lxml

I've been trying to install lxml using pip install lxml and I get the error below. I've used apt-get install python-dev libxml2 libxml2-dev libxslt-dev before (suggested in other answers) but I still get the same error. I did not use control-c. pip install lxml Downloading/unpacking lxml Downloading lxml-3.2.4.tar.gz (3.3MB): 3.3MB downloaded Running setup.py egg_info for package lxml /usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'bugtrack_url' warnings.warn(msg) Building lxml version 3.2.4.

I've spent the last couple of days getting to grips with the basics of lxml; in particular using lxml.html to parse websites and create an ElementTree of the content. Ideally, I want to save the returned ElementTree so that I can load it up and experiment with it, without having to parse the website every time I modify my script. I assumed that pickling would be the way to go, however I'm now beginning to wonder.

I am using python 2,7.5 on mac 10.7.5, beautifulsoup 4.2.1. I am going to parse a xml page using the lxml library, as taught in the beautifulsoup tutorial. However, when I run my code, it shows bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml,xml. Do you need to install a parser library? I am sure that I already installed lxml by all methods: easy_install, pip, port, etc. I tried to add a line to my code to see if lxml is installed or not: import lxml Then python can just successfully go through this code and display the previous error message again,

Following on from Removing child elements in XML using python ... Thanks to @Tichodroma, I have this code: If you can use lxml , try this: import lxml.etree tree = lxml.etree.parse("leg.xml") for dog in tree.xpath("//Leg1:Dog", namespaces={"Leg1": "http://what.not"}): parent = dog.xpath("..")[0] parent.remove(dog) parent.text = None tree.write("leg.out.xml") Now leg.out.xml looks like this: <?xml version="1.0"?> <Leg1:MOR xmlns:Leg1="http://what.not" oCount="7"> <Leg1:Order> <Leg1:CTemp id="FO"> <Leg1:Group bNum="001" cCount="4"/> <Leg1:Group bNum="002" cCount="4"/> </Leg1:CTemp> <Leg1:CTemp
