And another question, which is rather Silverlight then IronPython related. I
hope it's okey to ask it here.
How should I create a TextNode from Silverlight with IronPython code? In
javascript, one would:

node = document.createTextNode("text");

According to the MSDN documentation, the HtmlDocument class doesn't have a
createTextNode, and I can't find it anywhere else. Michael his book has been
extremely useful for me, but he uses innerHtml which i really don't like.
InnerHtml is is an old-style method for DOM-manipulation, and unsafe by
definition. (it allows you to insert HTML code)

So far, I worked around my previous problem by using the NextNode property,
which works fine. Though not as nice as iterators would be:

def insert_rows(rows):
        html_table =
        row = XDocument.Parse(rows).Element('table').Element('row')

        while row != None:
                html_row = HtmlPage.Document.CreateElement('tr')
                field = row.Element('field')

                 while field != None:
                        html_field = HtmlPage.Document.CreateElement('td')

#html_field.Children.Add(HtmlPage.Document.CreateTextNode(field.Value)) #
Doesn't exist??

                        field = field.NextNode

                row = row.NextNode

Thank you
