python - How do I query in ElementTree as in Xpath? -

this sample query might in php:

foreach(steps step) { aret_eles = xpath->query(t_elequery, step) }

now in python:

for step in index steps: aret_eles = ?!?!?!?!!??!?!!??!!

i tried this:

for step in index steps: aret_eles = xpath.query(t_elequery, step)

it didn't work. i've imported elementtree xml.etree.elementtree, though.

the official page able find on xpath in elementtree didn't have documentation or examples.... , know how horribly bad python official's tutorials are. so, i'm looking resource.

if have lxml, high-performance, full-featured version of elementtree, installed can utilize xpath follows:

>>> lxml import etree >>> xml = """<ham><spam>hello!</spam> <spam>goodbye!</spam></ham>""" >>> tree.xpath("//spam/text()") ['hello!', 'goodbye!']

i can recommend lxml python xml needs; it's fast , pythonic.
