Get the xpath expression of a node element

[Luis Miguel Morillas]

Do the amara nodes have a method to get the xpath route from the root
of the xml document?

Sorry, somehow I missed this. There is:

amara.lib.xpath.util.abspath

I think I had planned to update it in some way, but I think it works for the most part.

Yes, it's working for me. I wrote a discover funcion to help users to
extract xpath expressions that finds some text in web pages, so our
system can learn to find info in similar pages.


def discover_path(text, node):
''' Discover best xpaths to extract text.

I.e. it can find 'Hello, World' in these cases:
<h1>Hello, World</h1>
<p>Hello, <span>World</span></p>
'''
paths = []
if text in U(node):
if hasattr(node, 'xml_children'):
for child in node.xml_children:
path = discover_path(text, child)
if path:
paths.extend(path)
if not paths: # no more specific path in childs
paths.append(util.abspath(node))
return paths
