = getDOMImplementation() document = dom.createDocument(None, "root", None) topElement = document.documentElement firstElement = document.createElement("element") topElement.appendChild(firstElement) textNode = document.createTextNode("Some text here") firstElement.appendChild(textNode) xmlString = document.toprettyxml(" " * 4)
Interpreter: Python 2.5
from xml.etree import ElementTree as et root = et.Element("root") et.SubElement(root, "element").text = "Some text here" xmlString = et.tostring(root)
Ruby
require("rexml/document") include REXML (xml = Document.new) << XMLDecl.new root=xml.add_element('root') element=root.add_element('element') element.add_text('Some text here') puts xml.to_s(0)
