[lxml-dev] Proper syntax to insert elements with namespaces?

[Mike MacCana]

Hello all,

I'm reading some OpenDocument files with lxml, and inserting various
elements. A snippet, which works fine, is below. Yay LXML!


## Parse our content as 'document'
document = etree.parse(contentfile)
print etree.tostring(document.getroot(), pretty_print=True),

## The body of the document, where we'll add our text elements
body = document.xpath('/office:document-content/office:body/office:text', namespaces={'office':'urn:oasis:names:tc:opendocument:xmlns:office:1.0','text':'urn:oasis:names:tc:opendocument:xmlns:text:1.0'})

## Insert some text as element one
print "adding element:"
body[0].insert(1, etree.Element("text",name="Standard"))

## Identify the element by it's xpath and change its contents.
newelement = document.xpath('/office:document-content/office:body/office:text/text', namespaces={'office':'urn:oasis:names:tc:opendocument:xmlns:office:1.0','text':'urn:oasis:names:tc:opendocument:xmlns:text:1.0'})
newelement[0].text="new element text"


1. Is there a better way to refer to, and set the text of, the newly
created element?
2. How do I insert an element with a namespace? The code above creates:


      <text name="Standard">new element text</text>


But I'd prefer: 


      <text:p text:style-name="Standard">old element</text:p>



Cheers,

Mike
