You can install the current developer version of ET 1.3 from here: http://svn.effbot.org/public/elementtree-1.3 Or use lxml, which comes with full-fledged XPath support. http://codespeak.net/lxml > The following code is as > close as I can get to what I want, but it doesn't run because I've > attempted to use v1.3 syntax, ended up writing complete crap instead, > and I can't understand the docs well enough for the v1.2.7 syntax. > Perhaps someone can understand what I mean and give me a clue as to how > to write this? > > from elementtree.ElementTree import ElementTree > > tree = ElementTree(file='test.kml') > kml = tree.getroot() > ns = 'http://earth.google.com/kml/2.1' > for folders in kml.findall("{%s}Folder/{%s}Folder" % (ns, ns)): > if folders["name"].text=='Routes': > print folder.findall("{%s}LineString/{%s}coordinates" % (ns, > ns)) What's "name" here? An attribute? Then this might work better: if folders.get("name") == 'Routes': or did you mean it to be a child node? if folders.findtext("name") == 'Routes': Stefan -- http://mail.python.org/mailman/listinfo/python-list
