XML/DOM serialization: Difference between revisions

=={{header|Wren}}==

Wren has no built-in or (AFAIK) third party support for XML so we code a minimal DOM sufficient for completing this task.

<lang ecmascript>class XmlDocument {

construct new(root) {

_root = root

}

toString { "<?xml version=\"1.0\" ?>\n%(_root.toString(0))" }

}

class XmlElement {

construct new(name, text) {

_name = name

_text = text

_children = []

}

name { _name }

text { _text }

children { _children }

addChild(child) { _children.add(child) }

toString(level) {

var indent = " "

var s = indent * level + "<%(name)>\n"

if (_text != "") s = s + indent * (level + 1) + _text + "\n"

for (c in _children) {

s = s + c.toString(level+1) + "\n"

}

return s + indent * level + "</%(name)>"

}

}

var root = XmlElement.new("root", "")

var child = XmlElement.new("element", "Some text here")

root.addChild(child)

var doc = XmlDocument.new(root)

System.print(doc)</lang>

{{out}}

<pre>

<?xml version="1.0" ?>

<root>

<element>

Some text here

</element>

</root>

</pre>
