Parsing XML - Newbie help

R

rh0dium

Hi all,

I am relatively new to python and certainly new to XML parsing. Can
some show me how to get the product text out of this? Really I want to
know this has 2 processors and the are AMD Opteron(tm) Processor 250

I have gotten this far...

class HWParser:

def __init__(self):
if os.path.isfile(LSHW):
lshw=Exec.Exec(LSHW)
lshw.execute('-xml')
else:
print "lshw does not exist", LSWH
return "Unknown"

self.data = lshw.read()
self.error = lshw.error()
self.exit = lshw.poll()

if self.error:
print "Error Exist", self.error
return
else:
self.xml = minidom.parseString(self.data)
self.xml.normalize()

def p (self):
print self.xml.toxml()

If anyone can help me out that would be great!

Hi
I am relatively new to python and certainly new to XML parsing.
Click to expand...

Me too. However there are plenty of good docs/tutorials available to
help with both XML and using it in Python.

For XML you may wish to look at http://www.w3schools.com/. It has a very
accessible set of tutorials on XML and related technologies, which I
find make it very quick to get up and running. For what you are trying
to do you may wish to look at XPath, or ideally XQuery although I'm not
sure there is an XQuery implementation in Python.

For Python and XML there is Mark Pilgrim's excellent chapter on Parsing
XML with xml.dom.minidom
(http://diveintopython.org/xml_processing/index.html).

The is also the PyXML project at Sourceforge
(http://pyxml.sourceforge.net/). A list of useful links is maintained
there (http://pyxml.sourceforge.net/topics/).

You may also wish to investigate resources at the Python XML SIG page
(http://www.python.org/sigs/xml-sig/).

These are just some of the sources of information I am using. Hope this
helps.

Cheers

Dan

didn't you ask the same question a few days ago? did you read the
replies to that post?

assuming that your sample is correct, you need to process the almost-
but-not-quite-XML file before passing it to an XML processor. here's an
ElementTree-based example that does that:

# see http://effbot.org/zone/element-index.htm
from elementtree import ElementTree as ET

data = open(...).read() # or os.popen(...).read()

# strip off bogus XML declaration
import re
m = re.match("<\?xml[^>]+>", data)
if m:
data = data[m.end():]

# wrap notes in container element
data = "<doc>" + data + "</doc>"

tree = ET.XML(data)

processors = []
for elem in tree.findall(".//node"):
if elem.get("class") == "processor":
processors.append(elem.findtext("product"))
print len(processors)
print processors

given your example, this prints:

2
['AMD Opteron(tm) Processor 250', 'AMD Opteron(tm) Processor 250']

Yes I did but the XML was malformed.. Actually it still is but you
helped me figure out a way to correct it - Thanks

Here is what I have so far. Now I want to find a child of a child ( I
think that's how you state it ?? ) Below is a piece of the XML which I
am trying to parse.. In short I want to figure out all of the memory
in a system. I can look at the "size" of all "bank:?"'s and add them
up. I am having trouble getting to the children of the "System Memory"

inp = open("xml.test1")
data = inp.read()
inp.close()
# strip off bogus XML declaration
import re
m = re.match("<\?xml[^>]+>", data)
if m:
data = data[m.end():]
# Apparently ampersands are common in lshw.. Get rid of them..
data = data.replace('&ampersand;', '')
# wrap notes in container element
data = "<doc>" + data + "</doc>"

tree = ET.XML(data)

for elem in tree.findall(".//node"):
if elem.get("class") == "memory":
if elem.findtext("description") == "System Memory":
print "Found system memory bank"

Ok so up to here I am ok. I find ( If you want the full xml let me
know) two blocks of system memory. It MUST be "System Memory" only.
Now how do I get a list of all of the children "nodes" of this. They
are named bank:N ( i.e bank:0, bank:1 etc [see below] ). For each one
of those there may ( or may not ) have some memory stuck in it. I can
tell if there is memory because a size is given. I want to a list of
all of the sizes. From there I can say you have sum(memory) in
len(memory) banks of total banks.

Here is what I tried - but I was clearly messing up..

for mem in elem.findall("./node/node")
if elem.get("class") == "memory":
print "Entering Memory Class"
if elem.findtext("size"):
print "Found size",
elem.findtext("size"):

And the XML which goes with that..

Thanks so much. PS - XML can be a real PITA when the data you throw at
it is not "correct". I actually had started working with sgmllib after
I saw a similar thread. However I ran into the same problem ( child of
child..)

Thanks again.

So here is what I ended up with. I would really like a XML element
tree guru to look at this. Please ensure that is makes sense.. I
really do appreciate the help! Thanks again.

inp = open("xml.test1")
data = inp.read()
inp.close()
# strip off bogus XML declaration
import re
m = re.match("<\?xml[^>]+>", data)
if m:
data = data[m.end():]
# Apparently ampersands are common in lshw.. Get rid of them..
data = data.replace('&ampersand;', '')
# wrap notes in container element
data = "<doc>" + data + "</doc>"

tree = ET.XML(data)
memory_banks = []
totalbanks = 0
processors = []; processor_vendor= []; processor_freq= []
for elem in tree.findall(".//node"):
if elem.get("class") == "system":
vendor=elem.findtext("vendor")
model=elem.findtext("product")
description=elem.findtext("description")
serial=elem.findtext("serial")
if elem.get("class") == "processor":
processors.append(elem.findtext("product"))
processor_vendor.append(elem.findtext("vendor"))
freq1=float(elem.findtext("size"))/1000000000.00
processor_freq.append(str(freq1)+"Ghz")
if elem.get("class") == "memory":
if elem.findtext("description") == "System Memory":
print "Found system memory bank"
if elem.getchildren():
#Can also use: "for child in
element.getchildren():"
for child in elem:
if child.tag == "node":
# We know the node tag has the right
children
for children in child.getchildren():
#Child element tag name
if children.tag == "size":
print "Sizable memory found",
child.findtext("size")

memory_banks.append(int(child.findtext("size")))

Ok so up to here I am ok. I find ( If you want the full xml let me
know) two blocks of system memory. It MUST be "System Memory" only.
Now how do I get a list of all of the children "nodes" of this. They
are named bank:N ( i.e bank:0, bank:1 etc [see below] ). For each one
of those there may ( or may not ) have some memory stuck in it. I can
tell if there is memory because a size is given. I want to a list of
all of the sizes. From there I can say you have sum(memory) in
len(memory) banks of total banks.
Click to expand...

once you've found a memory node, you should be able to simply loop
over all node children, optionally filter on the id attribute, and look for
size elements.

sizes = []

for elem in tree.findall(".//node"):
if elem.get("class") == "memory":
if elem.findtext("description") == "System Memory":
print "Found system memory bank"
# loop over subnodes
for node in elem:
size = node.findtext("size")
if size:
sizes.append(int(size))

print len(sizes), sum(sizes)

note that this assumes that the size is always in bytes. if not,
you have to check the units attribute; e.g.

size_elem = node.find("size")
if size_elem is not None:
unit = size_elem.get("units", "bytes")
size = int(size_elem.text)
...
