elementtree

I asked about using BeautifulSoup to parse a very large (270MB) HTML file and getting a memory error andwas pointed toward ElementTree as a solution. I was trying to use their event-driven parsing, documented here . Testing it with the smaller settings file worked fine: >>> settings = open('S:\\Documents\\FacebookData\\html\\settings.htm') >>> for event, element in ET.iterparse(settings, events=("start", "end")): print("%5s, %4s, %s" % (event, element.tag, element.text)) Successfully prints out the elements. However, using that same code with 'messages.htm' instead of 'settings.htm' just to

I'm trying to parse an XML document with a default namespace, i.e. the root node has an xmlns attribute. This is annoying if you want to try find certain tags in the child nodes because each tag is prefixed with the default namespace. xml.etree.ElementTree.findall() allows for a namespaces dictionary to be passed in but I can't seem to find what the default namespace is mapped to. I have tried using 'default', None, 'xmlns' with no success. One option that does seem to work is to prefix the tag passed to findall() with 'xmlns:' (EDIT: this can be any arbitrary unique name actually) and a

I'm trying to do XML validation against some XSD in python. I was successful using lxml package. But the problem starts when I tried to port my code into python 3.4. I tried to install lxml for 3.4 version. Looks like my enterprise linux doesn't play very well with lxml. pip installation: pip install lxml Collecting lxml Downloading lxml-3.4.4.tar.gz (3.5MB) 100% |################################| 3.5MB 92kB/s Installing collected packages: lxml Running setup.py install for lxml Successfully installed lxml-3.4.4 After pip Installation : > python Python 3.4.1 (default, Nov 12 2014, 13:34:29)

I've used Element Tree for a while and i love it because of its simplicity But I'm doubting of its implementation of x path This is the XML file <a> <b name="b1"></b> <b name="b2"><c/></b> <b name="b2"></b> <b name="b3"></b> </a> The python code import xml.etree.ElementTree as ET tree = ET.parse('test.xml') root = tree.getroot() root.findall("b[@name='b2' and c]") The program shows the error: invalid predicate But if I use root.findall("b[@name='b2']") or root.findall("b[c]") It works, ElementTree provides limited support for XPath expressions. The goal is to support a small subset of the

My question follows on from another stackoverflow question:- "How to get the root node of an xml file in Python?" from xml.etree import ElementTree as ET path = 'C:\cool.xml' et = ET.parse ( path ) root = et.getroot() When I extract and print the root tag, I receive:- <Element 'root' at 0x1234abcd> I then want to check that the root tag has a certain title, how do I pull out just the tag name? If I try: if root == "root": print 'something' it doesn't work, so I assume I need to convert 'root' to text or something like that? I am very new to Python. root is an instance of the Element class.
