Generating XML with Newspeak

While experimenting with Newspeak I wrote a small utility class for generating basic XML documents.

An example of its use looks like this:

w:: getTestingWriter: output .
w element: 'foo'
attributes: { {'id'. 'goo'.} }
with: [
w element: 'foo1'.
w element: 'foo2'.
w element: 'foo3'
with: [
w element: 'foo4'
with: [
w text: 'Hello'.
].
w cdata: ''.
].
].


This generates:

<foo id="goo"><foo1 /><foo2 /><foo3><foo4>Hello</foo4><![CDATA[<loo>]]></foo3></foo>


The code for generating XML this way is based on a previous experiment of using Python's 'with' statement to wrap the .NET's System.Xml.XmlWriter class to generate XML.

Code for this post can be found here.

does newspeak have method-missing support ? check out ruby's builder for a more compact syntax through method-missing http://builder.rubyforge.org/
