Hi,

first of all: is there any reason you are not using the latest binary packages
of lxml 2.1?

Also: the mailing list of lxml is a better place to ask these questions than
the more general XML-SIG list.

You need to install libxml2 and libxslt and add the xslt-config script that
ships with libxslt to your program search path when building lxml.

It's generally recommended to build lxml statically against libxml2/libxslt on
Windows. There are some build instructions on the web page.

I'm new to Python too and ran into this problem also and couldn't find the
direct answer... 

Try this, it worked for me...

1. Visit:  http://sourceforge.net/project/showfiles.php?group_id=2435
http://sourceforge.net/project/showfiles.php?group_id=2435 

2. Download & Run: Automated MinGW Installer (make sure you check the base,
g++ and Make)

3. Update your PATH: Add the C:\mingw\bin directory to the system PATH

4. Create (or edit): C:\Python25\Lib\distutils\distutils.cfg and add the
following 2 lines:

[build]
compiler=mingw32

That should do it for you! It worked for me :)

I found this solution at:
http://livingpyxml.python-hosting.com/wiki/AmaraWindowsInstallTips

Message-ID: <20689034.post@talk.nabble.com>


Hello,

I am a xml parsing newbie and I am having a hard time because I am so new. 
I am trying to parse:

<?xml version="1.0" encoding="UTF-8"?>
<server>
	<config>
		<threads>100</threads>
		<runs>1</runs>
		<duration>200</duration>
		<process>400</process>
		<rampup>500</rampup>
	</config>
</server>

I want to grab the value of threads which is 100, runs which is 1, duration
which is 200, process which is 400, and rampup which is 500.

Here is my febal attempt at getting the values between the tags:

import xml.dom.minidom
import sys

class textHandler:      
    
    def parseFile(self):
      tags =
xml.dom.minidom.parse("/home/grinder/grinder-3.0.1/data/reportsInfo.txt")
      serverelements = tags.getElementsByTagName ( 'server' )
      for server in serverelements:
          print server.childNodes[0].data
          
x = textHandler()
x.parseFile()


Can anyone help?

Thanks,
Ron

Under the DOM model, the first child node in <server> is a text node 
containing the whitespace between <server> and <config>.  If you know there 
is only one threads element under each server you can use:

for server in serverelements:
    print server.getElementsByTagName('threads')[0].childNodes[0].data

But you will probably find ElementTree a much more useful xml library:

from xml.etree import ElementTree
tree = ElementTree.parse("/home/grinder/grinder-3.0.1/data/reportsInfo.txt")
print tree.find('config/threads').text

There's also lxml.objectify, which seems well adapted to your data.

    >>> from lxml import objectify
    >>> server = objectify.parse('thefile.xml').getroot()
    >>> server.config.threads
    100

Note how it shows 100, not '100'.

Subject: [XML-SIG] element-value in multiple namespace
Message-ID: <20081130202537.c56fec35.benkokakao@gmail.com>

Hello!

I'm currently struggling to extract some information from a gpx-file
(geodata in xml-format). You can see the xml-content here:
http://benko.login.cx/2008-11-21.xml

So far i've managed to get out most of the values with this function:

tree = etree.parse(gpxfile)
    gpx_namespace = "http://www.topografix.com/GPX/1/1"
    root = tree.getroot()
    trackSegments = root.getiterator("{%s}trkseg"%gpx_namespace)
    for trackSegment in trackSegments:
        for trackPoint in trackSegment:
            lat=trackPoint.attrib['lat']
            lon=trackPoint.attrib['lon']
            altitude=trackPoint.find('{%s}ele'% gpx_namespace).text
            time=trackPoint.find('{%s}time'% gpx_namespace).text


However, i have little idea what the syntax to pick out the
values of the Temperature- and Pressure-elements has to be, which have
an additional namespace, plus they
have a "gpxx:"-prefix. I've struggled yesterday night with
this but didn't succeed. Can someone give me a kick-off how this would
work?

Cheers
Christian

Then use that namespace to ask for them in exactly the same way as you did
above with the gpx_namespace.

Prefixes are not relevant. What counts is the namespace URI.

I'm afraid thats what i'm trying all the time. Using the script above
gives me a trackPoint-element - Running

>>> etree.tostring(trackPoint.find('{%s}extensions'% gpx_namespace))
'<extensions xmlns="http://www.topografix.com/GPX/1/1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
\n<gpxx:TrackPointExtension xmlns:gpxx="http://gps.wintec.tw/xsd/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://gps.wintec.tw/xsd
http://gps.wintec.tw/xsd/TMX_GpxExt.xsd">
\n<gpxx:Temperature>26</gpxx:Temperature>
\n<gpxx:Pressure>1020</gpxx:Pressure>\n</gpxx:TrackPointExtension>
\n</extensions>\n'

which is the subtree i'm looking for.

I'd assume i can
grab the contents of this with:

  ext_namespace = "http://gps.wintec.tw/xsd"
  trackPoint.find('{%s}extensions'% gpx_namespace)).find('{%s}
Temperature'% ext_namespace)

But this is not correct, the result is 'None'.
Imho this is exactly the same as further above where i extract
lon,lat,altitude,..., besides that i don't use gpx_namespace but
ext_namespace in the find().

Should the gpx_namespace be applied additionally to the ext_namespace in
the extensions-subelements as it is a subelement of the gpx_namespace?

Puzzled
