I am probably missing something trivial, but I am completely baffled by the
use of namespaces when using xpath with lxml.
I have a template that creates a tree from an XML document and passes it to a
function for processing at the w level. If I change the root element of a TEI
document into ABC (turning it into a generic XML document),the following code
works:
for w in tree.xpath('//w'):
print(etree.tostring(w))
This shouldn't work in a TEI document, because the xpath method requires a
qualified name or namespace.
I assumed that the full tag name {http://www.tei-c.org/ns/1.0} might work:
for w in tree.xpath('http://www.tei-c.org/ns/1.0}w'):
print(etree.tostring(w))
But it doesn't work. Neither does a special xmlns:tei declaration.
So I am totally baffled. For ordinary lxml processing the ordinary mapping of
the URI to tei would work. But it fails for xpath. The rather terse lxml manual
was no help.
I'll be grateful for any help.
