I just learned Prototype for Javascript. It's super convenient: using the $ shortcut, accessing xml elements is not painful any more!
The question: is there a Prototype-like extension for Python?
Python has lxml which has the xpath
method wherein you could use xpath expressions to select elements. As I understand it, $ in prototype searches and returns an element that has a particular id, in which case could be translated in xpath to *[@id=<someid>]
like so:
>>> import lxml.etree
>>> tree = lxml.etree.XML("<root><a id='1'/><b id='2'/></root>")
>>> tree.xpath("*[@id=1]")
[<Element a at c3bc30>]
>>> lxml.etree.tostring(tree.xpath("*[@id=1]")[0])
'<a id="1"/>'
I think the Python standard library includes support for a subset of xpath in ElementTree too so you might be able to implement that there somehow if you do not wish to install lxml (which isn't included in stdlib)...
